Cog Sci 1 Midterm 1 UC Berkeley exam 2024 with 100% correct answers

oligodendrocyte correct answersglial cell responsible for myelinating axons, thus insulating action potentials astrocyte correct answersglial cell responsible for bringing in nutrients microglia correct answersglial cell responsible for cleaning up dead cells neurotransmission correct answerselectrical signal through neuron translated chemically to next cell resting potential correct answersa neuron at rest is charged at approximately -70mV stimulus (action potential) correct answerssomething that causes the current neuron to depolarize toward the threshold potential depolarization correct answerswhen all Na+ channels open if the threshold of excitation is reached repolarization correct answersthe peak action potential where K+ channels open and begin to leave the cell, causing the cell to be less positive. The action potential is sent. hyperpolarization correct answersthe refractory period where an action potential cannot fire because K+ keeps leaving, making the action potential even more negative than normal Kandel's experiment correct answersused sea slugs and classical conditioning to link the tail electrocution and touching of the gill, so if the tail was touched, the gill would retract (shows Hebbian learning) Hebbian learning correct answersneurons that fire together wire together (if two cells consistently fire at the same time, then the strength of the connection between them will grow stronger)
