Torpor
Definition:
(n.) Loss of motion, or of the motion; a state of inactivity with partial or total insensibility; numbness.
(n.) Dullness; sluggishness; inactivity; as, a torpor of the mental faculties.
Example Sentences:
(1) After arousal from torpor, within 2 h dendrites completely restored their structure.
(2) Bats have maximum life spans a minimum of 3 times those of nonflying eutherians--a trend resulting from neither low basal metabolic rate, the ability to enter torpor, nor large relative brain size.
