Data are estimated intended damage (in percent of normal) to the ammon fields (CA1, CA2, and CA3), the dentate gyrus and subicular complex. Total refers to average of all five hippocampal regions. Note that for Gracie, percent of damage included extent of hypersignals found after both the first and second surgical procedures. Abbreviations: L, percent damage to the left hemisphere; R, percent damage to the right hemisphere; Avg, average of L and R, W = (L× R)/100 (weighted index as defined by Hodos and Bobko, 1984).
