Dose dependency of transcranial direct current stimulation: implications for neuroplasticity induction in health and disease.

The article discusses how transcranial direct current stimulation (tDCS) can have positive therapeutic effects for patients with various neurological and psychiatric conditions. It tells us how non-linear dose-response relationship for tDCS is investigated and how tDCS effects are being made in the combination of transcranial magnetic stimulation and tDCS with neuroimaging modalities such as functional magnetic resonance imaging, positron emission tomography and electroencephalography.
