Document Summary
Chapter outline: how do scienists study the nervous system, how does the nervous system work, how do neurons work, how is the nervous system organized, structures of the brain, evoluionary psychology, brain side and brain size, neurological diseases. Tesing the behaviour of paients with brain damage. Electroencephalograms (eeg) recording brain acivity from the surface of the scalp. Neuroimaging techniques that show visual images in awake humans. Neurons (nerve cell) main building block of the brain. Interneuron carries informaion between neurons in the brain and the spinal cord. Astrocytes creates blood-brain barrier, inluences communicaion between neurons, and helps heal brain damage. One type of astrocytes is the stem cell, which creates new neurons. Oligodendroglia provides myelin to speed up transmission of neurons. Microglia cleans up dead cells and prevents infecion in the brain. Cell body contains nucleus, which provides energy for the neuron (c) Axon carries informaion away from the cell body (d).
