Autoregulation refers to mechanism by which an organ regulates blood flow to match the metabolic rate.

Autoshaping refer to responses that are learned in experimental situations even though they are not necessary to obtain reinforcement . Autoshaped behaviors, like pecking in pigeons usually appear to be part of the organism’s repertoire of “natural” behaviors. A type of sign tracking in which a pigeon comes to automatically peck at a response key because the key light has been associated with the response-independent delivery of food is an example of Autoshaping.

Autosome refers to a chromosome not involved in sex determination.

Autosomes refer to the the 22 pairs of human chromosomes that are identical in males and females (non-sex chromosome ). Humans generally have 22 pairs of Autosomes in each cell of the body.
