neuroConn DC-Stimulator PLUS

The neuroConn DC-Stimulator PLUS is one of the most well-established tES devices available, used in an extensive list of publications. In addition to standard features such as microprocessor-controlled constant current source, it also includes a range of advanced optional features such as double-blind sham control, analogue signal control, real time signal output, and MRI compatibility. The range of options available make the device highly configurable and suitable for a diverse array of applications.

The stimulator meets the highest safety standards thanks to multistage monitoring of the current path using both hardware and software. By means of continuously monitoring electrode impedance, the stimulator is able to accurately maintain the user-defined current amplitude while also automatically detecting if there is insufficient contact with the skin. It will automatically terminate stimulation to ensure subject safety.

The DC-Stimulator PLUS is not a medical device according to MDD93/42 EEC. The device is intended strictly for neuroscientific research.

STUDY MODE FOR SHAM STIMULATION

For double-blind sham stimulation control, remember to add the Study Mode option to your system. This option allows the user to select a pre-defined stimulation protocol and depending on the 5-digit code entered by the operator, the current delivered will either follow the active stimulation waveform shape, or a pseudo stimulation output. In both cases, the stimulator display will show the same information during real and sham stimulation.

MRI-COMPATIBLE OPTION

An MRI-compatible upgrade is available for this system, which can be included at the time of purchase, or retrospectively added to your DC-Stimulator PLUS. The 'DC-Stimulator MR' is the most extensively used device for combined tES-MRI studies, due to its reliability in delivering artefact free stimulation during fMRI. It is suitable for use with 1.5T and 3T MRI scanners.

EEG COMPATIBILITY

With the addition of one of three 'Signal Output' options, the DC-Stimulator PLUS offers is well suited to integration with EEG.

This features allows the stimulation waveform (amplitude, frequency, shape etc.) to be streamed directly to an EEG system, or other recording devices, in the form of an analogue signal. The recorded stimulation signal can then be used for online or offline artefact correction of the EEG data.

The 'Signal Output' option can also be useful in applications where the stimulator output needs to be monitored by an external device; for example, to synchronise the onset of visual or other stimuli.

EXTERNAL STIMULATION CONTROL

Remote, online modulation of stimulation parameters is available with the addition of an analogue input 'Remote Option'. This is particularly useful for research applications where time-locked, synchronised and/or varying stimulation parameters are required; for example tES-EEG applications and dual-site tACS applications.
