Abstract

Endogenous P300b event-related potential (ERP) and behavioral performance measures, extracted during a: visual memory Scanning task, and spectral, indices of resting electroencephalographic (EEG;) activity, were assessed in 12 healthy elderly adults before and after double-blind oral administrationof a placebo or glucose (50 mg) beverage. Glucoregulation was estimated byderiving a recovery index to categorize subjects as having: better (BR) orpoorer (PR) blood glucose recovery. Although glucoregulatory status, did not impact on EEG or task performance, PR subjects exhibited reduced P300b areas relative, to BR subjects prior to beverage administration. Glucose didnot after P300b or memory scanning performance but, regardless of glucoregulatory status, it increased the EEG power in the slow alpha frequency band. The study results suggest that peripheral glucoregulation can influence neuroelectric measures of cognition, and that the acute ingestion of glucosecan modulate central arousal processes.
