A hypothetical mechanism or location in the brain that regulates appetite and controls hunger signals.
Coined from 'appetite' (from Latin 'appetitus') plus the suffix '-stat' (from Greek 'statos' meaning 'standing still' or 'causing to stand'). Created in the mid-20th century for scientific terminology.
Scientists once believed there was an 'appestat' that perfectly regulated hunger like a thermostat regulates temperature—but the brain's hunger control is much messier and involves multiple systems, so while the word stuck in some research, the concept was oversimplified.
