Towards Personalized Neuromodulation

Simultaneous HD tES & HD EEG

As one of the most exciting advances in the field of brain research, there is a surge of interest in combining HD EEG with multi-channel transcranial electrical stimulation for non-invasive neuromodulation. Experimentally, this technique is used to modulate the plasticity of the brain to understand the brain connectivity, network dynamics, and the effects on cognitive performance.

Powerful yet easy to use, the Quest HD+Stim provides an elegant solution for your neuromodulation research. Extensive software APIs and robust on-board processing give you the freedom to experiment with novel waveforms and modulate experimental stimuli based on your subject’s behavioral and/or electrophysiological responses.

The Quest HD+Stim can target specific cortical regions for stimulation and simultaneously record up to 256 channels of EEG while utilizing the same hardware, electrode caps, and software platform.

 Highlights

  • Flexible stimulation – Unlike many commercially available products, the Quest HD+Stim is not limited to simple waveforms. Stimulation parameters can be updated every 33us, making truly arbitrary waveforms possible.
  • Real-time, closed-loop control – Low latency, custom stimulation paradigms can be programmed with unique triggers and controlled in real-time with comprehensive MATLAB and Python APIs.
  • Multi-modal – Record HD EEG & stimulate with HD tES in a single hardware and software platform. Easily synchronize analog and digital inputs and outputs from external devices with neural data.
  • Programmable montage – Enables advanced investigations with the flexibility to select multiple anodal/cathodal pairs simultaneously and change locations over time.
