How it works

Transcranial direct current stimulation works by sending constant, low direct current through the electrodes.

Changes neuronal excitability, which can lead to changes in brain function.

What currents are we using?

Max. accepted tDCS current:

2 mA

For comparison, electroconvulsive

therapy involves a current of

600-900 mA

Current direction

Anodal (positive) stimulation increases the neuronal excitability of the targeted area

Cathodal (negative) stimulation decreases neuronal excitability
