Document Summary

Psychologists working from a biological perspective study the links between biology and behaviour. Humans are biopsychosocial systems in which biological, psychological, and sociocultural factors interact to influence behaviour. Understanding of the relationship between the brain and mind has evolved over time. Gall: bumps in head and stuff something like that, phrenology. Nerve cells conduct electricity and communicate through chemical messages across tiny separating gaps. Specific brain systems serve specific functions and information is integrated to construct a wide range of experiences. The adaptive brain is wired by experience. Receive signals through the dendrites and send signals through axons. In ms, the myelin sheaths often breaks down. Glial cells provide the myelin sheaths and support, nourish, and protect neurons, also help with thinking and learning. Can exceed a threshold and the neuron can fires, which transmits an electrical impulse. Communicates with other neurons and processes information between the sensory input and motor output.
