Abstract:

Motion vision can be broadly subdivided into two systems one that codes for self-generated optic flow, and one that codes for objects that move independently of the remaining visual surround. Whereas the neuronal and behavioral algorithms underlying the detection of wide- field optic flow have been relatively well described, to the point where individual neurons of the input pathway can now be genetically silenced or activated Borst, 2011, the mechanisms underlying target detection and pursuit are much less well understood. We have investigated this topic, and here summarize the proposed goals and the achievements outputs in the form of manuscripts. Goal 1 and 2 We have identified target sensitivity amongst descending neurons in killer flies, goggle flies robber flies and hoverflies. We have investigated through extracellular electrophysiology the responses to moving targets by descending neurons in these dipterans, to determine what information is extracted and how this information is encoded.
