The electroencephalogram (EEG) is a mainstay of clinical neurology and is tightly correlated with brain function, but the specific currents generating human EEG elements remain poorly specified because of a lack of microphysiological recordings. The largest event in healthy human EEGs is the K-complex (KC), which occurs in slow-wave sleep. Here, we show(More)
BACKGROUND MRI changes due to status epilepticus (SE) often suggest a combination of cytotoxic and vasogenic edema, but it is unclear why only certain patients have MRI changes. OBJECTIVES To determine the frequency of MRI changes due to SE and the associated patient characteristics. METHODS We reviewed records for demographics, medical history, and MRI(More)
To evaluate cortical architecture in mesial temporal lobe epilepsy (MTLE) with respect to electrophysiology, we analyze both magnetic resonance imaging (MRI) and magnetoencephalography (MEG) in 19 patients with left MTLE. We divide the patients into two groups: 9 patients (Group A) have vertically oriented antero-medial equivalent current dipoles (ECDs). 10(More)
It is unclear why some patients with brain tumors present with seizures while others do not. As deformations of the brain due to the tumor growth are suspected to be in part responsible for seizures, we decided to compare the differences between the brain deformations in patients presenting with seizures versus those who did not. We modeled the brain(More)
Gilles de la Tourette's syndrome (TS) is a neurobehavioral disorder characterized by multiple motor and vocal tics, occurring longer than a year and causing marked distress along with social and occupational impairments in level of functioning. It can be accompanied by obsessive-compulsive behavior and attention deficit disorder. This report discusses the(More)
Sleep is known to be severely altered in temporal lobe epilepsy (TLE). Furthermore, sleep deprivation is one of the key factors contributing to cognitive deficits and drug resistance in TLE. In the past, "non-ictal" parasomnias, as well as parasomnia-like nocturnal episodes ultimately diagnosed as seizures, have been documented in epileptic patients.(More)
