The “Mozart Effect” on Epileptiform Activity

Clinical Electroencephalography, 1998
The "Mozart Effect," using the Piano Sonata in D Major (K.448), was examined in patients with seizures. In 23 of 29 instances significant decreases in epileptiform activity were noted from patients even in coma, with status epilepticus or with periodic lateralized epileptiform discharges (PLEDs).

Nonconvulsive Epileptiform Activity Appearing as Ataxia

Archives of Pediatrics & Adolescent Medicine, 1982
Ataxia may be the result of otherwise silent epileptiform activity. We studied three patients, between 3 and 5 years of age, whose initial complaint was unsteadiness of gait. Each one of the patients had an epileptiform EEG with bursts of slow spike and wave activity.

Excitation and Inhibition Balance Underlying Epileptiform Activity

IEEE Transactions on Biomedical Engineering, 2020
The phenomenon of postictal generalized EEG suppression state (PGES) - a period with suppressed activity following seizure termination and has been found to be associated with sudden unexpected death in epilepsy - remains poorly understood. This article aims to examine the how the balance of excitation and inhibition (E/I balance) affect the dynamics ...

Epileptiform and non-epileptiform paroxysmal activity from isolated cortex after functional hemispherectomy

Electroencephalography and Clinical Neurophysiology, 1997
The relationship of acute complete cortical isolation to paroxysmal cerebral activity was examined in 16 patients with electrocorticography (ECOG) before and after functional hemispherectomy (FH). Burst-suppression activity appeared over isolated cortex in all cases, the severity of which could be increased by systemic administration of propofol or ...

Picrotoxin induced epileptiform activity in amygdaloid neurons

Neuroscience Letters, 1987
The effects of the epileptogenic agent, picrotoxin, on inhibitory postsynaptic potentials (IPSPs) were studied in the amygdala in vitro slice preparation. Picrotoxin was superfused onto the tissue and intracellular recordings were obtained from basolateral amygdaloid neurons (BLANs).

Reactive Occipital Epileptiform Activity: Is It Benign?

Epilepsia, 1991
SUMMARY: Occipital epileptiform activity that is almost continuous and reactive to eye opening has been associated with a childhood epilepsy syndrome and basilar migraine with seizures. An association of these syndromes with a benign course had been disputed.

Dendritic Mechanisms Underlying Penicillin-Induced Epileptiform Activity

Science, 1979
The action of penicillin on synaptically evoked dendritic activity was examined with the use of hippocampal slice preparations. Orthodormic activation of CA1 pyramidal neurons produced an excitatory-inhibitory postsynaptic potential sequence recorded intracellularly in the dendrites.

Giant Synaptic Potential Hypothesis for Epileptiform Activity

Science, 1981
According to one hypothesis, the paroxysmal depolarizing shift observed in the penicillin model of epilepsy results from a giant excitatory postsynaptic potential. This hypothesis has recently been questioned, primarily because it has never been subjected to rigorous experimental examination.

Epileptiform Activity

2009
EEG continues to be an important test to functionally evaluate people with suspected seizures. Although few specific EEG patterns exist for specific diseases, the presence of epileptiform discharges and patterns on the EEG may help identify certain syndromes. Clinicians using EEG in the evaluation and management of people with suspected epilepsy should

Epileptiform Activity in Electroencephalogram of Normal Children

Neuropediatrics, 2017
Objectives This prospective cohort study assessed the prevalence of epileptiform discharges (EDs) in a cohort of healthy Egyptian children aged 1 to 18 years. Methods Children with a history of unprovoked seizure disorders, family history of epilepsy, neurological or psychological disorder, or any other chronic illness were ...
