PSYC 1F90 Study Guide - Quiz Guide: Axon Terminal, Action Potential, Voltage Spike
Document Summary
Describe the structure and functions of the glia cells and neurons. (pp. Describe what happens when a neuron is stimulated. Describe how sodium and potassium ions contribute to the neural impulse. (pp. Explain how neural impulses travel at the synapses. (pp. 89: synapse: the meeting points where neurons interconnect, a junction where info is transmitted from one neuron to another, describe a synaptic cleft. Explain the sense in which our activities are due to patterns of neural activity. (pp. 90-91: a neuron does a great deal more than just relaying messages it receives from thousands of other neurons, it must integrate them before it decides whether to fire a neural impulse. If enough excitatory psps occur in a neuron, the electrical currents can add up, causing the cell"s voltage to reach the threshold at which an action potential will be fired. Explain how they are related to behaviour. (pp.
