Inhibitory Signals

Definition

These are signals in the nervous system that decrease the likelihood of a neuron firing an action potential, or "message."

Related terms

Hyperpolarization: This is an increase in a cell's membrane potential, making it more negative and less likely to fire an action potential.

GABA (Gamma-Aminobutyric Acid):

This is a major inhibitory neurotransmitter in the brain that helps to slow down neuron activity.

Synaptic Transmission:

This is the process by which one neuron communicates with another by releasing neurotransmitters at a synapse.
