Cognionics Wireless Dry EEG Electrode Sensor Headsets

Products

8-Channel Auxiliary Input Module

  

Our mobile EEG systems are capable of interfacing to external sensors and devices through the extension module. The lightweight box is connected to the headset via a thin mini-USB style cable and can be worn on the arm or belt. Up to eight devices can be connected through the binder-5 pin connector. Currently, the AIM can be purchased with: 

  • Galvanic Skin Response sensors
  • Respiration band sensors
  • Blood Pulse sensors
  • EXG sensors (EMG, EOG, or ECG)

EEGLABBCILAB (and MATLAB)

  • EEGLAB is an interactive Matlab toolbox for processing continuous and event-related EEG, MEG and other electrophysiological data incorporating independent component analysis (ICA),time/frequency analysis, artifact rejection, event-related statistics, and several useful modes of visualization of the averaged and single-trial data. EEGLAB runs under Linux, Unix, Windows, and Mac OS X
  • Easy data importation into EEGLAB from data files produced by our acquisition software
  • Same tools can be used to load files into the MATLAB workspace

LabStreamingLayer Real-time Output

  • Open standard for streaming and synchronizing multiple data sources including EEG, events and peripherals
  • LSL outlet is directly integrated into our acquisition software and can be enabled with a single click
  • Easily build advanced, networked experimental platforms with a simple and multi-platform API

NeuroPypeTM by Qusp (www.qusp.io)

  • Comprehensive algorithm library: 100+ algorithms including advanced artifact (noise) removal, high-resolution brain mapping, advanced analytics using machine learning, and much more
  • Add your own algorithms to NeuroPype using Python and shared work flow between collaborators
  • Pipelines deploy on NeuroScale for real-time access anywhere you can connect to the Internet

OpenVibe

  • Easy-to-use, powerful graphical environment for real-time BCI research
  • Cognionics driver is built into the latest version of OpenVibe
  • Driver source code hosted by OpenVibe for further customization

Developing Custom Applications

  • Direct hardware access is possible through a Bluetooth or virtual serial port interface, depending on specific model
  • Existing users have successfully integrated Cognionics hardware with custom applications on Windows, Mac OS X and Android
  • Data output specifications available upon request

Multi-Position Dry EEG Headband

The Cognionics Multi-position Headband is a designed to be a simple, flexible dry EEG experimental platform. The system is intended for use with our research grade Miniature Wireless EEG Data Acquisition System, Flex and Drypad sensors to provide low-noise, reliable dry electrode recordings.

The headband is fully reconfigurable for different experiments and applications. Sensors can be attached and moved to any of the 12 positions along the circumference of the headband to measure signals from the frontal, occipital and temporal regions. A highly elastic fabric ensure comfort, fit across a wide variety of head sizes and provides contact pressure for the dry electrodes.

USB Wireless Trigger

 USB trigger

The USB Trigger is a compact, portable system for sending time markers wirelessly to Cognionics EEG acquisition systems. It uses the same protocol as the larger Wireless Trigger and supports many of the same features including simultaneous broadcast to multiple receivers.

The USB Trigger uses a USB virtual serial port interface using the popular FTDI chipset with drivers for Windows, Mac OS X and Linux. It is compatible with most presentation/stimulus programs capable of outputting to a serial/COM port.

Because the USB Trigger uses a USB virtual serial port interface, the timing accuracy is limited to 6 ms. If you need increased precision a TTL interface and/or greater range, please refer to the larger Wireless Trigger
