4 pm – Figure-ground modulation in superior colliculus of behaving mice

Abstract
When using vision to explore the world, a visual scene needs to be segregated into behaviorally relevant blocks: objects. The process of object segregation, despite its complexity, can be performed in a fraction of a second and is seemingly effortless. Previous studies have indicated that neurons in primary visual cortex (V1) show more activity when elicited by figures compared to when elicited by a background. Further experiments have suggested that the increased response may be the result of interactions between V1 and higher visual areas. Nevertheless, recent studies also suggest that superior colliculus can modulate V1 activity via an indirect pathway. In this seminar, I will discuss unpublished results from experiments investigating the role of superior colliculus in object segregation.
