excitatory

Triggers neural firing

Excitatory describes something that stimulates or increases activity, particularly in biological systems.

An excitatory neurotransmitter makes a nerve cell more likely to fire.

An excitatory signal amplifies a response rather than dampening it.

The term contrasts with inhibitory, which suppresses activity.
