Document Summary

Psychology 100 lecture 3 neuroscience & behavior. What is it: you manipulate some event or variable so that people experience it one way or another way and look to see if differences in behavior occur. Gain control over the situation: weaknesses: lack external validity. Central tendency measures: mode most often reported score, mean average score, median middle score. Neuroscience & behavior: neurons and neural communication, neurons/neural impulses, neural communication, neurotransmitters, nervous system, structure and function, reflexes vs. neural networks, the brain, studying the brain, brain regions/function, hemispheric differences, gazzaniga article/video. Dendrite the in-box it receives signals from: sensory structures (like taste buds, other neurons. Axon the out-box (axon-away), it sends signals to: other neurons, effector cells (muscles) Myelin sheath a fatty substance that encases the axons of some cells: increases the speed of transmission. Axon terminals (book calls buttons - axon terminals : stores and eventually releases enzymes called neurotransmitters" (nt).
