Abstract：Transcranial random noise stimulation (tRNS) is a specific type of transcranial electrical stimulation technique that uses current of random frequency and amplitude to modulate neural activity. It affects brain activity and cognitive behavior through mechanisms such as stochastic resonance, and has demonstrated remarkable modulation effects in the fields of neuroscience and neuropathology, thus gaining increasing attention and application. This reviewmainly introduced tRNS’s physiological effects, implementation, and the status and development trend in modulating perception, motion, learning and memory, and psychiatric symptoms.
