tDCS and HD-tDCS Neuronal Stimulation App Note released

Transcranial Direct Current Stimulation (tDCS) is an electrical stimulation method, which employs a direct current of value typically between 1 and 2 milliamps (ma). This method is typically oriented to neuronal stimulation in the brain. Depending on the type of electrodes used for stimulation, and their associated placement on the scalp and body, Transcranial Direct Current Stimulation (tDCS) may also be referred to as High Definition Transcranial Direct Current Stimulation (HD-tDCS).

Using BIOPAC for tDCS and HD-tDCS…

• Total arbitrary control of current wave shape is possible (DC or AC stimulation).
• Multiple STMISOLA units can be applied to the same subject.
• Electrode configurations are highly mutable.
• Exact output current applied can be sampled.
• Other physiological signals can be sampled simultaneously to look for tDCS impact on hemodynamics, sympathetic or parasympathetic nervous system.
