Cue-selective neurons in OFC do not generally reverse their selectivity when contingencies are reversed. Population response of neurons in OFC identified as cue-selective during learning. Average activity per neuron is shown, synchronized to odor onset, before and after reversal. The population response fails to reverse cue-selectivity. Inset scatterplot compares the cue-selectivity indices before (X-axis) and after reversal (Y-axis) for all the cue-selective neurons used to construct the population histograms. Blue and red symbols show data for “Odor 1 Selective” neurons and “Odor 2 Selective” neurons, respectively. The cue-selectivity indices show no correlation. Cue-selectivity index was defined as (frO1 − frO2)/(frO1+frO2), where fr = firing rate during cue-sampling, O1 = odor cue that predicted sucrose before reversal; O2 = odor cue that predicted quinine before reversal.
