Cog Sci 1 Midterm 1 UC Berkeley exam | Questions and Correct Solutions | Latest Update 2024/2025 | Graded A+ oligodendrocyte - Answer -glial cell responsible for myelinating axons, thus insulating action potentials astrocyte - Answer -glial cell responsible for bringing in nutrients microglia - Answer -glial cell responsible for cleaning up dead cells neurotransmission - Answer -electrical signal through neuron translated chemically to next cell resting potential - Answer -a neuron at rest is charged at approximately -70mV stimulus (action potential) - Answer -something that causes the current neuron to depolarize toward the threshold potential depolarization - Answer -when all Na+ channels open if the threshold of excitation is reached repolarization - Answer -the peak action potential where K+ channels open and begin to leave the cell, causing the cell to be less positive. The action potential is polarization - Answer -the refractory period where an action potential cannot fire because K+ keeps leaving, making the action potential even more negative than normal Kandel's experiment - Answer -used 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 - Answer -neurons that fire together wire together (if two cells consistently fire at the same time, then the strength of the connection between them will grow str
