Figure 4. Temporal adaptive fields during rapidly changing contrast.

Figure 4

(A) A Gaussian white noise stimulus with a contrast that changed randomly every 0.5 s drawn from a uniform distribution between 0 and 35 % contrast. (B) Example temporal adaptive fields, calculated as the spike triggered average of the contrast. (C) Average temporal adaptive fields for ganglion cells (left), and the output of the AF model from Figure 2 (right). In the data figure, the width of the lines indicates the s.e.m. The abscissa begins at 0.5 s to highlight slower changes due to changing contrast. All filters are normalized in amplitude to have the same rms value.
