Fig. 7: Air puff selective assembly patterns.
From: Aversive stimulus-tuned responses in the CA1 of the dorsal hippocampus
a Representative assembly reactivation location – lap number raster with place (left panel) and air puff preference (right panel, from same session as example neuron on Fig. 1b). Arrowhead mark air puff locations. White dashed lines separate consecutive control and air puff (4) epochs. Assembly activation strength are normalized by the total bin count. b Summary data of the number of aAP-Pyr cells (left panel, 3 ± 1.4 vs 0.7 ± 0.9, p**=1.7 ×10−6) and weight of aAP-Pyr cells (right panel, 2.6 ± 1.1 vs 0.9 ± 0.4, p**=3.4 ×10−7) in air puff assemblies (AP-a, n = 7) and in non-air puff assemblies (nAP-a, n = 84), for testing significance Wilcoxon-Mann-Whitney test was used. c Representative air puff-assembly identified by using the whole session (left panel) or only the non-air puff epochs (right panel). Weights of simultaneously recorded units in the two assemblies arranged in descending order. aAP-Pyr cells are color coded in violet. d Similarity of a representative place (upper panel) and air puff assembly (lower panel) to a synthetic air puff assembly. Histograms correspond to similarity index distributions generated by shuffling unit IDs. Red line indicates similarity threshold (1%) and filled circles mark similarity index of the example place (red dot) and air puff assembly (violet dot). e Weight of AP-Pyr cells and non-AP-Pyr cells in air puff assemblies (n = 4 from 4 sessions) detected in pre- and post-air puff sessions on the polystyrene ball and in the non-air puff epochs of the air puff session on the disc. For testing significance 2-way repeated measures ANOVA was used. Factor A (aAP – nAP Pyrs), F(1,6) = 0,006, p = 0.94; for Factor B (Pre, Disc and Post) F(2,12) = 5.778, *p = 0.017; Interaction F(2,12) = 1,21, p = 0.33. There was no significant difference with Tukey post hoc test between Pre, Disc and Post conditions. On panels b,e box and whiskers correspond to median, quartile (25%−75%) and 10–90% range. Source data of panel b,e are provided as a Source Data file.
