Document Summary

Biological psychology: the scientific study of links between biological and psychological processes. Understanding how we can use evolution to explain human: neuroscience, behavioural genetics behaviour, evolutionary psychology, behavioural microbiology. London taxi drivers: if we use our mind in specific ways we see physical changes, changes in the hippocampus, started with trainees. Neuron: have a cell body, communication to the remainder of the brain, collect information from other neurons and other cells, dendrites, axon, information itself is transmitted, on extra long axons to help the information move faster, myelin sheath. Action potential: collect information in the form of electricity, if enough of these + neurons the information will shoot on the axon to the other neuron. Synaptic transmission: electrical communication chemical communication. Deactivation: enzyme deactivation, binding to auto receptors, passively drift out of the synaptic gap, reuptake. Surgery is a better treatment than medicine as surgery implants medicine directly into the source rather than medicine trying to find it itself: schizophrenia.
