摘要：
Methods systems and devices are disclosed for monitoring electrical signals of the brain. In one aspect a system for monitoring electrical brain activity associated with visual field of a user includes a sensor unit to acquire electroencephalogram (EEG) signals including a plurality of EEG sensors attached to a casing attachable to the head of a user a visual display unit attachable to the head of the user over the user s eyes to present visual stimuli in which the visual stimuli is configured to evoke multifocal steady state visual evoked potentials (mfSSVEP) in the EEG signals exhibited by the user acquired by the sensor unit and a data processing unit in communication with the sensor unit and the visual display unit to analyze the acquired EEG signals and produce an assessment of the user s visual field in which the assessment indicates if there is a presence of visual field defects in the user s visual field.
