PowerMAG SystemsThe PowerMAG LAB and PowerMAG EEG stimulators from Mag and More, GmbH are suited to a wide range of research applications.  These repetitive magnetic stimulators meet all expectations of quality and sophistication for an advanced research device.  PowerMAG systems are highly configurable, allowing us to provide a system with just the features you need, whether your application demands a lot or just a little.  We not only provide a variety of rTMS simulators with all the relevant accessories, but we also provide innovative solutions for 3D neuronavigation.

Capabilities include:

• ppTMS short interval (SI), and long interval (LI)

• Theta-Burst-Stimulation

• Quattro pulse stimulation (QPS)

• High power & high frequency protocols


The PowerMAG LAB represents the top-class in TMS stimulators. It is able to generate burst of pulses up to 100 Hz with constant intensities by recharging between pulses. It also has an impressive maximum pulse frequency of 100 Hz at 70% intensity, making this stimulating device a perfect choice for the latest stimulation protocols, such as theta burst stimulation.



The PowerMAG EEG was specially developed for the high-end research user who needs to stimulate while recording EEG concurrently. Powerful high-frequency TMS (including Theta Burst Stimulation) as well as high-precise single pulse and paired pulse protocols are available in one standalone device. In addition to the application areas above, the PowerMAG EEG systems are suitable for online TMS & EEG.

The inside diameter of adhesive ring should be about the same size as, or larger than, the diameter of the electrode contact.  The inside diameter of the adhesive ring should not be larger than the outer diameter of the electrode housing.  The outside diameter minus the center hole determines how much surface area contacts the skin, thus determining how tightly the adhesive will adhere to the skin.  Also, the outside diameter will limit how close you can place electrodes to one another and to other features, such as the eyes.

Using ActiveTwo as an example, the electrode contact on a flat-type electrode has a diameter of about 4.5 mm.  An adhesive ring with 5 mm id (center hole) would be  idea, but the 5×13 adhesives are rather expensive because they are manufactured in Europe.  We recommend using a 4×19 or a 4×12 adhesive ring.  The 4×12 is a good choice when placing the electrodes close to one another or close to the eyes for startle measurements.  The 4×19 is a good choice when you have plenty of room and the primary concern is how well the electrodes stick to the skin.
