SSSs among a triplet of neurons related to comparison of the stimuli are associated with firing rate modulations. The comparison of SSSs and rate modulations between correct match (red) and error match (blue) trials was selected in this example. Results of U-tests of 4 s of delay and 2 s of tone presentation are shown. (A) Firing rates of neuron 3 in correct match (red) and error match (blue) trials. (B,C) Raster plots of spikes of neuron 3 in correct match (red) and error match (blue) trials. (D) P-values of neuron 3 for a difference between rates in correct match trials and in error match trials. (E) Firing rates of neuron 4. (F,G) Raster plots of neuron 4. (H) P-values of neuron 4. (I) Firing rates of neuron 5. (J,K) Raster plots of neuron 5. (L) P-values of neuron 5. (M) Rates of the SSS among neurons 3, 4, and 5. (N–S) In copies of raster plots from (B), (C), (F), (G), (J), and (K) (black dots), SSSs are shown as green dots. (T) P-values of the SSS among neurons 3, 4, and 5. The significant SSSs among a triplet of neurons were associated with firing rate modulations of neuron 3. Additional details are presented in Figure 5 and described in Section ‘Materials and Methods’.
