“. . . 14-year-old Elliot got up from his bunk in his sleep, looked in the refrigerator, then, still asleep, walked out the back door. It would have been just another sleepwalking episode except that Elliot was in a camper-pick up truck traveling 50 miles an hour on the San Diego Freeway. Incidently; he escaped with cuts and bruises.”
—Coleman— It is one instance, in that; the major brain is asleep while the hind brain is functioning. Duality of consciousness is a natural phenomenon that occurs in spontaneity of reception and response. Cerebellum is the smaller of the two main divisions of the brain. The cerebellum is the chief organ for the control of coordination and posture. It receives fibers from the kinesthetic and vestibular pathways and has abundant interconnections with the cerebrum. The pons (Latin for “bridge”) lies above the medulla and is bridge between the two halves of the cerebellum, in that, fibers connecting the right and left hemispheres of that organ pass through the pons. The pons also has a number of nuclei or centers for the origin and termination of cranial nerves serving the head. The midbrain connects the pons and medulla to the brain proper and also contains reflex centers important in vision and hearing. Working up from the top of the spinal cord, we first come to the medulla which is essentially an enlargement of the upper cord where it connects with the brain. Running through the medulla on the way to and from the brain are the various spinal pathways. The medulla also contains a number of nuclei, or centers, that are important in the regulation of vital functions, such as, respiration and circulation. To the rear of the medulla lies the cerebellum, or “little brain.”
Cerebellum is the most important part of the nervous system for the coordination of movement and muscular contractions required to maintain posture.The cerebellum receives impulses from many sources, -principally the proprioceptive end-organs, the skin, the vestibular nuclei and the cerebral cortex. The pontine nuclei and the inferior olive relay fibers from the cerebral motor cortex and basal nuclei respectively to the cerebellar cortex of the opposite side. The cerebellar cortex integrates this information about body posture, limb position, and motor intention and sends efferent fibers via the cerebellar nuclei to the reticular formation, red nucleus and vestibular nucleus of the opposite side, whence fibers descend to influence motor cells in the anterior horns of the spinal cord; as these descending fibers cross again each cerebellar hemisphere controls the ipsilateral side of the body. Efferent fibers from the cerebellum also ascend to the contralateral thalamus through which the cerebral cortex is influenced. The cerebellum is therefore a great coordination center controlling the synergistic action of muscles during voluntary and automatic movements as well as adjusting posture.
In another instance of somnambulism, Bobby’s sleepwalking episodes were associated with nightmares, perspiring, and talking in his sleep .It does mean that fear, anxiety, or program incites for sleepwalking. Children may walk to another room of the house or even outside and may engage in rather complex activities.
As a matter of fact, it is the “hind brain” that gives rise to the duality of consciousness. In a normal person, its activities are manifested in the subconscious mind and, thus, it becomes difficult to detect the second consciousness. Hind brain is the division of the brain made up of the cerebellum, pons, and medulla. It is of things in pairs, front and back. Hind-sight, the perception of an event after its occurrence, takes into account the sensory-motor activities of major brain. In an intoxicated state of mind incoordination results and the activities of hind brain come into force.Mindfulness, meditation, or self-actualization is the outcome of hind brain while the major brain is in a tranquil state of mind. Besides, past remembering and future planning are influenced by hind brain. There are several pathological conditions that are accompanied with illusion, delusion, hallucination, and faulted thought processes. The unconscious activity for which the individual does not know the reason or motive for the act; psychic processes that cannot be brought to awareness by ordinary means; and the state of an individual who has suffered a loss of consciousness, such as, a person in faint or coma are the activities of hind brain. In a state of faint or coma the hind brain is active and if an individual is incited by voice in the ear there may be a response in one’s organism. These activities of hind brain are called involuntary or unconscious activities. In the field of involuntary or unconscious activities, further work or research is needed to substantiate, may be, the pathological conditions of psyche governed by autonomic motive states accompanied with subdued state of consciousness and central motive states.
