title: [Experimental studies on changes in cerebral bioelectrical activity during combined exposure to benzene and tobacco smoke].
abstract: Four persons of average age--25 years, put in exposure chamber, were subject to single and combined effect of benzene, in the limits of MAC and tobacco smoking for a period of 5 days. An examination of the cerebral bioelectric activity was performed by EEG at the beginning and the end of each experiment. Functional changes in the EEG were established expressing disorganization and depression of the basic rhythm, increase of the number of theta waves and weakened reaction in the hyperventilation activity. These changes are explained with the increased excitability of the CNS.
