Lesson #23
In Lesson #22, we examined the concepts of Intelligence and Wisdom as two connected yet different cognitive functions of the heart.
Insha-Allah, in this lesson, we will continue to examine the concepts of Intelligence, Wisdom, Nafs, Heart and Brain and their interconnectedness.
It is important that you follow these lessons in proper order to maintain continuity and progressive understanding of the topic.
Let us begin with the Brain.
As we have learned in the previous lessons, some important cognitive and emotive functions have been associated with the heart – قَلْب, according to the teachings of the holy Qur’an. This appears to be in contradiction with the common belief that holds the brain to be the locus of all cognitive and emotive functions. However, Neuroscientists, to this day, are unable to determine how (through what processes) and where exactly in the brain these higher cognitive functions occur.
The functions of the brain have been mapped and area commonly agreed upon. Let’s look at them.
Note for Inam: Insert the picture of the brain map attached to this file.
Here are some of the functions associated with the different parts of the Brain:
Frontal Lobe: Most anterior, right under the forehead. Has the following known functions.
– How we know what we are doing within our environment (Consciousness).
– How we initiate activity in response to our environment.
– Judgments we make about what occurs in our daily activities.
– Controls our emotional response.
– Controls our expressive language.
– Assigns meaning to the words we choose.
– Involves word associations.
– Memory for habits and motor activities.
Parietal Lobe: near the back and top of the head. The functions associated with it:
– Location for visual attention.
– Location for touch perception.
– Goal directed voluntary movements.
– Manipulation of objects.
– Integration of different senses that allows for understanding a single concept.
Occipital Lobes: Most posterior, at the back of the head. These are responsible for,
– Vision
Temporal Lobes: Side of head above ears. Functions:
– Hearing ability
– Memory aquisition
– Some visual perceptions
– Catagorization of objects.
Cerebellum: Located at the base of the skull. Functions:
– Coordination of voluntary movement
– Balance and equilibrium
– Some memory for reflex motor acts.
Brain Stem: Deep in Brain, leads to spinal cord. It is responsible for:
– Breathing
– Heart Rate
– Swallowing
– Reflexes to seeing and hearing (Startle Response).
– Controls sweating, blood pressure, digestion, temperature (Autonomic Nervous System).
– Affects level of alertness.
– Ability to sleep.
– Sense of balance (Vestibular Function).
Did you notice that none of the higher level cognitive functions are listed as functions of any part of the brain?
For example, which part of the brain is responsible for:
– Drawing conclusions from various pieces of the information stored in the brain.
– Making choices and decisions
– Weighing the risks and consequences of each option available.
– Beliefs, Values, Attitudes, Ethics and Morality.
– Making choices that are known to be destructive instead of the ones that are likely to be constructive.
– Arrogance, Vanity, Dishonesty, Jealousy.
– Love, Passion, Compassion, etc.
We know that during certain cognitive and emotive states, certain bio-chemical and electrical activity is going on in certain parts of the brain.
But, we don’t know if this activity is triggered from within the brain or from outside of it. What is triggering a certain thought process? Why does one person fall into pieces under certain pressures, and another doesn’t? What makes someone as strong and firm as a rock in face of hardships, and another a weak coward? What role does the brain play in all of these different reactions to our life events?
Neuroscientists to this day are struggling to understand the functions and limitations of the Brain.
In May 2004, a symposium was held at the Columbia University, New York on “Brain and Mind”. Leading neuroscientists gathered at this symposium. Participating scholars discussed current understandings and answers to key questions: How do the actions of individual neurons shape the function of neural populations? What is the underlying logic of signaling in complex neural circuits? How do dynamic mechanisms modify the processing of this information? And ultimately, how does the activity of neural ensembles generate cognitive and emotional behavior?
Perhaps they are looking at the wrong place for some of the answers.
It is true that the Brain plays a significant role in cognitive and emotive functions. However, from all the research so far, its known primary functions appear to be limited to:
1. Storage of information.
2. Governing the autonomous body functions, such as Breathing, Heart Rate, Swallowing, Reflexes to seeing and hearing, Sweating, Digestion, etc., as well as habitual behavior. (Even these functions may be altered by factors and events outside of the Brain.)
3. Identifying and categorizing sensory information from the sensory organs.
4. Maintaining awareness (consciousness), attention, appropriate body movements, balance and equilibrium, and reflexes.
In summary then, the Brain does play an important role in the cognitive, emotive and all the bodily functions, including human behavior. However, its role is mainly to store the information, to make it accessible, and to act upon the instructions, decisions and orders that come from somewhere else besides itself. Although a number of these functions are typically associated with the frontal lobe of the brain, but, as you read in one of the previous slides, one of the major quandaries of the neuroscientists is the question, “how does the activity of neural ensembles generate cognitive and emotional behavior?” Thus the Brain is a necessary organ, but its role is more of a general in the field who carries out the order of the commander-in-chief, the Heart.
Allah (swt) says in the holy Qur’an:
“لَهُمْ قُلُوبٌ لا يَفْقَهُونَ بِهَا وَلَهُمْ أَعْيُنٌ لا يُبْصِرُونَ بِهَا وَلَهُمْ آذَانٌ لا يَسْمَعُونَ بِهَا أُولَئِكَ كَالأنْعَامِ بَلْ هُمْ أَضَلُّ أُولَئِكَ هُمُ الْغَافِلُونَ – They have hearts wherewith they understand not, eyes wherewith they see not, and ears wherewith they hear not. They are like cattle,- nay even more misguided, for they are heedless (of the warnings).” (7:179)
Obviously, registering, categorizing, and storing the sensory information from the eyes and the ears are some of the known functions of the brain, but notice that this verse talks about not just these functions of the brain, but something beyond them; and that is the functions of reaching the correct conclusions from this information and to use it sensibly and prudently, which the brain is not capable of doing on its own.
Insha-Allah, in the next lesson, we will continue to explore the inter-relationship of these various concepts in our every day life.
