BCI & Prosthetic Development

We record from and stimulate both the peripheral and central nervous systems in both primates and humans. Ripple’s ecosystem allows us to easily interface with all these systems with minimal development. This allows us to spend more time on the science and less on getting experiments working.

Epilepsy Monitoring Unit Research

Ripple records and stimulates in parallel with the clinical system, from the same depth electrodes, without interrupting clinical care.

  • Parallel macro recording and stimulation

  • Microelectrodes from depth electrodes

  • Flexible, closed-loop stimulation

  • Works with your clinical system

How researchers use Ripple

Five macro-contact channels recorded at 7.5 kS/s, filtered above 0.1 Hz, over 15 seconds
Macro contacts · 7.5 kS/s · >0.1 Hz
Three microwire channels recorded at 30 kS/s, band-pass filtered 300–3000 Hz, showing spiking activity
Microwires · 30 kS/s · 300–3000 Hz

Research in parallel with clinical monitoring

Clinical adapters connect the Summit in parallel with the clinical EEG system, so research recording and stimulation run on the macro contacts while clinical monitoring continues. Microwires on micro-macro depth electrodes connect to Ripple front ends for single-unit and high-frequency recording.

Hardware configuration

Explorer Summit connected to an Analog + Digital I/O module, two microelectrode front ends, and four clinical adapters with macro front ends
  1. Explorer Summit Research recording and stimulation
  2. Clinical adapters with macro front ends Macro or Macro2+stim front ends, in parallel with the clinical system on the macro contacts
  3. Microelectrode front ends Micro2 or Micro3 (or the +stim versions): record and stimulate on microelectrodes, connected directly in the headwrap
  4. Analog + Digital I/O Synchronize with clinical and behavioral events

Intraoperative Monitoring Research

Run research in the operating room alongside the existing intraoperative monitoring equipment, without disrupting the clinical workflow.

  • Connects in parallel

  • Clinical workflow preserved

  • Same channels, minimal noise

  • Quick connect and disconnect

How researchers use Ripple

Research alongside clinical monitoring

A clinical adapter connects the Summit in parallel with the clinical monitoring system, giving researchers access to the same electrode channels while the clinical setup and workflow stay unchanged.

Illustration: the patient’s electrodes connect through a clinical adapter to both the clinical monitoring system and the Explorer Summit mounted on the clinical cart
  1. Explorer Summit Research recording and stimulation
  2. Clinical adapter Splits the macro channels between the clinical system and Ripple
  3. Clinical monitoring system Unchanged clinical setup
  4. Micro interface Records from microelectrodes, connected at the patient’s head
