Ripple Neuromed Human NeuroPhysiology

Concurrent EEG with Neuro Stimulation

Research can take you anywhere.  Our Ripple range ensures you are always prepared with a full-featured multimodal EEG, ERP, and EMG solution that is just as capable inside the lab as it is on the road. Coupled with our unique active Front End mounted on the Explorer electrode caps the Quest HD offers the noise immunity of active electrodes while maintaining the robustness and cost effectiveness of passive electrodes. The Quest HD allows for true high-density recordings up to 512 channels, with 24-bit resolution and sampling rate of 7.5 kHz, and is optimized for real-time streaming.

Concurrent EEG with Neuro Stimulation

The Explorer Summit


Ripple Neuromed’s Summit processor provides up to 512 channels of simultaneous recording and stimulation that can fit in the palm of your hand.

A truly modular system, the Summit can record multi-modal electrophysiological signals of uncompromising quality with specialized Front Ends. On-board processing and advanced APIs provide the flexibility for any application. Easily set up in minutes, the Summit can quickly transition between the laboratory and the operating room.

With game-changing versatility, the Summit processor can be used in the lab and the operating room as a stand-alone system or to complement existing clinical systems in the epilepsy monitoring unit. Compatible with both high impedance microelectrodes and standard clinical electrodes, you can record a full range of physiological data with one processor.

With wireless data transmission, integrated battery, and internal data storage, the Summit processor is a portable platform for advanced neurophysiology, neuromodulation, neuroprosthesis development, and brain-machine interface experiments.


  • Up to 512 channels of simultaneous stimulation and recording
  • Specialized Front Ends to optimize electrophysiological recordings
  • Onboard processing for dynamic experiments and closed-loop stimulation
