Abstract
The dorsal column nuclei, a first relay station of the somatosensory system, express coherent oscillatory activity in the 4–22 Hz frequency range at single unit, multiunit and local field potential levels. This activity appears spontaneously (33% of the cases) or, more commonly (83%), during natural sensory stimulation of the receptive field. Also, neurons synchronize their activity: the analysis of interactions between oscillatory activities, studied between neurons sharing overlapping RFs, revealed that DCN neurons displayed coherent rhythmic activity both at rest and upon peripheral stimulation of their RFs. Such oscillations are not imposed upon the dorsal column nuclei by incoming sensory afferents nor cortico-nuclear projections, which indicates that they are generated within the dorsal column nuclei.
