Specific Contributions of Ventromedial, Anterior Cingulate, and Lateral Prefrontal Cortex for Attentional Selection and Stimulus Valuation

Figure 3

Example spike rasters.

(A,B) The top panels show the semi-inflated medial (A) and lateral (B) view of the macaque fronto-cingulate cortex, with a white symbol indicating the site of two example neurons. (C) Attention-cue aligned spike raster across trials (top), spike density functions (middle), and ROC time course (bottom) for the example neuron from (A). The grey shading of the spike raster shows time epochs with identical visual stimulation, excluding contamination from the color onset of the peripheral grating stimuli (before cue onset) and any stimulus change occurring jittered in time after attention cue onset (see text for details). Color denotes spatial attention to the contralateral (red) and ipsilateral (blue) stimulus. Error bars denote SEM. Grey shading of the ROC time course highlight statistically significant time epochs based on permutation statistic on centered ±0.15 s windows. (D) Same format as (C), but for the example neuron in (B).
