Hippocampal neuronal ensembles properties representation in 2D coordinates in normal conditions and at different time points after acute stress. a Total representation of the neuronal ensembles state in different experimental time points. PCA coordinates for baseline and b right after acute stress state (baseline (n = 15) vs stress (n = 3): X: p = 0.0054; Y: p = 0.3495, Student’s t-test). c 3 h post acute stress modeling (baseline (n = 15) vs 3 h (n = 3): X: p = 0.0447; Y: p = 0.0139, Student’s t-test for both). d 10 days after stress modeling (baseline (n = 15) vs 10 days (n = 3): X: p = 0.9020; Y: p = 0.5656, Student’s t-test). ns-non-significant; *: p < 0.05; **: p < 0.01. All the data presented as mean ± SEM
