Neuronal activity in BLA is correlated with social decisions. (A) Time course of decision signaling, with activity separately aligned to the onset of targets (Left), the acquisition of a choice target (Center), and the onset of reward (Right). Results stem from a sliding-window logistic regression against the type of decision for that trial. Prosocial decisions were those resulting in Other or Both rewards, and antisocial decisions were those resulting in Self or Neither rewards. Plotted are the percent of neurons for which the decision term in the regression reached statistical significance for each 400-ms window centered on the time point indicated in the abscissa. (B) The relationship between the behavioral preference indices and the neuronal preference indices. Each data point represents the neuronal preference index of a neuron and the behavioral preference index from the session in which the neuronal data were collected. Shown are the two high reward value conditions (70%, 90% of max mL) for Self:Both (Left) and Other:Neither (Right) decisions. Data points that lie precisely at the extremities (−1 and 1) are jittered for the display. Outcomes of a linear regression are indicated on the plots.
