Abstract

Resting EEG during open and dosed eyes and subsequent mood ratings were obtained from 15 Ecstasy users and 14 Ecstasy-naive controls. Absolute spectral power on the scalp, and the three-dimensional, intracerebral distribution of neuroelectric activity using low resolution brain electromagnetic tomography (LORETA) were computed. LORETA revealed global increases of theta, alpha I and beta2/3 power during eyes open in Ecstasy users, and spectral analyses revealed a right-posterior increase of alpha2 power (confirmed by LORETA) and increased beta band activity during open eyes. Ecstasy users had higher levels of stare depressiveness, emotional excitability and a trend-level increase in state anxiety. The observed differences may be related to regular exposure to Ecstasy or other illicit drugs,or may be pre-existing. NeuroReport 11:157-162 (C) 2000 Lippincott Williams & Wilkins.
