INTRODUCTION The centrum medianum- parafascicular complex of the human thalamus has a critical influence on cortical activity and significantly influences somatosensory function, arousal, and attention. In addition to its cortical connections, this region of the intralaminar thalamic nuclei is also connected to motor areas of the basal ganglia and the brain(More)
The use of event-related fMRI makes it possible to investigate spatio-temporal dynamics of cortical and subcortical human brain structures activity during voluntary movement performance in response to presentation of relevant verbal stimuli. The results of the study showed that voluntary movement was associated with higher contralateral brain activation in(More)
Neuronal activity of 50 neurons in nonspecific (Rt, MD) and relay (Voi, Voa) thalamic nuclei was analyzed. Data were obtained by microelectrode technique during 14 stereotactic operations in patients with spasmodic torticollis. Application of Poincare maps and Gap-statistics allowed to reveal 3 main patterns of neuronal activity: irregular single spikes,(More)
Unit activity of 50 neurons of the nonspecific (Rt and MD) and relay (Voi and Voa) thalamic nuclei was recorded extracellularly during 14 stereotactic surgeries in spasmodic torticollis patients by a microelectrode technique. An analysis with Poincare maps and gap statistics revealed three main neuronal activity patterns: irregular single spikes,(More)
