Document Summary

Any activity in the world is associated with electrochemical events in the brain that allow us to sense the. Page | 1 activity (cid:8211) not the activity itself. Researchers have been continuously trying to determine the structure and functions of the structures. In this case both the functional and structural information is vital for comprehension. The cns consists of the brain and spinal cord while the pns consists of all nerves that innervate in and out of the cns. The brain is ~3. 0-3. 5 lbs and consumes 20% of our body(cid:8217)s oxygen. Glial cells are responsible for housekeeping functions while neurons are the cells that perform the interesting functions. Glial cells outnumber neurons by a large margin. Reductionism can occur with this because it is difficult to elaborate complex behaviours (i. e. altruism, selfishness, etc. ) with the activity and connections of 100 billion neurons. The explanations of neurons become so accurate that they become futile.
