Prospective and retrospective coding in the OFC and hippocampus. A, An example of prospective coding for a cell with a place field on the start arm (SA) in the hippocampus (adapted from Ferbinteanu and Shapiro, 2003). Internal figure depicts a heat map (5 × 5 cm pixels) of the firing rate across the entire maze. External figures depict the firing rates on the two paths originating from that start arm. Units of the color bar are firing rate in hertz. B, An example of prospective coding for a cell in the OFC. The asterisk (*) indicates significantly greater activity on only the start arm between the two paths (comparison by Student's t test, p < 0.05, between two groups).
