Document Summary
Psych: scientific studies of brain processes and behavior. Statistics - measures of central tendency what you"re going to look for is mean median and mode. Standard deviation measure of variability, how tightly or loosely bunched your data is. Correlation - explains the relationship between two variables. Positive correlation as one variable increases, the other increases. Cell body- branch things (dendrites), then axon, myelin sheath, axon ends with the terminal. The axon hillock is important because it is where the action potential starts. Action potential chemical event that spurs the communication between neurons. Sodium (positive ion) starts rushing into the neuron, which becomes depolarized and causes the action potential. It then depolarizes and refracts and goes back to resting state. Gabba the major inhibitory neurotransmitter in brain involved in movement. Dopamine involved in movement, and emotion and reward, schizophrenia hypothesis, too much dopamine in brain. Gludamate the major excitatory neurotransmitter in brain, involved in memory processes.
