Non-Linear Neuronal Responses as an Emergent Property of Afferent Networks: A Case Study of the Locust Lobula Giant Movement Detector
Figure 4
Responses of the model for different approach angles of the looming stimulus.
(A) The mean number of spikes per trial is calculated for four different approach angles. At least 20 repetitions have been performed per angle/speed pair. The l/|v| ratio was varied from 10ms (circles), to 30ms (triangles) and 50ms (diamonds). (B) The difference of the TTC of peak firing rate with respect to the l/|v| ratio between a frontal approaching trajectory and one at an angle representing 75% of the visual field. Error bars indicate data variance.
