Document Summary

Biological psychology - the scienti c study of links between biological and psychological processes. There are many times of biological psychologists: behavioural neuroscientists, neuropsychologists, behaviour geneticists, physiological psychologists, biopsychologists. Everything psychological - ideas, moods, urges - is simultaneously biological. The computer is a good analogy to the mind and the nervous system. Basic unit of the nervous system: the neuron. Neurons, unlike other cells, talk to other neutrons in a fairly direct way. Cell body (soma) - cell nucleus with chromosomes: like any other body cell, fed by oxygen/sugars carried by blood. Axon - transmits information / signals to other neurons, to muscles, and to glands. Dendrites - receive information from other neurons. Every neuron has both axons and dendrites, often hundreds or thousands of each, each one communicating with hundreds or thousands of others - and they can also communicate with the muscles and the glandular system.
