Correlations of cell-firing between the haptic-choice period and the cue period in the visuo-haptic task. (D1) Difference between average firing frequencies elicited by the two objects at the tactile choice; and (D2) difference in average firing to the two visual stimuli at the cue period. (A) Correlation calculated in 16 cells, showing significant object-selective reaction at choice. (B) Correlation in 63 nonselective cells. The differential cells, but not the nondifferential cells, show significant correlation (P < 0.01).
