Electrical Activity of Neurons
This tutorial describes how neurons generate action potentials, and how scientists measure neuronal activity and record the firing of individual neurons.
Neurons encode information with electrical signals, such as action potentials. They transmit that information to other neurons through synapses. This Click & Learn describes these processes in more detail, shows how they can be measured using microelectrodes, and displays experimental results using graphs of neuron potential or voltage.
