A number of authors (Hassler, Riechert, Mundinger, Umbach, Ganglberger 1960, Jung, Hassler 1960, Tóth 1968) have studied the problem how tremor activity was influenced by stimulation of the thalamus and pallidum. The results have shown that this stimulation may evoke, arrest or modify tremor activity. Many investigators (Guiot, Hardy, Albe-Fessard 1962, Jasper 1966, Hardy 1966) tried to find the correlation between thalamic function and tremor activity. Considering that we have found earlier that stimulation of the dentate nucleus may also evoke or modify the tremor (Tóth 1961, Tóth 1968), we suggest that the activity of a common basic structure may underlie this effect. In our opinion this basic structure is to a certain extent independent from the stimulated areas in fact it can be approached from different places with a more or less similar effect. Trying to find a possible explanation we studied this problem in patients with implanted electrodes.
