The Brain: In this video Paul Andersen explains the structures and functions of seventeen major parts of the brain. He begins with a quick discussion of brain evolution and ends with a review of the major parts presented inside the brainstem, cerebellum, thalamus, and cerebrum.
Function: The brainstem controls several important functions of the body including: Alertness Arousal Breathing Blood Pressure Digestion Heart Rate Other Autonomic Functions Relays Information Between the Peripheral Nerves and Spinal Cord to the Upper Parts of the Brain Directionally, the brainstem is located at the juncture of the cerebrum and the spinal column. It is anterior to the cerebellum.
Lateral view of the cerebral cortex showing the principal gyri and sulci. Major structures include the central sulcus and the precentral (primary motor), premotor, and postcentral (primary somatosensory) gyri. Also note the gyri situated rostral to the premotor cortex, including the orbital gyri, which mediate higher order intellectual functions and contribute to the regulation of emotional behavior. Brocas motor speech area and Wernickes area (for reception of speech) are important areas…

The cerebrum, which is the largest part of the brain, is divided into four areas, or lobes, each of which houses different functions. The cerebrum is also divided into two hemispheres: the right, which helps you think creatively and the left, which helps you think logically. Hence, you have a right-sided frontal lobe and a leftt-sided frontal lobe....
“The two lobes of the cerebrum were called by the ancients Cain and Abel, and have much to do with the legend of the curse with Cain, which is literally the curse of unbalance. For the murder of the spirit of the equilibrium Cain is sent forth a wanderer of the earth.” ~ Manly P. Hall
BRAIN STEM -its function- and COMPRESSION -what it thus affects: Acting as a relay center, the brainstem connects the cerebrum and cerebellum to the spinal cord. The brainstem performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, and coughing. Ten of the 12 cranial nerves originate in the brainstem.
