The effects of transcranial direct current stimulation on the cerebellar fMRI activity

The cerebellum is essential for movement coordination and control and is involved in several pathways associated with cognitive processing. It is thought, that the cerebellum provides a predominant inhibitory tone on the primary motor cortex at rest, probably mediated through the inhibition of the dentate nucleus by cerebellar cortex Purkinje cells. It has been shown that noninvasive transcranial direct current stimulation (tDCS) can induce polarity-specific neuronal excitability changes of the cerebellar cortex and affect motor learning. In this study we wanted to investigate how tDCS influences cerebellar cort…
