What is the True Origin of Consciousness? - William Juckett

| No Comments

Where does consciousness reside? The question of interest here is what part of the brain is responsible for self-awareness? humans highly developed cortex is the part of the brain responsible for human's self-awareness.
Consciousness appears to be all about the constant activation of the cortex. This activation of the cortex that keeps us self-aware and conscious begins in the Reticular Activating System, which is a group of nerve cells in the brain stem. These nerve cells then project up to what is essentially a relay station called the thalamus. The thalamus then sends projections out to all the areas of the cortex; it is this system that appears to keep our cortex activated. This is how doctors and researchers anatomically explain consciousness and self-awareness. Is it as simple as nerve impulses activating our cortex that creates the unique self-awareness, this knowledge that we are different from others and that we are in control of ourselves?
Based off this explanation, does this system slow down or shut off when we are unconscious? When a person, due to injury, is put into a coma is it due to damage that was caused to this system? Is a coma due to the brains inability to continually activate the cortex, and is the recovery time for a person in a coma related to their brains ability to "fix" or heal the damaged that was caused?
Unconsciousness like sleep. following the anatomical explanation, must be due to the system being slowed down or shut down. Forced unconsciousness must be due to damage to this system. The extent of this damage is what determines if there is a chance of recovery, and if there is, how long the recovery will take before a person regains consciousness.
