Model validation of receptive field analysis.

Adaptation index (AI) in surround strength and center latency for different non-adapting control models. Columns labeled “mean,” “std,” and “skew” show the mean, standard deviation, and skewness of the adaptation indices for the indicated analysis; columns labeled “p” show the from of each distribution against the null hypothesis of zero mean. Standard model: Surround radii (relative to center radii) had mean 2 and standard deviation 0.3; surround weights (relative to center weights) had mean 1 and standard deviation 0.1. Small surround weight: Surround weights had mean 0.5; all other parameters were the same as in the standard model. Large surround weight: Surround weights had mean 2. Small surround radius: Surround radii had mean 1. Large surround radius: Surround radii had mean 3.
