Figure S8: Neural codes and classifier input

Classification performance for different IFP response definitions. The inset on the top shows the definition of the analysis windows [tb,ta] where the times are defined with respect to the image onset. A. Comparison among different IFP response definitions: total power, range and power in different frequency bands. The y axis shows the relative number of selective electrodes with respect to the values reported in the text (which correspond to the range in the [50;300) ms window. The high gamma frequency band (71 to 100 Hz) yielded a higher number of selective electrodes. B. Relative fraction of selective electrodes as a function of ta, the end time for the analysis window (for a fixed tb=50 ms). C. Relative fraction of selective electrodes as a function of tb, the start time for the analysis window (for a fixed ta=800 ms; see Supplementary Methods for details).
