The Qur’an verses refer to prostration as a sign of being free of arrogance: “Only they (truly) believe in Our signs and Revelations who, when they are mentioned of them (by way of advice and instruction), fall down in prostration, and glorify their Lord with His praise, and they do not behave with haughtiness. (32:15).

Prostration (sajda) is the way to show respect to the Creator – not only for human beings, but also for angels and other creatures: “Before God prostrates itself whatever is in the heavens and whatever is on the earth of living creatures, and the angels (likewise, for) they are not arrogant.” (16:49).

Prostration has been practiced in Judaism and Christianity as well, sometimes with one’s knees and face on the ground, and sometimes as a full-body prostration: lying flat on the ground with the face down and the arms open. Even today in Eastern Orthodox, Roman Catholic, and Anglican churches, and amongst Ashkenazi Jews, these practices continue. This makes sense, for the Qur’an talks about a promise that God took from the Children of Israel to establish the prayer (2:83).

In summary, putting one’s face on the ground as a sign of respect or as a part of worship has been one of the central practices in all Abrahamic religions. The Almighty God wants His servants to make it a frequently observed practice that we bow down and put our foreheads on the ground in worship of Him. The spiritual and psychological impact of a prayer of this form can be immense, particularly in the long term, and should be discussed at length in another essay. Here we would like only to point out the neurological aspect of prostration and its connections.

Another The Fountain article discussed the function of the frontal brain lobe (“The Sinning Forelock,” Issue 51, 2005) and its importance in forming ethical and moral values:

“Frontal lobotomy is the term used for the surgical removal of the frontal lobe in patients with emotional disorders (1). It may be difficult today to imagine that an invasive procedure like destroying a large portion of the brain can be employed as a therapeutic approach. Yet, in 1949 the Nobel Prize in medicine was awarded to Dr. Egas Moniz for his development of the frontal lobotomy technique. (Strange enough, Moniz himself was shot in the spine and partially paralyzed by a lobotomized patient.) Tens of thousands of people were lobotomized following World War II . Although frontal lobotomy did not significantly alter the patient’s IQ or memory functions, some other profound side effects emerged.”

The negative impacts of this surgical procedure on the personality of these patients were so serious that frontal lobotomies had to be abandoned after some years. Instances of local injury to the frontal lobes have clearly demonstrated that after losing parts of the forebrain, a human loses much of their moral values, ethics, and many of the general traits that make them human.

We can see this by looking at the case of Phineas Gage (2). According his doctor, who followed Gage for 12 years after the accident (until his death), “He is fitful, irreverent, indulging at times in the grossest profanity (which was not previously his custom), manifesting but little deference for his fellows, impatient of restraint or advice when it conflicts with his desires, at times pertinaciously obstinate, yet capricious and vacillating … His mind was radically changed, so decidedly that his friends and acquaintances said he was no longer Gage” (2).

It is interesting to note here that it is the forehead (forelock) that is mentioned in the Qur’an as the sinning part of the head: “No indeed! If he does not desist, We will certainly seize and drag him by the forelock; a lying, sinful forelock!” (Alaq 96:15-16).

On a different note, the benefit of exercise and physical therapy has been well established in neural disorders. The main rehabilitative effect of physiotherapy in stroke patients and other neurological disorders is the elevation of neural activity in the spinal cord and the brain, which in turn encourages the neurons to rewire, i.e. form new connections and replace the networks that have been lost due to injury.

If we look at the Hebbian theory of learning, or neural plasticity (3) – which can be summarized as, “neurons that fire together wire together” – we can understand that when a subset of nerve cells in the central nervous system are somehow made to fire almost simultaneously, through exercise or other means, they begin to form connections. As a result, in injured patients, these new connections form a neural network that replaces or substitutes for the functions that are lost after injury.

