Our results suggest that FEF pursuit neurons issue gaze or eye movement commands during gaze-pursuit and that the head-pursuit related modulation primarily reflects reafferent signals resulting from head-pursuit related
His hefty face commands my gaze, and his jacket button strains against his overfed gut.
It must be noted that our results only argue against the presence of head tracking commands when gaze was intentionally held steady.
As though the years had melted away, the crew of the Strega stood as one and followed Mr. DuPont's command, gazing into the distance.
The dataset was developed in the vein of the MAMEM project that aims to endow people with motor disabilities with the ability to edit and author multimedia content through mental commands and gaze activity.
Graham was a dancer, and Ms. Wilson is a singer, but for both women, commanding a room could be as easy as standing there and gazing into space.
A fundamental question in sensorimotor control concerns the transformation of spatial signals from the retina into eye and head motor commands required for accurate gaze shifts.
Saccade neurons in the frontal eye fields (FEF) are thought to signal both rapid eye movement commands and rapid head movement commands for head-free gaze shifts (Tu and Keating 2000; Knight and Fuchs 2006; however, Chen 2006).
Specifically, we have shown that, in the temporal gap between its visual and movement responses, the FEF (in conjunction with its network connections) transforms the location of visual targets into gaze movement commands, both at the cell population level and at the single-neuron level.
There are 2 competing hypotheses (for a review, see Chen 2006); 1) the brain issues an integrated gaze command that is then decomposed into separate eye and head commands; and 2) the brain issues independent eye and head commands at all levels.
As described in the Introduction, there have been 2 competing hypotheses for the neural mechanisms of the eye-head coordination; one proposes an integrated gaze command driving both eye and head movements, and the other proposes independent eye and head commands together with different coordinating mechanisms such as vestibular feedback (for reviews, see Chen 2006; Leigh and Zee 2006).
