Title

The avian visual wulst: Functional analogue to the primary visual cortex?

Abstract

Avians have visual capabilities that often exceed that of humans and exhibit a wide variety of complex visually guided behaviors. Despite the widespread application of the pigeon model in the study of high-order visual cognition, basic understanding of its visual processing mechanisms is lacking. Based mainly upon anatomical correspondences, the pigeon visual wulst is widely assumed to be functionally analogous to the mammalian primary visual cortex. In this presentation, results acquired by voltage sensitive dye imaging together with electrophysiology will reveal the exceptional functional organization of the pigeon visual wulst for the first time, and allow for comparison to the mammalian visual system.
