Measuring and Modulating Brain Activity The DC-STIMULATOR PLUS is a stimulator for use in scientific research that provides a stimulation with weak currents, either direct or alternating, (transcranial Electrical Stimulation; tES), within non-invasive Interventional Neurophysiology. The electrical charge and current density applied through a constant current source are far below the threshold for releasing a stimulus. Depending on the duration, the used current, the current density, and the frequency the stimulation has a modular effect on existing neuronal elements by either activating or inhibiting cortical activity. Advantages of the DC-STIMULATOR PLUS: • highest patient safety standards due to multistage monitoring of the current path, automatic termination of the stimulation, as well as continuous monitoring of the electrode impedance • intuitive menu navigation via display and four buttons • individual setting and saving of the stimulation parameters • programmable treatment schedule with limited menu access* • study mode for double-blind active and sham stimulation* • signal output for online-correction of the EEG signal during tDCS or tACS/tRNS* • extension for use of the DC-STIMULATOR PLUS in fMRI scanners*

on load impedance and features Optional features Schedule mode to set up a treatment schedule for your patient For the safe and controlled operation of the device in the absence of medical staff. The therapist sets up the parameters of the stimulation and a schedule. The patient can only start the stimulation and only at the predefined time. The patient cannot make any changes to the settings. An internal logfile records all actions for later analysis. transcranial electrical stimulation with option Trigger In Study mode for double-blind studies The study mode encodes sham and active stimulation...
