From: Neuronal baseline shifts underlying boundary setting during free recall
Content-selective baseline shifts during free recall—group results. a Median HFB amplitude in category selective electrodes was increased in a content-selective manner throughout the free recall period (two-way mixed-effects ANOVA, interaction: F(1,63) = 17.69, ***p < 0.0001). b A histogram showing HFB amplitude gain during recall across all category selective electrodes: preferred minus non-preferred category, p < 0.0001, signed-rank test. c HFB amplitude gain during early, middle and late recall stages: preferred minus non-preferred category. There was no significant difference between the three stages (p = 0.15, one-way repeated measures ANOVA). d−f Correlation between category-selectivity index (CSI) during viewing and baseline-shift selectivity during recall (all category selective electrodes: Spearman’s ρ = 0.46, p = 0.0001; intermediate visual areas: Spearman’s ρ = 0.50, p = 0.009; V1 and V2: Spearman’s ρ = −0.07, p > 0.68). In contrast to high visual areas, early visual electrodes did not show any correlation. Error bars represent SEM
