Physiology of the Brain: Functions
People often take their brain function for granted. Although thinking and willfully performing most actions are obviously carried out through conscious thought processes, many of our bodily functions such as regular breathing, blinking and yawning are under the control of the brain.
Specialized functions of the brain are under the influence of the different brain centers which act in a coordinated manner. Networks of billions of cells work like parallel processing units upon which artificial intelligence machines or computers are being modeled. Of course, the brain, in coordination with the rest of the nervous system is much more superior to any computer, machine or robot.
The electrochemical processes that take place in every brain function involve the release, binding and reabsorption of chemicals known as neurotransmitters within the synapses or junctions between cells. Balance among the different types of neurotransmitters like acetylcholine, dopamine and serotonin is important to maintain homeostasis. Many brain disorders or neurologic conditions are thought to be brought about by certain imbalances in the production, release or reabsorption of these neuro-chemicals.
