Figure 2.

Figure 2.

An example of associative-pair-selective neurons. A, Neuronal activity in the pattern-to-face trials of an associative-pair-selective neuron are displayed in rasters and spike-density functions (σ = 10 ms). All graphs are aligned to the onset of the cue (left) and target (right) presentation (time 0). Differences in raster colors indicate four different paired associations; five different views are intermixed in the rasters tinted in accord with the paired associates. Dashed lines on the graphs indicate the mean firing rates during the control period (208 ms period before presentation of the cues) ± 2 SD. B, Neuronal activity in the face-to-pattern of the same neuron. The figure conventions are the same as those introduced in A. C, Summary of cue-face responses. The mean firing rates of cue-face responses to five facial views of four facial identities are coded using different colors. D, Summary of neuronal responses to cue faces (cue-face responses) in face-to-pattern trials and those to cue patterns (cue-pattern responses) in pattern-to-face trials. The panel for cue-face responses shows the mean firing rates ± SEM during the period 64–560 ms after the onset of cue presentation (cue period) for each facial identity (5 facial views are averaged in this panel). The panel for cue-pattern responses shows the mean firing rates ± SEM in the cue period for each pattern. E, ROC curve of neuronal responses to cue faces to best discriminate a particular facial identity. Of the four identities, the ROC curve with identity 1, which produced the largest AUC value, is depicted (red). Ten other ROC plots based on the surrogate data in which the relationship between stimulus and response was destroyed are also shown in blue. F, ROC curve of neuronal responses to cue faces to best discriminate a particular facial view (the +45° view). The figure conventions are the same as those introduced in E. G, ROC curve of neuronal responses to cue patterns to best discriminate a particular pattern (pattern 1). The Figure conventions are the same as those introduced in E.
