What researchers measure

Primary outcomes

  1. Electroencephalography (EEG) signals in the ambulance

    Electroencephalography (EEG) is used for measurement. Electroencephalography (EEG) is a non-invasive technique used to record the electrical activity of the brain through electrodes placed on the scalp. These electrodes detect and amplify signals generated by the synchronous activity of neurons, particularly in the cerebral cortex. EEG provides a real-time measure of brain activity with high temporal resolution, typically capturing signals in the range of 1-100 Hz.

    Time frame: 10 minutes by boarding an ambulance in driving

Secondary outcomes

  1. Functional Near-Infrared Spectroscopy(fNIRS) signals in the ambulance

    Functional Near-Infrared Spectroscopy (fNIRS) is a non-invasive optical imaging technique used to measure changes in brain activity by detecting hemodynamic responses associated with neural activity. It relies on the absorption properties of near-infrared light, which penetrates the scalp and skull to assess oxygenated (HbO) and deoxygenated (HbR) hemoglobin levels in cortical regions.

    Time frame: 10 minutes by boarding an ambulance in driving
