TLDR
Parietal cortex both anticipates theretinal consequences of eye movements and updates the retinal coordinates of remembered stimuli to generate a continuously accurate representation of visual space.Abstract:
Every eye movement produces a shift in the visual image on the retina. The receptive field, or retinal response area, of an individual visual neuron moves with the eyes so that after an eye movement it covers a new portion of visual space. For some parietal neurons, the location of the receptive field is shown to shift transiently before an eye movement. In addition, nearly all parietal neurons respond when an eye movement brings the site of a previously flashed stimulus into the receptive field. Parietal cortex both anticipates the retinal consequences of eye movements and updates the retinal coordinates of remembered stimuli to generate a continuously accurate representation of visual space.read more

Active Vision in Parietal and Extrastriate Cortex
Elisha P. Merriam,Carol L. Colby +1 more
TL;DR: The central hypothesis is that a corollary discharge of the eye movement command updates, or remaps, an internal representation when the eyes move, and shed new light on the neural circuitry involved in producing a stable and coherent perception of visual space.

Movement prediction and movement production
Mark Wexler,François Klam +1 more
TL;DR: The authors studied the difference between active and passive movement prediction by asking observers to estimate displacements of an occluded moving target, where the movement was driven by the observer's manual action or was passively observed.

TL;DR: The results indicate that fields in the pre-supplementary motor area, the intraparietal cortex, and the prefrontal cortex function as a part of the neural network involved in the learning of sequential saccadic eye movements.

The phase of ongoing EEG oscillations predicts the amplitude of peri-saccadic mislocalization
Douglas McLelland,Douglas McLelland,Louisa Lavergne,Louisa Lavergne,Rufin VanRullen,Rufin VanRullen +5 more
TL;DR: The degree of perceived mislocalization is correlated with the phase of a theta-frequency oscillation prior to saccade onset, and this concludes that spatial updating processes are indeed linked to rhythmic processes in the brain.

TL;DR: A composite thin film resistor is disclosed, including an electrically inert substrate upon which is deposited a nickel-chromium alloy thin film, and an overlying second thin film - which is initially deposited as metallic tantalum - which provides a very high degree of environmental protection with respect to the Ni-Cr film.

Memory related motor planning activity in posterior parietal cortex of macaque.
J. W. Gnadt,Richard A. Andersen +1 more
TL;DR: Unit recording studies in the lateral bank of the intraparietal cortex (area LIP) have demonstrated a response property not previously reported in posterior cortex, which appears to represent a memory-related motor-planning signal encoding motor error in the Rhesus monkey.

Behavioral enhancement of visual responses in monkey cerebral cortex. I. Modulation in posterior parietal cortex related to selective visual attention
TL;DR: It is suggested that the role of area 7 in visual attention may be mediated by the enhancement of visual responses to selected stimuli, which resembles the psychological phenomenon of selective spatial attention.

Eye position effects on visual, memory, and saccade-related activity in areas LIP and 7a of macaque
TL;DR: The present results indicate that this modulating effect of eye position may be a general one, as it is found in 3 types of responses in 2 cortical areas, and it is proposed that these eye position effects play an important role in making coordinate transformations for visually guided movement.
