No study has systematically tested which coil design can effectively trigger a cerebellar response with the least discomfort. OBJECTIVE: To determine the relationship between perceived discomfort and effectiveness of cerebellar stimulation using different coils: MagStim (70 mm, 110 mm-coated, 110-uncoated), MagVenture and Deymed. METHODS: Using the cerebellar-brain inhibition (CBI) protocol, we conducted a CBI recruitment curve with respect to each participant's maximum tolerated-stimulus intensity (MTI) to assess how effective each coil was at activating the cerebellum. RESULTS: Only the Deymed double-cone coil elicited CBI at low intensities (-20\% MTI). At the MTI, the MagStim (110 mm coated/uncoated) and Deymed coils produced reliable CBI, whereas no CBI was found with the MagVenture coil. CONCLUSION: s: The Deymed double-cone coil was most effective at cerebellar stimulation at tolerable intensities. These results can guide coil selection and stimulation parameters when designing cerebellar TMS studies.}, url = {https://doi.org/10.1016/j.brs.2019.09.005}, author = {Spampinato, D and Ib{\'a}{\~n}ez, J and Spanoudakis, M and Hammond, P and Rothwell, JC} }
