Farran Briggs will describe a series of approaches using traditional and modern tools to explore how cortical feedback influences early visual processing. Transformations in visual signals traversing the feedforward retino-geniculo-cortical pathways are well understood, but the contribution of corticogeniculate feedback to visual perception is less clear. Through examinations of the morphology, physiology and function of corticogeniculate neurons, a new hypothesis emerges in which corticogeniculate feedback regulates the timing and precision of feedforward visual signal transmission.
