Dissociated neocortical pattern separation and source memory signals. Activity in the right PRC (A) was greater for correct rejections, consistent with a pattern separation signal. Activity in the right PHC (B) and bilateral angular gyrus (C,F) was greater for correct source judgments, consistent with a source memory signal. Activity in the left PHC (E) showed a response profile that was not consistent with predicted pattern separation or source memory signals or an interaction between the two. When target hits were included in the analysis, an effect of both item memory and source was observed in this region, with increased activity for LCR and for incorrect source judgments. Dotted rectangle represents conditions that were included in the two-way ANOVA. Activity in the left PRC is also presented (D). Foil correct rejections were used as baseline. Error bars indicate SEM.
