PORTABLE BRAIN ACTIVITY SENSING PLATFORM FOR ASSESSMENT OF VISUAL FIELD DEFICITS

摘要

Methods, systems and devices for monitoring electrical signals in the brain are disclosed. In one aspect, a system for monitoring electrical brain activity associated with a user''s field of view includes a sensor unit for acquiring EEG signals including a plurality of EEG sensors attached to a casing attachable to a user''s head, Visual display unit that can be attached to the user''s head over the user''s eyes to present a visual stimulus that causes multi-focus steady-state visual-evoked potentials (mfSSVEP) within the EEG signals represented by the user acquired by the sensor unit And a data processing unit communicating with the sensor unit and the visual display unit for analyzing the acquired EEG signals and calculating an evaluation of the user''s visual field, wherein the evaluation indicates whether there are visual defects in the user''s field of view do.
