CAMELO, Sandra; ROJAS, Daniel; MEJIA, Andrés  e  CASTRO, Rafael. Using a brain control interface to record brain activity involved in attention during driving under the influence of alcohol. Divers.: Perspect. Psicol. [online]. 2015, vol.11, n.2, pp.217-233. ISSN 1794-9998.  https://doi.org/10.15332/s1794-9998.2015.0002.04.

The ingestion of alcohol has been linked to characteristic changes in EEG activity, and these changes depend on several factors. Previous research has been conducted with a variety of experimental designed, but most have focused on reporting the effect of alcohol consumption in subjects with a history of alcohol abuse, and a few have reported the effects of lower doses of alcohol. This project recorded brain activity related to attention in a driving situation with an emotiv EPOP brain control interface (BCI) device after ingestion of 0,300 g of alcohol (0,02 % BAC) or none in a pre-experiemental pre-test and post-test design with 30 college students aged 18-45. Results suggest that lower doses of alcohol change wave dynamics, reducing the amplitude of fast alpha (9-13Hz) and beta (14-30Hz) waves in frontal lobe zones involved in sustained attention in driving
