English: Brain-imaging data from two patients with dissociative amnesia [116]. Patients 1 (A) and 2 (B) viewed images of faces and decided whether they recognised them from their life. Images were either strangers (novel), faces they knew, from outside the window of amnesia (identifiable faces) or faces they knew from within the amnesic window (unidentifiable faces). (Ai) and (Bi) depict brain areas that are more active for unidentifiable faces than for identifiable faces (right dorsolateral prefrontal cortex). (Aii) and (Bii) depict brain areas that are less active for unidentifiable faces (hippocampus).
