Purpose: Focal cortical dysplasias (FCD) are localized regions of malformed cerebral cortex
and are very frequently associated with epilepsy in both children and adults. A broad …

We examined the significance and frequency of occurrence of rhythmic epileptiform
discharges (REDs) on the scalp EEGs of 74 patients with intractable partial epilepsy. We also …

Developmental and epileptic encephalopathy (DEE) is a group of conditions characterized
by the co-occurrence of epilepsy and intellectual disability (ID), typically with developmental …

Purpose: Absences are characterized by an abrupt onset and end of generalized 3–4 Hz
spike and wave discharges (GSWs), accompanied by unresponsiveness. Although previous …

Purpose: High‐frequency oscillations (HFOs) known as ripples (80–250 Hz) and fast ripples
(250–500 Hz) can be recorded from macroelectrodes inserted in patients with intractable …

Objective High‐frequency oscillations (HFOs) in the intracerebral electroencephalogram (EEG)
have been linked to the seizure onset zone (SOZ). We investigated whether HFOs can …

Grey matter heterotopias, demonstrated by MRI, may present with a broad spectrum of clinical
severity. We have studied 33 patients with periventricular nodular heterotopias (PNH); 19 (…

Because seizures originate from different pathological substrates, the question arises of
whether distinct or similar mechanisms underlie seizure generation across different pathologies. …

High frequency oscillations (HFOs) called ripples (80–250 Hz) and fast ripples (FR, 250–500
Hz) can be recorded from intracerebral EEG macroelectrodes in patients with intractable …

Purpose: In mesial temporal lobe epilepsy (MTLE) the epileptogenic area is confined to the
mesial temporal lobe, but other cortical and subcortical areas are also affected and cognitive …
