1 Electrocorticographic factors associated with temporal lobe epileptogenicity 
M.E Weinand, M Deogaonkar, M Kester, G.L Ahern, D.M Labiner  Pathophysiology  Volume 7, Issue 1, Pages (April 2000) DOI: /S (99)

2 Fig. 1 Subdural electrocorticographic (ECoG) record of medial temporal lobe ictal onset (arrow). Compared to lateral or regional (medial and lateral) temporal lobe seizure onset, medial temporal lobe ECoG ictal onset is associated with greatest seizure frequency. LMT, left medial temporal; RMT, right medial temporal lobe subdural electrodes, respectively, (1, most distal electrode; 4, most proximal electrode). Pathophysiology 2000 7, 33-39DOI: ( /S (99) )

3 Fig. 2 Subdural electrocorticographic (ECoG) record of frontal lobe desynchronization (ROF 1–8) in association with temporal (RMT 1–4) lobe ictal ECoG onset. Presence of ictal frontal lobe desynchronization is associated with low seizure frequency. ROF, right orbital-frontal; RMF, right medial frontal; RMT, right medial temporal subdural strips. (1, most distal electrode; 4, most proximal electrode). Pathophysiology 2000 7, 33-39DOI: ( /S (99) )

4 Fig. 3 Subdural electrocorticographic (ECoG) record of interhemispheric propgation time (IHPT). The best statistical model finds that seizure frequency decreases logarithmically as IHPT increases. In this illustration, IHPT=12.5 s. LMT, left medial temporal; RMT, right medial temporal lobe subdural electrodes. (1, most distal electrode; 4, most proximal electrode).
