Extrahippocampal Desynchronization in Nonlesional Temporal Lobe Epilepsy
Figure 3
Preictal and ictal desynchronization activity in patient no. 5. Upper panel: Number of channels with activity greater than 2.5 standard deviations of baseline activity. Second upper panel: Left AS, as defined in (2), that is, desynchronized activity in the left FOE during the preictal and ictal stages. Third upper panel: Right AS, as defined in (2), that is, desynchronized activity in the right FOE during the preictal and ictal stages. Lower panel: LIAS = Left As − Right AS, desynchronization imbalance, as defined in (3). In every panel, solid vertical line marks seizure onset.
