DESCRIPTION:Speaker: Ann Hermundstad\nhosted by Thijs van der Plas\nAbstrac
 t: Many flexible behaviors are thought to rely on internal representations
  of an animal’s spatial relationship to its environment and of the conse
 quences of its actions in that environment. While such representations—e
 .g. of head direction and value—have been extensively studied\, how they
  are combined to guide behavior is not well understood. I will discuss how
  we are exploring these questions using a classical visual learning paradi
 gm for the fly. I’ll begin by describing a simple policy that\, when tet
 hered to an internal representation of heading\, captures structured behav
 ioral variability in this task. I’ll describe how ambiguities in the fly
 ’s visual surroundings affect its perception and\, when coupled to this 
 policy\, manifest in predictable changes in behavior. Informed by newly-re
 leased connectomic data\, I’ll then discuss how these computations might
  be carried out and combined within specific circuits in the fly’s centr
 al brain\, and how perception and action might interact to shape individua
 l differences in learning performance.
