associated with ictal activity reflected the existence of a significantly higher baseline for oxygen metabolism in the epileptogenic cortices.  ...  To that end, we first analyzed intracranial recordings (electrophysiology, laser Doppler flowmetry and optical imaging) obtained from the seizure onset zones during ictal periods and then used these data  ...  A 32-channel EEG mini-cap specifically designed for rodents [33] was placed on top of the epileptic rat's scalp to record the EEG signals (PZ3, Tucker-Davis Technology).  ...
