The NeuroState Cap combines eight-channel EEG with PPG and motion sensing in an adjustable wearable form. Patented electrode technology is designed to acquire EEG signals at key scalp locations, including areas covered by hair. Connected to the NeuroState app, the Cap supports cognitive training, guided Sessions, neurofeedback, brain metrics and custom activity tracking.

Measure Your State. Train Your Mind. Use It in Real Life.
NeuroState is a connected brain-sensing and cognitive training system built around the NeuroState Cap and app.
The NeuroState Cap combines eight-channel EEG with PPG and motion sensing to help you observe focus, cognitive load, heart-related signals, breathing, and movement during training and everyday activities.
With the NeuroState app, you can use NeuroState Train, guided Sessions, neurofeedback, brain metrics, and custom activity tracking to review individual sessions and compare patterns over time.
- Patented through-hair electrode technology
- Eight-channel EEG with PPG and motion sensing
- EEG-informed cognitive training
- Guided Sessions and neurofeedback
- Custom activity tracking and session comparison
- iPhone and Android compatibility
See NeuroState in Action
Go Beyond a Performance Score
The Brain Test shows how you performed across key cognitive domains. NeuroState Train gives you structured cognitive challenges. The NeuroState Cap adds another layer—real-time brain-state and body-signal data, EEG-informed training, neurofeedback, and activity tracking during the things you actually do.
Connect cognitive performance with what is happening while you train, work, practice, and prepare.
One Cap. Four Connected Ways to Use It.
Measure
See focus and cognitive-load measures alongside heart rate, HRV, breathing, and movement. Review individual sessions and observe your patterns over time.
Train
Use NeuroState Train across cognitive domains including attention, memory, processing speed, reasoning, and flexibility. With the Cap, training can incorporate cognitive-load information alongside performance.
Prepare
Use guided Sessions and neurofeedback before demanding activities, during daily check-ins, or as part of a reset or wind-down routine.
Track
Create your own activity, record your NeuroState while you do it, and compare repeated sessions over time.
Your Brain, in Context
A brain metric becomes more useful when you know what you were doing when it was recorded.
Create an activity for deep work, studying, meditation, presentation practice, creative work, or almost anything else you choose. NeuroState saves the session with that activity so you can review your metrics and compare repeated sessions over time.
Track. Repeat. Compare. Learn your patterns.
Advanced Brain Sensing, Made Practical
Eight-channel EEG, PPG, and motion sensing come together in a wearable system designed for practical everyday use.
Built by Neuroscientists. Used in Research.
NeuroState was developed by a team led by Dhiraj Jeyanandarajan, M.D., M.B.A., a board-certified neurologist with fellowship training in clinical neurophysiology. The platform draws on years of experience with EEG and neurophysiologic monitoring, with research spanning areas such as cognitive workload, attention, and simulator performance.
