TDCS transcranial electrical stimulator

As early as the 11th century, people began to try to use electricity to treat diseases, with the development of understanding of transcranial direct current stimulation technology gradually mature. In 1998, Prior et al. found that weak transcranial direct current stimulation can cause biphasic and polarity-dependent changes in the cortex. Subsequently, a study by Professor Nietzsche, a top clinical neurology expert at the University of Gottingen in Germany, confirmed this finding, thus opening the prelude to the clinical study of tDCS. So far, the clinical application of tDCS has achieved many beneficial results. Transcranial direct current stimulation technology is relatively simple to operate, high safety, quick effect, small stimulation, green therapy is easy to accept. Product principle: Transcranial direct current stimulation (transcranial direct current stimulation tDCS) is a non-invasive brain stimulation method that generates weak direct current through electrodes placed in the skull. Because it can change the activity and excitability of cortical neurons to a certain extent and induce brain function changes, as a non-invasive and efficient brain function regulation technology, it shows great potential value in the treatment of neurological diseases, mental diseases, chronic pain and other diseases. Since the occurrence of cognitive behavior is derived from the physical and chemical changes of brain excitability, the use of tDCS to improve cognitive function has rapidly become a hot field of rehabilitation medicine research in recent years.
