A representative hippocampal seizure from human subject MH1 (RC + S). (Top) Time-frequency characteristics (z-scored spectrogram), (Bottom) raw intracranial EEG data with the physician annotated seizure (onset denoted by arrow) and model seizure probability (bold trace) for patient MH1 in the out-of-sample data set is shown. The figure demonstrates how the probability of the long-short-term memory (LSTM) network changes over a peri-seizure period (pre-ictal, ictal and post-ictal period). The high probability (near 1) in the peri-seizure region highlights the impact of the LSTM function for raising the probability during and around the seizure time.
