gt; 1KHz) that temporally interfere at the target area deep in the brain, enabling modulation of deep brain structures. Recent results show the ability of tTIS to modulate striatal activity (Wessel et al., 2023). Cerebellum plays extensive role in cognitive processes. In older adulthood, cerebellum's connectivity with striatum is disrupted (Hausman et al., 2019). We further investigated possible interactions of cerebellar TMS with striatal TIS.