Recent neuroscience research also shows that the rehabilitative effect is highly correlated with an increase in the blood flow to the brain area that is affected by the injury (4, 5). Contrarily, the blood circulation increases in an area of the brain within a few seconds as a response to increased neural activity because of a heightened demand for oxygen and glucose. Indeed, one of the most successful imaging techniques, the BOLD (Blood Oxygen Level Dependent) fMRI technique, completely depends on this phenomenon. These basic findings in neuroscience teach us that there is a close relationship between the local blood flow in the brain and the neural functioning, and this is a part of the process of eventually forming new networks.

Going back to the concept of prostration, lowering one’s head and putting the forehead on ground can elevate the blood flow to the frontal brain areas simply by the hydrostatic effect. We all know how blood rushes to the head when the legs are raised when lying down in the supine position. The neurological outcomes of hydrostatic blood pressures may not have been studied so far, as suggested by the lack of publications on this topic. However, in light of all the other evidence above, it would not be surprising to find out that the new neural networks form faster under higher blood flows and pressure to a local brain area.

Let us now recall the topics discussed above: prostration in Abrahamic religions, the role of the frontal lobe in forming ethical values, and the effect of blood circulation in forming new neural connections. All of this points us in one obvious direction. Prostration, or sajda, can increase the neural activity and promote new connections in the frontal lobe, a center that is instrumental in forming moral values. And this could be the neural basis of becoming more religious as one practices prostration as a part of his or her prayers. It also makes complete sense that The Creator asks His servants to worship Him with prostration that would make them better human beings, not only because of the spiritual experience, but also by endowing them with brain connections through prostration which will then function as receiving ears to future inspirations.

Despite advances in technology, computers still can’t come close to the power of the world’s most remarkable computer – the human brain.

Computing machines have seen three phases: the tabulating phase, the programmable phase, and now the new era of computing, the cognitive phase [1]. Tabulating machines performed a fixed task, whereas programmable machines could be reprogrammed to execute different tasks without any change in the hardware. Cognitive machines, however, promise learning and reasoning capabilities.

The possibility of such machines raises the question: is cognition the ultimate test for conscious existence? What do we know about cognition? How do we define intelligence? The questions go on and on. One thing, however, everyone seems to agree with is the fact that understanding the mechanism of human cognition is the key to developing advanced artificial intelligence, and cognitive machines.

Cognitive machines have the ability to learn, and they employ artificial intelligence to “reason.” Artificial intelligence is defined as, “The science of making machines do things that would require intelligence if done by men” [2]. The good news is that cognitive computing is no longer an esoteric pursuit of some futurists. It is, and has been, essential for the operation of many big-data driven processes. The 21st century has been flooded with data coming from almost every aspect of our lives. Technology has made it possible to generate data at an exponential rate. Temperature distribution throughout our buildings, the number of people diagnosed with cancer in the last six months, real-time changes in customer preferences, ethnic profiles of college applicants, and the top three words trending in online conversations at this very moment, are some examples of the kind of data available today.

As the amount of data generated increases, it also becomes harder and harder to process and make sense of the data collected. Our “greedy and ambitious” human nature does not want to waste, and it wants to use every bit of available data. This is where it becomes imperative to have a computing machine that goes beyond performing pre-programmed tasks and learns as it goes, without human interference. For this kind of computing, we need cognition.

The biggest challenge in imitating human cognition is to understand how cognition happens in the brain. It is obviously beyond our ability to monitor such activity that is constantly taking place in our brains, let alone recreating such marvels in the first place. Nevertheless, it will be a great achievement if we can manage to somewhat imitate human cognition, even partially. It would open a whole new era in terms of what can be achieved from a computing standpoint. For instance, the entire curriculum of a college degree can be processed by a cognitive machine in a fraction of a second; such machine can digest the whole of medical literature in a short period of time, provide human doctors with second opinions on their diagnoses [3].

Despite the fact that there have been substantial improvements in designing “intelligent” computing machines, mimicking the hardware of the human brain and simulating its decision-making processes, have posed three fundamental challenges: a hardware with comparable processing power and memory, a software algorithm to implement intelligent behavior, and the necessity of both being self-adapting and self-improving.

