What is boredom in biological sense

Answer 1

Boredom  is marked by an empty feeling, as well as a sense of frustration with that emptiness. When you're bored you may have a limited attention span and lack of interest in what's happening around you. You may feel apathetic, fatigued, nervous, or jittery.

boredom is some combination of an objective lack of neurological excitement and a subjective psychological state of dissatisfaction, frustration or disinterest, all of which result from a lack of stimulation.
