Poseidon is the ultimate leap in amplifier technology for brain monitoring that sets a new standard for signal quality, usability and mobility.

​Poseidon is miniature, wireless EEG/ECoG/iEEG module that enables real-time, high-fidelity brain electrical signals to be streamed to any WiFi connected device such as a laptop computer, smart phone or tablet or stored locally on a microSD card. It boasts 24-bit ADCs and extremely-high dynamic range with user-selectable filters and sampling rates. Experiment designs are no longer limited by noise and mobility issues caused by traditional EEG system wires and cables. Real-time impedance measurements provide monitoring of electrode-contact quality.

​Applications

EEG/ECoG/iEEG monitoring
Neuroscience research
Consciousness studies
Event-related potentials (ERPs)
Evoked potentials (EPs)
Sleep studies
Biofeedback
Neuromarketing
Brain-computer interfaces (BCIs)
EEG education & training
​Simultaneously with​ MRI/fMRI
  • 32 monopolar channels (EEG, ECoG)
  • Low noise (< 0.5 µVrms)
  • DC - 500 Hz
  • 24 bits @ 1 kHz or 250 HZ
  • 4 bipolar channels (ECG, EMG, EOG)
  • 3-axis accelerometer
  • Wireless and rechargeable
  • 10 / 72 hours use (Wifi / local storage)
  • Local micro SD card storage (128 GB)

  • 150 mm x 60 mm x 45
With Poseidon, high quality EEG/ECoG/iEEG & EMG/ECG signals are now possible from a device small enough to fit in the subject’s pocket. Wireless triggering provides precision event marking and synchronization with 3rd-party video or control systems. Easily switch between WiFi mode, Logger mode,or Hybrid mode. Data is stored on a 64 GB removable micro SD card and/or transmitted to a computer or smart device for viewing, analysis and storage. 
Poseidon Headbox is an innovative headbox design with a plug-in slot for Poseidon. It transforms the industry-standard, EEG headbox design to one with advanced signal-processing, WiFi connectivity and data logging. It is equipped with 40 standard touch proof jacks, reference and ground. It is compatible with EEG/ECoG/iEEG & EMG/ECG electrodes.

Poseidon Plus is similar to the Headbox except it only has 32 standard touch proof jacks, reference, and ground.

​Streamlined touchproof (safelead) interface
​WiFi & local data logging
Athena GUI Software

​Athena is Poseidon’s intuitive and powerful software that allows you to visualize and analyze data including such analyses as correlation, coherence, event related potentials, evoked responses, and event/spike- triggered averaging. Set filters to view alpha, beta, theta, delta, and gamma waves and view power spectra or spectrograms in real time.

Export data to BDF, EDF, CSV, or binary files for importing into 3rd-party applications such as MATLAB, EEGLAB, BCILAB, FieldTrip, SciPy, and EDF Browser. SDK is provided for development of real-time EEG measurement, analysis and closed-loop (BCI) applications.
