#TheScience "The Science Behind mindBEAGLE"

As long as patients have enough cognitive functions to understand spoken messages, mindBEAGLE may be used as a communication tool. The system uses three different approaches to assess consciousness or to communicate:

 

Auditory Stimulation

Auditory Stimulation

Verbal instructions and tones are presented via in-ear phones. For assessment, numerous frequent stimuli are randomly mixed with some rare target stimuli (e.g. tones with a different pitch).

 

Tactile Stimulation

Tactile Stimulation

Vibrotactile stimulators can be attached to different areas of the patient’s body, such as the hands and stomach. If the patient is able to understand and follow the training instructions by counting the required stimuli, this approach can be used for communication.

 

Motor Imagery

Motor Imagery

In addition, imagined movements (e.g. of the left or right hand) can also be used to identify mental activity in DOC patients. If the patient is able to understand and follow the training instructions by performing the required motor imagery, it can be used for communication.

mindBEAGLE System Components

The mindBEAGLE Software

The mindBEAGLE software measures the brain's responses to certain stimuli and looks for significant differences in EEG patterns at specific times. The results are summarized in a report.

Image

EEG Cap

The g.GAMMAsys EEG cap is used to record brain activity with 16 electrodes, which are automatically analysed and classified by the mindBEAGLE software.

Image

Vibrotactile Stimulators

Vibrotactile Stimuli are used for assessment via Evoked potentials (EPs) that allow the patient to say "YES" or "NO" by focusing on the left or right hand.

In-Ear Phones

In-ear phones are used to deliver verbal instructions (e.g. to imagine left or right hand movement) for communication and to present auditory stimuli (higher or lower tones) for the assessment.
