QUEST HD+STIM

Custom, Programmable, Transcranial Stimulation and EEG/ERP Recordings

The Explorer Quest HD+Stim

Custom, Programmable, Transcranial Stimulation and EEG/ERP Recordings

Expanding upon the full-featured recording capabilities of the Quest HD, the Quest HD+Stim provides extensive tES capabilities, including tDCS, tACS, tPCS and tRNS.

Our extensive software APIs give you the freedom to experiment with customized and novel waveforms. Modulate experimental stimuli based on your subject’s behavioral/electrophysiological responses with the powerful on-board processing of the Quest HD+Stim.

With all of the mobility and recording features of the Quest HD, the Quest HD+Stim can perform HD tES & record HD EEG in up to 256-channel configurations.

Highlights

  • All of the mobility and features of the Quest HD
  • Simultaneous transcranial stimulation and EEG/ERP

  • Closed-loop control of stimulation parameters
  • Meets safety standards for laboratory and clinical research

Up to 256 channels

of EEG recording and stimulation

7.5 kHz sampling rate

for the highest quality data

Flexible Stimulation – No limits. Arbitrary and complex waveforms.

Selectable stimulation – 256 channels with sub-millisecond switch times. Up to 16 channels of simultaneous stimulation.

REAL-TIME, CLOSED-LOOP CONTROL – PROGRAMMATIC CONTROL. REAL-TIME FEEDBACK. MATLAB & PYTHON

Multi-Modal – Record HD EEG & stimulate with HD tES in a single hardware and software platform.

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

Experimental configuration and custom stimulation paradigms can be programmed and initiated with unique triggers and controlled in real-time with comprehensive MATLAB and Python APIs.
