Distinguishing between slow brain potential correlates of arousal and activation on the basis of their functional role and temporal involvement during a reaction-time task, data are presented which suggest that weak electrical polarizing currents applied to the head in human subjects modify predominantly activation indicators rather than arousal ones.
Distinguiendo entre potenciales lentos cerebrales indicadores de "arousal" y "activación" sobre la base de su rol funcional y compromiso secuencial durante una tarea de tiempo de reacción se presenta datos que sugieren que corrientes polarizantes débiles aplicadas céfalicamente en sujetos humanos modificam predominantemente indicadores de "activación" más bien que de "arousal".
