What is the PowerMAG EEG 30?

The PowerMAG EEG 30 is MAG & More's dedicated TMS stimulator for combined TMS-EEG research. Operating at up to 30 Hz, it is specifically engineered to eliminate the artifacts that typically contaminate EEG recordings during TMS — delivering continuous, clean EEG traces without power-line noise or recharging artifacts. It is the ideal system for researchers investigating cortical oscillations, connectivity, and evoked potentials through simultaneous TMS and EEG.

Its full external control interface and compatibility with the PowerMAG View! neuronavigation system make the PowerMAG EEG 30 a powerful and versatile platform for high-quality concurrent neurophysiology.

Key Features

• EEG-Artifact-Free Stimulation: Purpose-built to enable continuous EEG recordings without power-line noise or recharging artifacts — the critical requirement for TMS-EEG research.
• 30 Hz Operating Frequency: Supports rTMS and Theta Burst Stimulation (TBS) up to 30 Hz, covering the standard range of EEG research protocols.
• Half & Full Waveforms: Both waveform types available for flexibility across research paradigms.
• Invertible Coil Current: Enables reversal of the induced current direction to precisely control the orientation of cortical activation.
• Paired-Pulse TMS (ppTMS): Supports long-interval ppTMS paradigms for probing cortical excitability via EEG.
• EMG Compatible: Supports simultaneous EMG recording for motor evoked potential measurement alongside EEG.
• Full External Control: Analog, digital, and trigger interfaces for computer-controlled stimulation and seamless synchronization with EEG acquisition systems.
• Neuronavigation Ready: Fully compatible with the PowerMAG View! 3D neuronavigation system for reproducible targeting.
