B-Alert X24 - Wireless EEG

B-Alert 24 Channel Wireless EEG

The B-Alert X24 is a powerful, comprehensive system for mobile neurophysiological data acquisition and analysis. Comfortable, lightweight headgear delivers real-time EEG for quantitative analyses, LORETA, BCI, neurofeedback training, single-trial ERPs, and the validated B-Alert Cognitive State Metrics. The system includes the External Syncing Unit – MultiChannel (ESU-MC) for millisecond time synchronization with other systems. From biomarker development to neurorehabilitation applications, the B-Alert X24 is the most robust medical-grade, wireless-EEG system available.
