According to recent clinical studies effectiveness of this mode of treatment in the central pain has been proved. This article reports the first case of a patient with the thalamic syndrome treated with MCS in the Clinical Department of Neurosurgery in Military Clinical Hospital in Bydgoszcz. The procedure of implantation was performed with the guidance of a frameless neuronavigation system which served for localization of the precentral gyrus.
