In larval zebrafish, saccadic suppression in the optic tectum lasts over 3,000 ms and selectively boosts the salience of ecologically relevant stimuli.
- Why it matters: The neural origin and functional role of saccadic suppression are debated, beyond compensating for image shifts during rapid eye movements.
- What they did: The study linked saccadic suppression to larval escape behavior, then used electrophysiology to show retinal ganglion cells initiate it in a spatial frequency-dependent way. Calcium imaging with 360° visual stimulation and behavioral tracking showed motor signals strengthen peri-saccadic suppression in the optic tectum.
- The result: Suppression is much weaker and more short-lived for hunting or escape-related stimuli than for global flashes, increasing tectal salience for ecologically relevant inputs after saccades.
