Figure 7.

Object-induced intersaccadic response changes of a LWC with a preferred direction from back-to-front plotted along the flight trajectory of the replayed ego-perspective flight sequence (compare to Figure 2A). This example indicates the difference between the no-landmark condition [condition 1] and the homogeneous landmark condition [condition 2]. Red circles denote landmarks (LM) and the gray circle the see-through feeder (F). The color-coded dots represent the position of the bee in the middle of each intersaccade; the corresponding line shows the direction of view. Warm colors indicate response increments, and cold colors response decrements induced by objects in the receptive field of the cell. The gray triangles attached to each dot illustrate the typical horizontal extent of the receptive field of the analyzed cells (n = 11). (A) Overview on entire learning flight. (B) Enlarged view on the intersaccades during the beginning of the learning flight. For sake of clarity the receptive field areas are not indicated for intersaccades 1–9.
