Nonepileptic cortical cerebral blood flow and temporal lobe epileptogenicity M.E Weinand, I Takacs, D.M Labiner, G.L Ahern Pathophysiology Volume 6, Issue 2, Pages 135-141 (July 1999) DOI: 10.1016/S0928-4680(99)00014-0

Fig. 1 The relationship between peri-ictal nonepileptic cerebral blood flow (CBF) and seizure frequency. As nonepileptic CBF increases, seizure frequency increases. Left, 2-h peri-ictal period; center, 5-min pre-ictal period; right: 5-min post-ictal period. CBF in ml/100 g-min, seizure frequency in seizures/h.

Fig. 2 The relationship between peri-ictal epileptic and contralateral nonepileptic cerebral blood flow (CBF). Consistent with previously reported data which did not include complete analysis of the peri-ictal period [2], epileptic CBF is a negative linear function of nonepileptic CBF during the 5-min pre-ictal (left) and post-ictal (right) periods. CBF in ml/100 g-min. (Reproduced, in part, with modification by permission of Weinand et al. [2]). Pathophysiology 1999 6, 135-141DOI: (10.1016/S0928-4680(99)00014-0)

Fig. 3 The relationship between epileptic cerebral blood flow (CBF) and seizure frequency. As previously shown with the 2-h peri-ictal period [2]; during the 10-min peri-ictal period, as epileptic CBF decreases, seizure frequency increases. Left, 5-min pre-ictal period; right, 5-min post-ictal period. CBF in ml/100 g-min, seizure frequency in seizures/h. (Reproduced, in part, with modification by permission of Weinand et al. [2]).

Fig. 4 The association of the difference between nonepileptic and epileptic CBF and seizure frequency. The difference between nonepileptic and epileptic CBF is a positive linear function of seizure frequency during the 5-min pre-ictal (left) and post-ictal (right) periods.
