title: [Use of a topographic analysis of the myoclonic activity recorded from the scalp for detection of functional disorders of the serotoninergic systems].
abstract: A study was made of 36 EEGs chosen in terms of the principle of combination in them of two elements: (1) a focus of paroxysmal activity; (2) electrophysiological correlates of myoclonus whose stem origin was not questioned. The appearance of myoclonic and paroxysmal patterns distribution on the scalp was reproduced with the aid of color pictograms. It has been discovered that the stem myoclonic activity is largely grouped around the paroxysmal one; within the limits of the anterolateral quadrant of the scalp surface, one can see a tendency toward a compact recording of the stem myoclonic and authentic paroxysmal patterns. In cases where the paroxysmal activity is in the anterotemporal focus, the proximity of the points of the recording from the scalp of the stem myoclonic and paroxysmal patterns may appear maximal. As the latter ones get detectable during recording, the myoclonic patterns play the role of their satellites (rather than coincidents). This can serve a prerequisite for ascertaining local deficiency of 5-HT during observation on the EEG of compact-grouping myoclonic phenomena recorded within the limits of one anterolateral quadrant of the scalp surface.
