title: [Problems of methodology when studying the relationship between EEG and behaviour: use of the technique of sedation threshold to sodium amytal (author's transl)].
abstract: The objective of the study was to clarify the relations between EEG activity and behaviour using the technique of the sedation threshold to sodium amytal. Our results show that there is no parellelism between the EEG and behavioural thresholds, more especially because, in male subjects, there is resistance to falling asleep which delays the appearance of errors in calculation. Contrary to Shagass, whose work on the sedation threshold is based on the implicit postulation of the existence of a close relationship between EEG and behaviour, our results lead to the theoretical conclusion that we must take into account a certain freedom of behavioural responses, in relation to physiological phenomena upon which they are based.
