excitation
State of activation
Excitation is the act of exciting or the state of being excited—typically in technical contexts.
In physics, excitation is the addition of energy to a system, raising electrons or atoms to higher energy states: The laser works by excitation of electrons.
In biology, excitation refers to stimulating a nerve, muscle, or organ into activity.
The word overlaps with excitement but tends toward scientific rather than emotional contexts.
