Instrumentation for EEG-based monitoring of the executive functions in a dual-task framework

Instrumentation for electroencephalographic (EEG)-based monitoring of the executive functions in a dual-task framework is proposed. The proposed system integrates in a single solution (i) the administration of the cognitive task, (ii) the EEG signal acquisition and processing, (iii) the data storage synchronized whit an external Gait Analysis system. The system is based on a wearable passive brain computer interface solution that allows EEG monitoring during gait, by means of acoustic stimuli. The centralized platform guarantees the synchronization of all the processes, and therefore, improves the state of the art accuracy in measurements related to executive functions and gait. An experimental validation demonstrated the feasibility of the proposed solution in terms of execution of cognitive tasks during gait, real-time monitoring of EEG signals, and synchronized storage of EEG data, gait and cognitive task performances.
