Hippocampal and frontal activation during encoding and retrieval. (A) Activation along the hippocampus longitudinal axis during encoding (red) and retrieval (blue) relative to control task (threshold, t > 8.0 for illustration). (B) Activity in the right anterior hippocampus (aHC) was stronger during encoding (P < 0.001, t₍₃₂₂₎ = 6.51), and in the right posterior hippocampus (pHC) at retrieval (P < 0.001, t₍₃₂₂₎ = 4.76). Data displayed from the peak voxels, collapsed across imaging sessions. (C). Differential recruitment of right frontal cortex during retrieval. Data displayed from the peak voxel, collapsed across imaging sessions. Ctr, control task. Vertical lines = ± Standard Error of Mean (SEM).
