TDCS. Transcranial direct current stimulation
The safe and painless application of low intensity electrical current in the cerebral cortex (commonly < 2mA) makes this technique a promising tool in human neuroscience and neurobehavioural research.
The modulation of the cerebral cortex has been the subject of many studies in the field of neuroscience in recent decades. The TDCS has shown in different brain areas that it can induce different modifications in the perceptive, cognitive and behavioural functions, as well as improve adaptive neural activity patterns, suppress maladaptive activity patterns and restore the balance of some neural networks.
The treatments with TDCS follow different administration protocols depending on the pathology to be treated, but they normally require stimulation doses of 10 to 20 minutes and from 10-12 sessions to 30 with a variable periodicity.
