Seizure Detection and Network Dynamics of Generalized Convulsive Seizures: Towards Rational Designing of Closed-Loop Neuromodulation
Table 1
Classification of the seizures stages using data-driven approach on Granger’s Causality data; principle component analysis (PCA) showed that the three stages had distinct mean Granger’s Causality values.
