excitability
Tendency toward arousal
Excitability is the tendency to become easily excited or agitated.
In everyday use, it suggests someone who reacts strongly to stimuli—prone to enthusiasm, nervousness, or emotional volatility: The puppy's excitability made training difficult.
In physiology, excitability refers to a cell's capacity to respond to stimulation, particularly nerve and muscle tissue generating electrical impulses.
