Differences in firing rates between preferred and nonpreferred categories

Sample (Hz)Delay (Hz)Test (Hz)
LIP2.96 ± 0.402.78 ± 0.400.84 ± 0.14
MIP0.93 ± 0.151.39 ± 0.200.34 ± 0.04
  • Preferred categories of neurons were determined for each analysis epoch, after which the mean difference in firing rate between preferred and nonpreferred categories was calculated. Only category-selective cells (see Materials and Methods) are included in the analysis.
