Various studies exist about these compartments – which controls the expression of the soul through the body, which is responsible for memory, intelligence, belief, hatred and love. The brain’s two hemispheres have different functions and specialize in different areas. For example, linguistic abilities and tongue functions are usually controlled by the left hemisphere, while musical abilities and the ability to comment and analyze complex images are controlled by the right hemisphere. However, it is not possible to state that the forebrain functions independently from the hemispheres of the brain. The Wernicke’s area, located on the upper tail of the temporal lobe, is responsible for language comprehension, and the Angular Gyrus that is a mediator between sound and vision, is responsible for linguistic and mathematical operations. For this reason, the Angular Gyrus is accepted to be related with superior consciousness and intelligence. Scientists have proven that intelligence and consciousness decrease more dramatically upon the destruction of these areas when compared to the destruction of the forebrain. Therefore, for the spiritual functions to be able to operate in the body, it’s essential that these areas of the brain function.

The more accepted view, at least today, is that spiritual characteristics and personality function independent of the brain. A convincing proof disregarding this view is that during many tumor surgeries, even though the body’s vital activities remain intact, after removing tissue from the brain, spiritual characteristics sometimes degrade. Another proof is the surgery performed to remove the forebrain of depressed patients (a prefrontal lobotomy). The patients vital activities were not disrupted upon surgery and their mood improved for a while. For a short amount of time, patients stopped suffering from serious neurological and psychiatric disturbances. However, when the patients were observed several years after the surgery, it was concluded that the patients lacked the functions of the forebrain and these surgeries were abandoned. The most prevalent side effects related to the removal of the forebrain were:

• Loss of the ability to solve complex social problems,
• Loss of the ability to take sequential steps in order to resolve a complex problem,
• Loss of the ability to multitask,
• Loss of determination, effort and desire to do activities,
• Loss of the ability for a community response when faced with a problem,
• Loss of ethical values and the feeling of shame,
• Loss of coherent thought even though the ability to speak and understand what is said is not lost,
• Instant emotional changes: from kindness to frustration, passion, violence and insanity,
• Inability to use artistic or naturally existing talents for the sake of a purpose.

These dysfunctions made it apparent that there was a correlation between the forebrain and spiritual characteristics.

Single neurons, not from the human brain, were inoculated in the lab and an experiment was carried out.. Studies showed that these neurons were not a means to highly intellectual capabilities, such as intelligence; whereas when neurons taken from the forebrain were inoculated and experimented on, it was found that they were a means to uniquely human capabilities like intelligence. Complex problem solving and the capacity to make discoveries were found to be correlated with the forebrain. It is not possible to explain such a fact without taking the soul into consideration. Spiritual characteristics such as sadness, happiness, joy, peace, patience, compassion, and love are all the results of complex interactions within the brain. However, it is not convincing to say that they are only results of electrical or chemical interactions within the brain.

The prefrontal area is where all thoughts coming from lower brain areas (such as sight, hearing, and feeling cortex areas, and the thalamus and hypothalamus) are gathered and processed to be enriched. Many information and memories gathered from different parts of the brain come together in the prefrontal area to be synthesized into deeper thoughts. Active memory is when different pieces of information are synthesized together and form a thought; and this thought is later acted upon. This allows to accurately surmise future events, and to plan for them.

It also allows for a rapid, appropriate response to the signals gathered by the five sensory channels. It allows for predicting the consequences of actions before performing them and for resolving problems of a complex medical, mathematical, ethical, moral, or philosophical basis. It can also postpone emotional responses for an appropriate time, measure the consequences of verbal and physical communications, use will power to measure the ethical and moral consequences of actions, and use information gathered from all channels to diagnose a problem. People who have damaged prefrontal cortexes, have serious difficulty synthesizing information and processing it to form coherent thoughts (active memory). This situation shows us that the prefrontal cortex enables consciousness and highly intellectual actions.

Another function of the prefrontal cortex is to enable focus about a specific topic. Taking this into consideration, the prefrontal cortex is semi related to attention. An existing proof for this is that people with damaged prefrontal cortexes are unable to concentrate and their focus is easily disturbed. Individuals whose prefrontal cortex has been removed or damaged can acquire a spiritual consciousness; however due to their handicap, they are unable to express their thoughts in a serial and sensible fashion for more than a minute. They can be easily distracted from the original subject. The prefrontal cortex allows an individual to accomplish a process of thought despite distractions, and allows for communication between the soul and the mind.

