What is EEG and how can it be used?

The Electroencephalogram (EEG) is a painless test that use to record brain activity. Our brain cells communicate with each other in the form of electrical signals. EEG test records all the electrical activity of brain in the form of Wavy patterns

What is the need to EEG (Electroencephalogram)?

The EEG data is recorded and analyzed in terms of Wavy lines. Electroencephalogram test is carried out to detect different types of brain disorders given here.

  • Brain injury
  • Brain tumor
  • Disease of dementia or Alzheimer
  • Brain dysfunction
  • Seizures
  • Brain Infections
  • Syncope (Fainting)
  • Stroke
  • Sleep Disorders
  • Encephalitis

EEG test also carried out to know the level of brain activity when patient is in coma or to monitor brain activity during brain surgery.

EEG software- BrainAccess hardware

The BrainAccess hardware is offered with free EEG Software in the form of EEG SDK. The EEG software act as the communication medium between patient brain and external devices. This open source or free software controls, visualize and preprocess the EEG data.

This EEG software works with the help of C/C++ or Python API. The applications runs on Windows 10 or newer and Ubuntu 18.04. Users can integrate the brain access software in their projects, applications or products. The basic components of BrainAccess software installer are:

  • Brain access core:

The brain core access library consist an interface including BrainAccess electroencephalographs. It is used to control external device, configuration of brain acquisition parameters and EEG data streaming on the computer system.

The library functions are used to access raw EEG data and alter the settings of necessary channels. It also measure impedance and steam EEG data with additional input parameters if available. Users can monitor the battery and voltage state of device with brain access core library.

  • Brain access Preprocessor:

Brain access Preprocessor includes standard EEG signal processing tools. In general EEG preprocessing includes importing and down sampling Raw EEG data, Filter and references data, inspects electrodes and remove noisy channels from the EEG data, detrending EEG data, perform component analysis and save preprocess EEG data.

  • Brain access BCI Connect:

Brain access BCI algorithm component is the part of BCI Connect library. BCI algorithms can control and monitor thoughts (conscious and unconscious) and emotions of brain. This algorithms can discover complex brain waves up to 30 different expressions with the help of artificial intelligence. It consist different algorithms including SSVEP (steady-state-evoked-potential) detector algorithm and P300 Classifier.

  • C, C++ and Python API:

Users can connect brain access core and BCI libraries and functions via C, C++ and Python API. Python API includes Brain Access viewer.

  • Brain access viewer:

Brain access viewer is the application with the graphical user interface. Users can view the BrainAccess Core functionality on this interface. Users can save data, measure impedance, analyze EEG data on this viewer.

Users can download the BrainAccess hardware package for installation from the Download center. anyone can read about eeg sdk here. To access the download center, user need to purchase one of our brain access product. Users can connect us in case or any further questions.