First of all, human intelligence has not been fully characterized – its capabilities and limitations are still unknown. This lack of knowledge makes it difficult, and perhaps even impossible, to reduce such intelligence to smaller, or simpler, modules. Therefore, we don’t have a good handle on how to mimic the human brain in a behavioral sense.

The second major problem is that we are still far away from having the hardware on which our “intelligence” software could run. Implementing intelligence in conventional computing machines, evidently, seems to be a futile undertaking. Programmable machines are no match for human brains; even the fastest supercomputers, taking advantage of thousands of processors, is able to mimic just one percent of one second worth of human brain activity-and even that takes 40 minutes [4]. Therefore, cognitive computing machines must incorporate different hardware architecture from conventional computers to achieve cognition comparable to humans. IBM’s SyNAPSE chip is one example of hardware inspired by the brain, and it has the potential to carry out the required, intense computations.

Lastly, the human brain and its cognitive power are constantly changing. Depending on various factors and experiences, our brains can improve or deteriorate; this is also true of our cognitive power. However, such improvement or deterioration could be in the form of a change in the physical structure or the amount of capacity utilized [5]. Such dynamic flexibility, also called Brain Plasticity [6], is essential to our intelligence. At this time, no self-evolving computing hardware has been worked out. However, promising developments have been reported with respect to cognitive computing machines that can learn – that is, they can make deductions and reach conclusions that are not preprogrammed.

Along the way, human supervision will be the ultimate guide in perfecting such imitation. Therefore, human cognition, taken for granted in our daily lives, remains to be the final frontier for our thousands-years long technological journey. Once again, the creation set the boundaries for human development.

These special functions are responsible for analyzing sensory data, performing memory functions, learning new information, forming thoughts, and making decisions. Given this, cognitive science deals primarily with the functioning of the brains frontal lobe, which is responsible for cognition (the act or process of knowing, including both awareness and judgment) and memory. The brains prefrontal area enables concentration, attention, and the elaboration of thought. As the brains gatekeeper (judgment and inhibition), it also is responsible for personality and emotional traits. One of the frontal lobes main functions is memory, a very important topic in cognitive science.

Memory

Memory is defined as the power or process of reproducing or recalling what has been learned and retained, especially through associative mechanisms. It is also the store of things learned and retained from an organisms activity or experience, as evidenced by structure or behavior modification as well as recall and recognition.

Just like any other human trait, memory can be empowered and improved. How this is accomplished usually depends upon the individual. Many such techniques and tricks are advertised and marketed in daily life. While some actually work, most are like overloading our already full memory files. Eventually, it comes down to tricks vs. power, just like in sports. Consider the following analogy: If an Olympic boxer wants to improve his skills, should he watch pro-boxing matches on TV or punch a vinyl speed bag to train the muscles he needs to overpower his opponent?

This example might seem a little strange, for it depends heavily upon muscles. But, surprisingly, it really is relevant to the brains memory center, for recent developments in cognitive science show that a specific area behind the forehead (in the pre-frontal cortex) houses the brains memory muscle (1) ”the working memory. The discovery was made possible by advances in such brain-imaging technologies as PET and MRI scans.(2) Suppose you are studying for an exam and have to wade through a mound of reading material, or have to make a 10-digit phone call without the aid of a phone book, or are under a lot of pressure to answer questions rapidly or to make a snap decision. It is your working memory that decides what is relevant and where to best store such data for quick retrieval upon demand.

Developing our memory muscle

Pharmaceuticals, memory books, mnemonic tricks, seminars, and mental chronometrics (3) say that we develop our memory muscle and thereby improve our memory power. In reality, our memory muscle is our heads chief executive, for it is in charge of receiving, organizing, encoding, filing, and retrieving just about anything we learn, as well as for all planning and decision-making activity.

This activity is also known as psycho-interactive intelligence, for such tasks challenge all of the powers of working memory, including short-term memory, concentration, and mental speed. Computer-based exercises (CBEs) function in the same way. And, since they are psycho-interactive, they customize new challenges via simultaneous analysis and measurement. In addition, they usually are far more entertaining.

