Figure 3From: Atypical evening cortisol profile induces visual recognition memory deficit in healthy human subjectsCorrelation with evening corticosterone level and familiarity discrimination. (A) Cortisol10 pm level was negatively correlated with performance in the novel object discrimination across the whole cohort (r = -0.44, r2 = 0.19, P < 0.01, n = 44). (B) Mean (± s.e.m.) reaction time to novel stimuli. The high cortisol10 pm group were significantly slower at responding to the fourth repeated presentation of a novel object. *Significant group difference at p<0.05. (C) Mean (± s.e.m.) reaction time to familiar object stimuli. There was no significant group difference (P > 0.05). Filled bars indicate low cortisol10 pm group, and open bars indicate high cortisol10 pm group.Back to article page
