From Spatiotemporal Tuning to Velocity Analysis
One of the authors (MW) had the privilege of working with Hisako Ikeda between 1970 and 1975, and carried out extensive single cell recording studies in the retina, LGN and visual cortex of cats. Ikeda and Wright (1976) also conducted some of the earliest studies on animal models of amblyopia, in which they looked at the effects of surgically induced squint in kittens on the responsiveness of single cells in the LGN. This work was interpreted within a framework of parallel processing streams in the visual pathways. All these issues are very much still current concerns of the Vision Research community. One of these topics, parallel processing and spatiotemporal tuning of cortical neurons is the subject of current research at Brunel University. In this work, we try to develop models and explanations of human vision, for instance, human motion perception, which are firmly rooted in physiology, and make use of fundamental neurophysiological findings in deriving explanations of human visual performance.
