From: A sparse coding model of V1 produces surround suppression effects in response to natural scenes
Surround suppression effects in a sparse coding model (compare to [1, 2]and results with white noise stimuli, not shown). A. A single cell's responses to natural movies masked to 1x (top plot) and 3x (middle plot) the CRF size. The bottom bar marks frames with significant suppression (white), facilitation (black), or no significant change (gray) when the nCRF is included. B. Lifetime sparseness of each cell with 1xCRF stimulus (x-axis) and 2xCRF stimulus (y-axis). Sparsity increases with inclusion of the nCRF. C. Population average of the mean activity of each cell with increasing stimulus size.
