Brief Communications Microsaccadic Suppression of Visual Bursts in the Primate Superior Colliculus

Saccadic suppression, a behavioral phenomenon in which perceptual thresholds are elevated before, during, and after saccadic eye movements, is an important mechanism for maintaining perceptual stability. However, even during fixation, the eyes never remain still, but undergo movements including microsaccades, drift, and tremor. The neural mechanisms for mediating perceptual stability in the fac...

Microsaccadic response to visual events that are invisible to the superior colliculus.

Even when people think their eyes are still, tiny fixational eye movements, called microsaccades, occur at a rate of -1 Hz. Whenever a new (and potentially dangerous) event takes place in the visual field, the microsaccadic frequency is at first inhibited and then is followed by a rebound before the frequency returns to baseline. It has been suggested that this inhibition-rebound response is a ...

Neuro Forum Visual Suppression in the Superior Colliculus Around the Time of Microsaccades

Miniature eye movements jitter the retinal image unceasingly, raising the question of how perceptual continuity is achieved during visual fixation. Recent work discovered suppression of visual bursts in the superior colliculus around the time of microsaccades, tiny jerks of the eyes that support visual perception while gaze is fixed. This finding suggests that corollary discharge, supporting vi...
