Scrambling sensitivity measured as the ratio of the performance on the scrambled and natural image discrimination tasks (Fig. 5), subtracted from 1. Included are scrambling sensitivity estimates based on the performance of the linear classifier analysis including the neurons recorded from both subjects and when spikes were counted in a 218 ms window (the duration of each stimulus) and for matched numbers of neurons (Fig. 5c), results for numbers of neurons adjusted for matched performance for natural images (Fig. 5e), linear classifier performance for subjects 1 and 2 individually, the correlation-based classifier, normalized Euclidean distance metric, and the linear classifier analysis when spikes were counted in 25, 50, and 100 ms windows.
