Summary: A new study has provided the first complete, circuit-wide map of how the brain accurately predicts and cancels out self-generated sensory inputs.Every animal utilizes an internal motor command copy known as corollary discharge to differentiate its own actions from outside environmental signals. Every time a weakly electric fish generates an electrical pulse to navigate, its brain must instantly deploy a predictive cancellation signal to avoid blinding its own sensory organs.By capturing unprecedented intracellular recordings across every single step of this path within individual animals, the team discovered...
Traumatic events create lasting psychological effects that go beyond the moment, influencing thoughts, emotions, and how people manage everyday life. Whether caused by...
