Orientation selectivity index (OSI) histograms of SFA units trained with different types of stimuli.

A Training with pink noise images that were translated only. B Training with pink noise images that were rotated and translated. C OSI distribution of the Gabor-QFP model. D Training with retinal wave image sequences. Histograms in A, B, and D were obtained by pooling OSI values from the first 50 SFA units of 10 simulation runs with identical parameters for the training input generation.
