Abstract

This paper is the last in a series of three investigating the role of cholinergic mechanisms in the auditory system by assessing the acute effects ofnicotine, an acetylcholinomimetic drug, on aggregate responses within the auditory pathway. In a single-blind procedure, auditory responses were obtained from 20 normal-hearing, non-smokers (10 male) under two conditions (nicotine, placebo). The effects of nicotine on long-latency responses of the auditory system and on electroencephalograms are described in this paper. Results indicated that transdermal administration of nicotine to non-smokerssignificantly affects the afferent and efferent transmission of acoustic information, as well as enhancing cortical activation. Long-latency responseamplitudes and electroencephalogram activity (dominant power and frequencies) were altered by acute doses of transdermal nicotine. (C) 2001 Elsevier Science B.V.
