Why
This research aims to understand how animals, including humans, make accurate sensory predictions and how the corollary discharge system adapts to timing changes in signals.
The Frontline Impact
How this affects you
Understanding the MCA's role in sensory prediction could lead to insights into human sensory processing disorders like schizophrenia by explaining the normal mechanism by which these predictions operate. This discovery highlights the value of studying animals with unique sensory abilities to answer general neuroscience questions.