To sum it up, the prefrontal cortex is correlated with intellectual characteristics such as consciousness, intelligence, and self control, and also relates to how well we perform our moral values. For example, if the prefrontal cortex is unable to function, the individual does not feel shame anymore. This makes people believe shame is related only to the prefrontal cortex. However, the brain is merely a bridge between the body and the soul. Our brain is a bridge and curtain for our soul, which is the source of our spiritual characteristics. When we physically have a problem with our brain, the soul carries on its existence as before, however it is unable to express its consciousness, intellect, and will power in this material world.

Factors underlying variable DNA methylation in a human community cohort. L.L. Lam et al. PNAS October 16, 2012 vol. 109

The effect of environment on genes can be very profound. Our surroundings may not directly change our DNA sequence but it can surely dictate how our genes are transcribed. Epigenetics studies heritable changes in gene expression caused by non-genetic mechanisms, i.e. mechanisms other than the changes in the DNA sequence itself. DNA methylation is one of the major epigenetic modifications to regulate the gene expression. The addition of methyl groups on DNA sequence acts like a dimmer on a light bulb switch, which will turn certain genes on or off. A recent study showed that a person’s early life experiences shape their DNA methylation patterns. The research team discovered that childhood poverty (not socioeconomic status as an adult) is highly correlated to distinct methylation marks left on genes. Although children in rich and poor households have identical sets of genes, the degree of adversity or stress at home determines which combinations of those genes are activated or silenced through differential DNA methylation. One can imagine that such epigenetic changes might cause some alterations in the gene expression program of blind people to certain environmental signals or make them even more sensitive. Perhaps such changes could make some people more adaptive to harsher life conditions, hence enhance their survival. These findings suggest that environmental conditions early in life shape our epigenomes permanently thereby influence our life experiences, health and probably many other things that we are not yet aware of.

An alien planet next door

An Earth-mass planet orbiting α Centauri B. X.Dumusque et al. Published online 17 October 2012, Nature

Astronomers have just discovered an earth-size alien planet right next to our solar system. A new earthlike planet, named Alpha Centauri, is just 4.4 light-years away. That’s 40 trillion km away from earth! Although this rocky planet’s mass is similar to Earth’s, it orbits much closer (25 times closer than the Earth) to host star Alpha Centauri B. As a result, a year lasts 3236 days and the surface temperature of the planet reaches around to 1200 °C, which makes the planet incapable of supporting any life form we know. However, solar systems with a rocky world are usually predicted to have multiple planets. One possibility is that that Alpha Centauri A, the bigger sibling of Alpha Centauri B, might host some yet to be discovered unknown planets with more habitable zones. Although this recent discovery has sparked people’s dreams to travel to another star system outside of our planetary system, such an exploration mission unfortunately seems impractical in the near future. Even a cell phone-sized probe that is accelerated to 10% of the speed of light would need to travel non-stop for 40 years to reach the target. So, what is the next best thing to do? Will it be taking photos or dropping probes on the planet’s surface to study a potentially modified atmosphere? It seems like while astronomers work hard on the identification and characterization of this new star system, scientists should focus on developing super-fast propulsion systems, which will perhaps include new concepts like nuclear rockets and antimatter fusion drives.

Bad memories, substitute or suppress

Opposing Mechanisms Support the Voluntary Forgetting of Unwanted Memories
Benolt RG et al., Neuron, Volume 76, Issue 2, 450-460, 18 October 2012

For the nervous system, forgetting a memory is almost as complicated as creating one. A recent study probed the mechanism of how the brain allows us to voluntarily forget unwanted memories. Researchers utilized functional magnetic resonance imaging (fMRI) to examine the brain activity of participants who had learned associations between pairs of words and subsequently attempted to forget these memories by either blocking them out or recalling substitute memories. The fMRI results showed that two separate forgetting strategies looked equally effective yet they seemed to use different neuronal circuits in different parts of the brain. For memory suppression, dorsolateral prefrontal cortex inhibits neural activity in the hippocampus which is a critical region for recalling past memories. On the other hand, memory substitution specifically activates caudal prefrontal cortex and midventrolateral prefrontal cortex that are known to bring specific memories into awareness in the presence of distracting memories. These findings can help us to better understand the mechanisms of memory disorders such as posttraumatic stress disorder, and may ultimately help to develop effective treatments. At a more personal level, this study may direct us to explore how we deal with our unpleasant or unwanted memories. We might be surprised to realize that one approach might be working much better for us than another one. In other words, neuronal wiring in our brain might simply favor one approach over another.
