Non-Linear Neuronal Responses as an Emergent Property of Afferent Networks: A Case Study of the Locust Lobula Giant Movement Detector
Figure 3
Analysis of shape and texture effect on the peak firing rate relative to the Time To Contact (TTC).
(A) to (C): TTC versus the l/|v| ratio is invariant to stimulus shape and texture for the entire set of l/|v| ratios; (A) concentric squares, (B) checkerboard texture, (C) solid circular stimulus. The error bars indicate data variance; r is the correlation coefficient of the data with its linear regression.
