  1. Influence of test performance and age on mean amplitude of the hippocampal sources (repeated measurement ANCOVA, factor hemisphere). Digit Symbol = Digit Symbol subtest of the German version of the Wechsler Adult Intelligence Scale; Digit Span = Digit Span subtest of the German version of the Wechsler Adult Intelligence Scale; Benton-corr = correct answers of the Benton Visual Retention Test (revised form); VF = Sum score verbal fluency (semantic and phonemic) of the German version of the CERAD-NP-Plus test battery; WLL = Subtest Word List-Learning of the German version of the CERAD-NP-Plus test battery; WLDR = Subtest Word List-Delayed Recall of the German version of the CERAD-NP-Plus test battery; WLR = Subtest Word List-Recognition of the German version of the CERAD-NP-Plus test battery; FR = Subtest Figure Recall of the German version of the CERAD-NP-Plus test battery; TMT-A = Trail Making Test - Version A; TMT-B = Trail Making Test - Version B
