Data are presented for each participant with amnesia, followed by amnesic (Amn) group means and healthy normal comparison (NC) group means (and standard deviations). Abbreviations: Age, years; Hand, handedness (+100=fully right handed, -100=fully left handed); Edu., education, years; Eti., Etiology; Anoxia/An., anoxic/ischemic episode, SE, status epilepticus, HSE, herpes simplex encephalitis; Chr., Chronicity, years since injury; FSIQ, WAIS 3/4 full-scale IQ; VIQ, verbal IQ; PIQ, performance IQ; DS, digit span; GMI, WMS-III general memory index; AVLT, Rey Auditory Verbal Learning Task, trial 5/30-min. delay; CFT, Complex Figure Task copy/recall; COWA, Controlled Oral Word Association task; HcV, bilateral hippocampal volumes per Allen et al. (2006). Volumes expressed in Studentized residuals vs. normative expectations:

^*from Allen et al.; ≫, near-complete bilateral hippocampal lesion; NA, no volume available due to contraindications for MRI.
