Fig. 4.

Correlations between parameters of the population coding model. (a) Peak firing rate vs full-width at half-maximum (FWHM). Each symbol indicates z-scored median parameter values for one experiment, in retro-cue (red) and control (black) conditions. Green line indicates best fitting regression line. (b) Swap frequency vs full-width at half-maximum (FWHM). (c) Peak firing rate vs swap frequency: note the strong negative correlation between these parameters. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
