EEG/ERP System
Equipment Introduction
The Brain Products actiCHamp Plus system is a powerful tool for simultaneous EEG recording of up to 128 channels, with real-time electrode impedance measurement for optimal data quality. It features easy-to-prepare active electrodes and is highly integrated for multimodal recordings, including eye trackers, fNIRS, TMS, and more. This system is widely used in cognitive neuroscience research, brain-computer interface research, neural signal decoding, and clinical diagnosis of neurological disorders. Its applications span across various areas such as perception, attention, emotion, memory.
