Detailed Documentation
This method computes the second-order moment energy of EEG signals from the C3 and C4 channels, primarily used for identifying imagined left and right hand movements. In brain-computer interface research, analyzing EEG signals enables accurate detection of motor imagery tasks. The calculation typically involves processing raw EEG data through bandpass filtering (e.g., 8-30 Hz for mu and beta rhythms), squaring the amplitude values, and averaging over time windows to extract energy features. This approach provides critical data and reference metrics for BCI systems. Furthermore, the methodology can be extended to other domains such as motor rehabilitation. Thus, research and application of this technique hold significant value for both clinical and experimental neuroscience.
