Speaker: Stephanie Rossit (Glasgow Caledonian University)
Topic: "The neural basis of visuomotor control and its implications for rehabilitation"

Abstract: A prominent model of vision has emphasized dissociations between the ventral and dorsal visual streams specialized for perception and action. However, in this talk I will argue that not all actions depend solely on dorsal or even ventral visual stream processing. In particular, I will present fMRI and lesion-symptom mapping data suggesting that while target-directed actions depend on regions located within the dorsal visual stream, indirect actions (such as reaching to a remembered location) depend on temporal brain regions not currently encompassed by the perception and action model. In addition, I will present data from a rehabilitation trial using action feedback to improve left visual neglect, a severe syndrome classically characterized by a loss of awareness of the left side of space.
