Extended Data Fig. 8: ESR is unaffected by temporal and spatial variations within events.
From: Hippocampal neurons represent events as transferable units of experience
a, Distribution of running time across trials for animal 197 during 18 trials; b, Coefficient of variation \(\left( {\frac{{\upsigma }}{{\mathrm{\mu }}}} \right)\) for running time among trials in n = 14 animals. c, Fixed maze elongation experiment: 4-lap-per-trial task on: Day 1: the standard maze and Day 2: the elongated maze. d—e, Example lap 1, 2, 3, and 4 preferring neurons matched across standard and elongated maze sessions. f, ESR correlations across standard and elongated maze sessions (448 cells, n = 6 mice). The proportion of cells with highly preserved ESR patterns across days (Pearson’s r > 0.6, shown in the Blue box) was significantly greater compared to shuffles. g, Spatial correlations and ESR correlations across days, during the fixed maze elongation experiment (448 cells). h, 185 out of 448 ESR cells had main spatial field not on the shared unstretched half of the maze. Within these 185 cells, 91 cells had highly preserved (Pearson’s r > 0.6) ESR patterns across days (Orange bar) significantly greater compared to shuffles (Grey bar). Blue dots: shows the proportion of cells for each individual animal. χ2 and p values are shown in the Figure.
