Transcranial magnetic stimulation and electrical stimulation of the brain are very promising technologies， and are gradually being applied in basic research and clinical practice. This non-invasive， noninvasive targeted neural stimulation improves or restores brain function by modulating neural excitability and plasticity. Because the cerebellum has neuroanatomical and functional connections with the brain in motor coordination， association and emotion， nerve stimulation targeting the cerebellum can help with better understanding of the relationship between the cerebellum and the swallowing motor area of the brain under physiological and pathological conditions， and better study the regulation of cerebellum on the excitability of swallowing cortex and its effect on swallowing function， so as to provide a potential treatment for neurogenic swallowing disorder.
