A saccade is a rapid, conjugate, eye movement that shifts the center of gaze from one part of the visual field to another. Saccades are mainly used for orienting gaze towards an object of interest. Saccades … See more There are several terms used to characterize saccades: 1. Amplitude:The size of the saccade, usually measured in degrees or minutes of arc. A higher amplitude means the … See more Saccades are largely initiated by one of two brain regions: the frontal eye fields, a region of the frontal lobe just rostral to the premotor cortex, and the superior colliculus of the midbrain. The majority of voluntary saccades … See more Voluntary, endogenous saccades are self-directed eye movements that can be generated in response to command; they may require a complex volitional process with intricate cortical … See more bittitan teams meetingsWebDuring rapid eye movements, motion of the stationary world is generally not perceived despite displacement of the whole image on the retina.
