Persistence of Cortical Sensory Processing during Absence Seizures in Human and an Animal Model: Evidence from EEG and Intracellular Recordings
Absence seizures are caused by brief periods of abnormal synchronized oscillations in the thalamocortical loops, resulting in widespread spike-and-wave discharges (SWDs) in the electroencephalogram (EEG). SWDs are concomitant with a complete or partial impairment of consciousness, notably expressed by an interruption of ongoing behaviour together with a lack of conscious perception of external ...
متن کاملAbsence of Rapid Sensory Adaptation in Neocortex during Information Processing States
One prominent feature of sensory responses in neocortex is that they rapidly adapt to increases in frequency, a process called "sensory adaptation." Here we show that sensory adaptation mainly occurs during quiescent states such as anesthesia, slow-wave sleep, and awake immobility. In contrast, during behavior-ally activated states, sensory responses are already adapted. For instance, during le...
متن کاملAbsence seizures during sleep: who would have thunk it?
Commentary Two of the most fundamental aspects of caring for children with epilepsy is knowledge of seizure type and frequency of seizures. The recent report by Sadleir calls for a reassessment of each. What is an absence seizure? The 1981 International League Against Epilepsy (ILAE) classification system of seizures described the features of an " absence attack " to include its " sudden onset,...
متن کاملAbsence seizures in children.
INTRODUCTION About 10% of seizures in children with epilepsy are typical absence seizures. Absence seizures have a significant impact on quality of life. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for typical absence seizures in children? We searched: Medline, Embase, The Cochrane Library, and o...
متن کاملAbsence seizures during pregnancy in WAG/Rij rats.
Spontaneously occurring spike-wave discharges (SWDs) and serum concentrations of ovarian steroid hormones were investigated before, during and after pregnancy in WAG/Rij rats, a rat strain with genetically determined absence seizures. Eight groups of rats were included in the assays of progesterone and estradiol: rats at diestrus, at various days of pregnancy and at lactating days. The number o...
