Patent Abstract:

The invention includes the design of a portable and wearable headband with three electrodes for subjective assessment of cortical and brainstem-evoked auditory response extraction. Three electrode slots are designed for two configurations: (i) Fpz, Fz, and Cz, and (ii) Fpz, Cz, and Pz, following the international 10-20 system for scalp electrode placement. In the case of auditory experiments, a wet electrode was placed at Fpz for auditory brainstem response (ABR) acquisition, and two dry electrodes were located at Fz and Cz for cortical auditory evoked potential (mismatch negativity – MMN) acquisition. Additionally, the device was manufactured using a precise proportion of rigid and flexible resin to ensure an intact skin-electrode interface with optimal ease of operation, comfortable head size adjustability, and robust signal fidelity. Moreover, a provision for swapping electrodes from the anterior (Fz and Cz) to the posterior (Cz and Pz) side of the head also broadens the scope involving visually evoked potential extraction.
