Electrical Activity of Neurons

Summary

Measuring neuronal activity, generating action potentials, and recording the firing of individual neurons.

Neurons encode information with electrical signals and transmit that information to other neurons by synapses. The action potential is a very important electrical signal, often called a spike because it typically occurs in less than a second and involves a big voltage change, for a cell, of many tens of millivolts.
