Description

The DSI-24 is a research-grade wireless dry electrode EEG headset designed for rapid application of 21 sensors at locations corresponding to the 10-20 International System. The DSI-24’s practicality, portability, and high signal quality opens the door to taking numerous applications that were previously limited to lab environments to more naturalistic settings. Such applications include:

  • Neurofeedback
  • Neuroergonomics
  • Neuroeconomics / Neuromarketing
  • Augmented Cognition
  • Brain-Computer Interfaces
  • Biometrics
  • Cognitive Stress or Workload Monitoring
  • Psychological Research
  • Sports Peak Performance Training
