Spatial updating and the maintenance of visual constancy Free live chat halifax
The role of alpha oscillations in deriving and maintaining spatial relations in working memory. Object working memory performance depends on microstructure of the frontal-occipital fasciculus. Path integration performance was measured by calculating the distance and angular deviation from the participant’s return point relative to the starting point.Gait parameters for the unguided walk were also recorded. Flexible working memory representation of the relationship between an object and its location as revealed by interactions with attention.

With each eye movement, a new image is presented to the brain, yet our perception is that the world remains stable.This phenomenon, termed spatial constancy, depends on a convergence of information about our eye movements with sensory information from the visual system.

Here we describe two experiments designed to gain a greater understanding of spatial updating in the primate brain.
First, we hypothesized that spatial updating would be equally robust throughout the visual field.
