The value of social information is signaled by neurons in the macaque visual orienting system. (a) Average firing rate for 34 LIP neurons plotted against time for all trials in which the subject chose to view the image (T2) in the neuron’s response field, separated by image class. (b) Average firing rate of the population for all trials in which the subject chose to view the image (T2) in the neuron’s response field, separated by fluid value relative to the non-chosen target (T1). (c) Firing rates during the 200 ms after target onset, plotted as a function of image value (left) and as a function of difference in fluid payoff between T2 and T1 (right). Regressions were performed on all data in which the subject chose to view the image. The data in (c) were binned for display, but all regressions were performed on raw data. **p < 0.001.
