An interesting 100 milliseconds in which to examine vision and
attention Vision Sciences Lab, Harvard University Although we
perceive the world as stable, visual information is displaced on
the retina each time the eyes move. Neurophysiological studies
have revealed shifts in receptive fields throughout
retinotopically-organized visual areas that anticipate each eye
movement by as much as 100ms. This means that during this brief
interval before an eye movement, two retinotopic maps exist
simultaneously: One based on incoming visual input, and one
based on predicted, post-saccadic visual input. I will describe
some recent and ongoing studies probing the visual experience of
human observers at this moment in time, and speculate about the
function of this remapping process.
