The effect of saccade metrics on the corollary discharge contribution to perceived eye location.
Corollary discharge (CD) is hypothesized to provide the movement information (direction and amplitude) required to compensate for the saccade-induced disruptions to visual input. Here, we investigated to what extent these conveyed metrics influence perceptual stability in human subjects with a target-displacement detection task. Subjects made saccades to targets located at different amplitudes ...
متن کاملSaccadic Corollary Discharge Underlies Stable Visual Perception.
UNLABELLED Saccadic eye movements direct the high-resolution foveae of our retinas toward objects of interest. With each saccade, the image jumps on the retina, causing a discontinuity in visual input. Our visual perception, however, remains stable. Philosophers and scientists over centuries have proposed that visual stability depends upon an internal neuronal signal that is a copy of the neuro...
متن کاملQuantifying the spatial extent of the corollary discharge benefit to transsaccadic visual perception.
Extraretinal information, such as corollary discharge (CD), is hypothesized to help compensate for saccade-induced visual input disruptions. However, support for this hypothesis is largely for one-dimensional transsaccadic visual changes, with little comprehensive information on the spatial characteristics. Here we systematically mapped the two-dimensional extent of this compensation by quantif...

The main purpose of this study was to determine the effects of word length and font type of eye movement (fixation, saccade, regression) during reading Persian familiar and unfamiliar passages. 29 female students of Shahid Beheshti University Education & Psychology Faculty participated in this study. Stimuli consisted of four different texts consisting of familiar text-lotus font, familiar-pen ...
متن کاملAltered processing of corollary discharge in thalamic lesion patients.
Accumulating evidence suggests that thalamic nuclei relay corollary discharge information of saccadic eye movements, enabling the visual system to update the representation of visual space. The present study aimed to explore the effect of thalamic lesions in humans on updating-related cortical processing. Event-related potentials were recorded while four patients with impairments in using corol...
