Why
Corollary discharge solves a universal problem: how animals distinguish sensory inputs coming from the outside world versus sensory inputs caused by their own actions.
The Frontline Impact
How this affects you
This discovery in weakly electric fish provides insights into a fundamental neurological process, corollary discharge, which is essential for sensory processing in many animals, including humans. Understanding this neural circuit could lead to better comprehension and treatment of human sensory processing disorders like schizophrenia.