In fact, our memory muscle actually determines how quick, sharp, and focused our thinking is. According to Life magazine (July 1994): Evidence is accumulating that the brain works a lot like a muscle”the more you use it the more it grows. Although scientists had long ascertained that the brains chemistry was hard-wired by adolescence and inflexible in adulthood, its newly discovered ability to change, grow, and adapt is apparently with us well into old age.

NASA continues to make extensive use of training exercises to improve the brainpower of astronauts and pilots. Computer models of the brains functioning also are used in determining how to improve brainpower. Due to such research, they have been able to tap and train the brains memory muscle.

Mind Machines and Pharmatronics

The term mind machines refers to a large variety of technologies that affect ones brain: HemiSynch tapes, light and sound machines, cranial electrical simulation (CES) devices, biofeedback, biocircuits, lucid dreaming tapes and machines, consciousness alteration software, and sensory deprivation tanks. They are designed to transform the users brain waves into a wide variety of new patterns: from focused and alert to creative and ultra-relaxed, meditative to twilight receptive/learning state, or to different states of sleep. It is like instant brainwaves–ready in seconds on demand.

Bio-entrainment is the process of causing neurons to function in a desired manner. For example, a person with attention deficit disorder (ADD) cannot focus due to slow theta rhythms and desynchronous beta waves. Mind machines, especially light/sound and biofeedback, can help break these brain waves out of their scattered gridlock and drive them into open focus (theta) or closed focus (beta) patterns. Bio-entrainment also can enable people to focus better, relax or dive into deep meditation, induce creative or intuitive states, or to enter a deep sleep state quickly.

Encouraged by mind machines, pharmatronics (neuroscience) has induced researchers to postulate the psycho-physiological principle: Every psychological state has a corresponding measurable physiological (i.e., physical, electrical, and biochemical) state, and vice versa. For instance, using biofeedback to reach a state of deep relaxation and serenity (i.e., meditation) may cause the pituitary gland to produce endorphins that make you feel real good. This electronic-to-pharmacological effect, known as pharmatronics, is like an electronic drug or a device (e.g., a computer, game player, biofeedback device, or even software), for it alters the brains electrical (brain wave) pattern and, hence, its biochemical (pharmacological) profile.

One of the first notable pharmatronic agents was Tetris, a computerized puzzle game. Using PET scans, Dr. R. Haier discovered that first-time Tetris players experienced a significant increase in their cerebral glucose metabolic rate (GMR), indicating that their basic brain energy consumption was soaring.(4)

Computer-based exercises (CBEs)

Psycho-interactivity is not the same as interactivity. Clicking on a hyperlinked button to go to another page is interactive, whereas a psycho-interactive activity involves a computer taking the user through a series of mental challenges. But it does not stop there, for it also analyses the individuals reactions and then adjusts the level of complexity in subsequent challenges to ascertain the full potential of the players memory recall, thinking, and decision-making speed. Thus it renders a dynamic brainpower analysis, whereas most mental ability tests are static.

Since the brain is like a muscle, it must be challenged with the appropriate kind of resistance if it is to develop and grow. To develop any muscle, one has to engage in anaerobic exercises that feature a resistance or load that is very difficult to lift more than 10 to15 times (reps). Aerobic exercises (e.g., using a weight that you can lift 100 times), will not develop the muscles power. This is also true with the brain, for it will not develop only by thinking harder (an aerobic activity). What it requires is an anaerobic-like challenge, such as learning a new skill. Playing chess or mastering a new judo move can stimulate the brains neural dendrites to grow. However, the best anaerobic exercise is one that challenges the person to exert maximum mental energy, like running the 100-meter dash instead of a mile. This is what CBEs do.

CBEs also lower the noise in the brain, which leads to a more accurate reading and processing of information. The brains learning and testing is much like computers”its power is indicated by its speed, efficiency, and capacity for reading, filing, and recalling information.

