COMM 226 Study Guide - Neurotransmitter, Neuroglia, Reuptake
Document Summary
Neurons fired to visual cortex to perceive shapes to association cortex to figure out what shapes are. Neurons fired to amygdala feel fear. Neurons fired to hypothalamus autonomic ns response increased heart rate . Neurons fired in prefrontal cortex controlled thoughts: wait a second, it"s only an image, calm down . Amygdala (limbic system), parts of prefrontal cortex. When viewing image of romantic partner while in pain, activation of neural reward systems and. If we want to understand people, we have to understand their biology, too. Activation of the cell body must meet a threshold to fire. Once threshold is reached, fires down whole axon (all or none) List and describe key points about major neurotransmitters. List and describe the key functions of the major brain parts, including what would happen if they were damaged. Ap: electrical impulses that travles down the axons and allow neurons to communicates. Neurotransmitter: chemical messengers specialized for communication and released after synapse.
