Behavioral selection preference and movement times. A, B, Target selection behavior for arm reaching and saccadic eye movements of animal D using the LA or RA and of animal C using only LA (different columns). Individual panels show the selection preference (expressed as BTD) in relation to the FP location. Histograms show the mean BTD (and SD) from all data collected during neural recording. Positive values indicate a leftward preference, and negative values indicate a rightward preference (missing bars indicate the absence of data). Target pair orientations (I–IV) are indicated by double arrows. C, Distribution of reach movement times (FP release to target acquisition) in the single-target and the choice task (data of both animals).