CBEs are a synthesis of cognitive science, educational psychology, computer science, biofeedback, and psychophysiology. In addition to psycho-interactivity, add the law of psycho-physiology: If you can receive immediate on-line measurement of anything, whether it is your heart rate or brain waves, you can control it.(5)

In one experiment, astronauts used cognitive challenges every day and reported back to Houston so that their brains functioning could be recorded for that day. Subtle changes in cabin CO2, CO, ionization, and so on were found to have measurable effects on their brainpower and performance. CBEs do something like this, but their interactivity makes them more challenging and allows researchers to determine good or bad days in terms of brainpower.

Physical, perceptual, and cognitive reflexes are important in athletics. Contrary to common belief, reflexes can be trained and improved. There is plenty of research on how diet and nutritional supplements effects mental and physical performance. But training can sharpen and hone all of three reflexes. Psychology and physiology books say there is a limit to how fast one reacts to a simple stimulus, such as a car suddenly stopping in front of you on the freeway. The limit is assumed to be 150 milliseconds. But CBEs have reduced this to 100 milliseconds.

CBEs can improve perceptual reflexes (seeing speed). Moreover, some cognitive reflexes, strangely enough, are not highly correlated with physical reflexes. Just because an athlete has good hand-eye coordination and reflexes does not guarantee athletic success when the reaction is based on making a split-second cognitive choice or decision. Cognitive reflexes also can be improved.

Brain software in clinical studies

CBEs that analyze the brain and compute the users IQ may have an important role in studying and detecting Alzheimers, a progressive brain disorder. Josh Reynolds points out that while Alzheimers only affects 4 to 5 million people in the US, PMI (Premature Mental Impairment) is estimated to afflict over 50 million Americans. PMI typically manifests itself as loss of sustained concentration, memory, and mental quickness. It has many causes, such as undetected strokes, poor nutrition, head injury, alcohol and tobacco abuse, and depression.

However, the most prevalent cause of potentially serious brain deterioration may be cortisol, an adrenal hormone produced as a byproduct of stress. Recent research suggests that cortisol may actually kill brain cells and even lead to Alzheimers if the stress is not detected and treated. Ironically, the very medications used to treat stress (e.g., Valium) temporarily impair physical and cognitive reflexes, especially when dosages are too high or mixed with other drugs or alcohol.

CBEs can show the subtle early stages of stress-related memory loss, and can be used to titrate the dosage levels of anti-anxiety and anti-depressant drugs. Thus, they can minimize the temporary impairment mentioned above while maintaining the medications therapeutic efficacy. CBEs are developed on a computer science platform and thorough research into cognitive chronometrics, defined as the direct active computer-assisted measurement of the brains function. CBEs also can diagnose the early stages of a brain disorder before the onset of clinical symptoms. In addition to Alzheimers, CBEs are used to study and detect ADD and head trauma recovery.

The early stages of dementia, especially Alzheimers, are typically characterized by a breakdown in short-term memory. The primary breakdown is believed not to be in memory retrieval, but in the memory consolidation and storage phase, which are believed to be delegated to the hippocampus. According to CDI president Josh Reynolds, one of the earliest markers of Alzheimers is in the cholnergic system in the hippocampus.

PMI is characterized by a loss of sustained concentration, memory, and mental quickness. CBEs assess six areas of neuro-cognitive functions: physical reflexes, perceptual reflexes and thresholds, cognitive reflexes, working memory capacity (short-term memory), neuro-cognitive processing efficiency (concentration/attention), and neuro-cognitive processing speed (mental quickness). This is accomplished by measuring cognitive states (or status) and subtle changes in cognitive states.

CBEs also provide a reflective measure of neural noise, which is measured by analyzing, among other proprietary variables, the standard deviation (consistency) of the subjects intra-trial reaction times.

Conclusion

As in any field of science and life, computers are becoming a ubiquitous element in cognitive science. With its potential prospects and uses, the computer continues to offer many opportunities to improve our life. This article focused on some of the ways in which a computer can be used to aid the brains memory function. However this is just a crawling stage, and the field essentially remains wide open for researchers.
