title: [Posterior theta rhythms during waking state activity in man (author's transl)].
abstract: Telemetric recordings were made of 44 subjects divided into 4 groups according to age and occupation (35 and 50 years--skilled workers and university personel), during a period of 8 hours working activity. Short sequences of posterior theta rhythms were observed in all cases. They appear mainly during continuous work activity and diminish or disappear when work ceases. They are more frequent in the 50-year-old subjects than in those aged 35 years. They are neither pathological nor related to immaturity or emotion, and their etiology is related to visual perception and attention.
