dlPFC gamma power predicts the precision of spatial memory retrieval. (A) Time course of gamma power in the dlPFC. Stimulus onset is at time 0, and the retrieval window (0.25–1 s poststimulus onset) is shaded in gray. Dotted gray horizontal lines indicate time points where there are significant correlations between gamma power and error (P < 0.05, cluster-corrected). Solid gray horizontal lines indicate time points where there are significant correlations between gamma power and precision (excluding the guess condition; P < 0.05, cluster-corrected). Colored shaded regions indicate SEM. (B) Mean gamma power over the retrieval window for high-precision, low-precision, and guess conditions. (C) Mean CA1-to-dlPFC Granger prediction values for each condition. Asterisks indicate significantly greater CA1-to-dlPFC directionality for high-precision vs. guess trials as determined by permutation testing (P < 0.05).
