Extended Data Fig. 8: Retrospective coding of aVEVS cells versus prospective coding in place cells.
From: Moving bar of light evokes vectorial spatial selectivity in the immobile rat hippocampus
a, (Top) A bidirectional cell responds with a latency after the stimulus goes past the angular position of the bar of light depicted by the green stripped bar. (Bottom) Population overlap is above the 45o line, indicating retrospective response. b, Same as a but for a prospective response, where the neuron responds before the stimulus arrives in the receptive field. Such prospective responses are seen in place fields during navigation in the real world, where the population overlap is maximal below the 45o line (adapted from earlier work8). Prospective coding was seen in purely visual virtual reality, but those cells encoded prospective distance, not position.
