Symposium (S6): Non-retinotopic Bases of Visual Perception

Wednesday 28 August 2013, 09:00-11:00, Borgward
Organizer: H Ogmen
Neighboring points in the environment are mapped through the optics of the eyes on neighboring points in the retina. This retinotopic organization is preserved in early visual areas. Retinotopic representations and retinotopically localized receptive-fields have been two fundamental pillars upon which most theoretical accounts of visual perception are built. Yet, due to the movements of the observer and those of the objects in the environment, retinotopic representations are highly unstable and blurred and thus fail to explain the stability and clarity of our perception. A fundamental question in vision science is to understand how retinotopic representations are transformed into non-retinotopic representations in order to synthesize the clarity and stability that underlies our perceptual experience. The symposium is motivated by the recent developments, both in terms of experimental paradigms and theoretical concepts, that provide novel perspectives to this fundamental question. The aims of the symposium are (i) to expose the field in a relatively comprehensive and coherent manner to the broader vision community and (ii) to promote a fruitful exchange of ideas from empirical findings to theoretical concepts. We expect our proposed symposium to lead to a synthesis of the current state-of-the-art of the field and chart directions for future research.
