Modeling spatial contrast sensitivity in responses of primate retinal ganglion cells to natural movies
Fig 4
Evaluation of model performance by cell type.
A: Responses of sample cells from each of the four cell classes in Fig 1A to 3 s segments of test stimuli (gray) for white noise (left column) and naturalistic movie (right column), together with the predictions from the LN model (orange) and the SC model (blue). The numbers above each plot show the Pearson’s correlation coefficients between model prediction and cell response. B: Comparison of correlation coefficients for the SC model (rSC) and the LN model (rLN) for each cell in the four cell classes (colors corresponding to the labels in A) under spatiotemporal white noise (top row) and naturalistic movie (bottom row). The average correlation coefficients and
are shown next to the corresponding axes. C: Relative improvement in model performance (
) under white noise (top row) and naturalistic movies (bottom row) for each cell versus receptive-field size (left) and the obtained LSC weight w (right). Colors indicate cell class as in B.
