OBJECTIVE Lennox-Gastaut syndrome, and the similar but less tightly defined Lennox-Gastaut phenotype, describe patients with severe epilepsy, generalized epileptic discharges, and variable intellectual disability. Our previous functional neuroimaging studies suggest that abnormal diffuse association network activity underlies the epileptic discharges of(More)
Individuals with focal epilepsy have heterogeneous sites of seizure origin. However, there may be brain regions that are common to most cases of intractable focal epilepsy. In this study, we aim to identify these using multivariate analysis of task-free functional MRI. Fourteen subjects with extratemporal focal epilepsy and 14 healthy controls were included(More)
OBJECTIVES Lennox-Gastaut syndrome (LGS) is a severe epilepsy of childhood onset associated with intellectual disability and multiple seizure types. Characteristic interictal electrographic discharges include generalized paroxysmal fast activity and slow spike and wave, which we have previously shown recruit widespread areas of association cortex. We wished(More)
OBJECTIVE To investigate whether genetics, underlying pathology or repeated seizures contribute to atrophy in specific white matter tracts. METHODS Medically-refractory unilateral temporal lobe epilepsy with hippocampal sclerosis (HS-TLE, n=26) was studied as an archetype of focal epilepsy, using fixel-based analysis of diffusion-weighted imaging. A(More)
X-ray free-electron lasers (XFELs) deliver x-ray pulses with a coherent flux that is approximately eight orders of magnitude greater than that available from a modern third-generation synchrotron source. The power density of an XFEL pulse may be so high that it can modify the electronic properties of a sample on a femtosecond time scale. Exploration of the(More)
OBJECTIVE Childhood absence epilepsy (CAE) is a childhood-onset generalized epilepsy. Recent fMRI studies have suggested that frontal cortex activity occurs before thalamic involvement in epileptic discharges suggesting that frontal cortex may play an important role in childhood absence seizures. Neurocognitive deficits can persist after resolution of the(More)
