Document Summary

Psyc 200 chapter 4 & 5 notes. Testing the behaviour of patients with brain damage. Electroencephalograms (eeg) recording brain activity from the surface of the scalp. Neuroimaging techniques that show visual images in awake humans. Receives signals from neurons or sense organs. Sends signals to other neurons, muscles or organs. The human nervous system is comprised of two kinds of cells: neurons have the basic features in common with other cells of the body, but have a very distinct shape. Every neuron receives input from many other neurons: able to communicate with each other via, electrical signals (within the neuron, chemical signals (between neurons, they have an: i. ii. Inter-neurons receive input from and send output to other neurons ii: motor neurons have their cell body in the spinal cord. Average of 10,000 connections (synapses) for each neuron. There are 100,000,000,000,000,000 neural connections in the brain. *afferent axon brings information into a structure (sensory neurons)
