English: Spatial activity of the model with 12 VCOs as noise accumulates. The left side of the video is a spatial firing rate map calculated as described in the text. The darkest blue color means no firing, and darkest red corresponds to the highest firing rate. The text over this plot indicates the variance of the cumulative noise as it builds up from 0 to 3 radians2. The right side of the video shows the same region of space but shows the overlapping activity of each VCO (colored red, green, and blue; the four VCOs of the same color are each drawn at 25% transparency) such that the cell fires when enough bands overlap and produce a white color (compare to Figure 3 in the text). The changing spatial pattern on the left is a direct result of the noise-induced movements of the individual VCO bands shown on the right.
