DC-STIMULATOR MC Measuring and Modulating Brain Activity Programmable, multi-channel direct, alternating and random noise current stimulator The DC-STIMULATOR MC is a stimulator for use in scientific research that provides a stimulation using weak direct or alternating current (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. The multi-channel DC-STIMULATOR MC allows computer-controlled, full-band stimulation from independent electrical sources using any desired signal type in the range of 0 - 1,000 Hz and currents of between 50-4,000 μA with a freely adjustable phase. Furthermore, the DC-STIMULATOR MC can be used during functional magnetic resonance imaging (fMRI) and, in addition, can be combined with the NEURO PRAX® TMS/tES allowing full-band DC-EEG to be recorded during multi-channel tES. Areas of Application/Treatments Research, hospitals and surgeries: controlled, monitored and simultaneous tDCS/tACS/tRNS stimulation or sham stimulation of patient groups, multichannel tDCS/tACS/tRNS stimulation software-controlled, multi-channel stimulation of selected regions of the brain and validation of tES with the help of functional magnetic resonance imaging (fMRI) development and evaluation of user-specific stimulation sequences
