Eye position effects in oculomotor plasticity and visual localization.
For visual localization to remain accurate across changes of gaze, a signal representing the position of the eye in the orbita is needed to code spatial locations in a reference frame that is independent of retinal displacements. Here we report evidence that the localization of visual objects in space is coded in an extraretinal reference frame. In human subjects, we used outward saccadic adapt...
متن کاملEffects of visual deprivation on synaptic plasticity of visual cortex
TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...
متن کاملSpontaneous eye movements in goldfish: oculomotor integrator performance, plasticity, and dependence on visual feedback
To quantify performance of the goldfish oculomotor neural integrator and determine its dependence on visual feedback, we measured the relationship between eye drift-velocity and position during spontaneous gaze fixations in the light and in the dark. In the light, drift-velocities were typically less than 1 deg/s, similar to those observed in humans. During brief periods in darkness, drift-velo...
متن کاملEye proprioception used for visual localization only if in conflict with the oculomotor plan.
Both the corollary discharge of the oculomotor command and eye muscle proprioception provide eye position information to the brain. Two contradictory models have been suggested about how these two sources contribute to visual localization: (1) only the efference copy is used whereas proprioception is a slow recalibrator of the forward model, and (2) both signals are used together as a weighted ...
متن کاملBinocular oculomotor coordination and plasticity
Inchingolo in Trieste and Collewijn in Rotterdam) in their efforts to understand binocular oculomotor control, its adaptive properties and the relevance of the latter for pathologies that disrupt binocular coordination, e.g. strabismus. The conference was very fruitful in discussing the main results of this cooperation along with related findings by a number of other investigators working on si...
