Relationship between reward and spatial selectivity indices in the trace-conditioning tasks. Data were combined across the space-relevant and space-irrelevant tasks, and results are shown for firing rates in the cue (left), early delay (middle), and late delay (right) time epochs. No significant correlations were observed in any of the three time epochs. Best-fit regression lines are plotted, and legend indicates the significance of reward and spatial selectivity for individual neurons.
