Bath application of kainate (100-300 nM) induced a persistent gamma-frequency (30-80 Hz) oscillation that could be recorded in stratum radiatum of the CA3 region in vitro. We have previously described that in knockout mice lacking the gap junction protein connexin 36 (Cx36KO), gamma-frequency oscillations are reduced but still present. We now demonstrate that in the Cx36KO mice, but not in wild...

Subclinical rhythmic electrographic discharges of adults (SREDA) is an uncommon distinctive EEG rhythmic pattern with uncertain significance. We report a patient with transient global amnesia in whom an EEG recording, performed after the acute phase of the neurological event, showed SREDA. Based on this EEG finding, we discuss about a possible correlation between SREDA and transient global amne...

Electro-myographic observations were made on abdominal muscles of pregnant individuals under normal and some abnormal conditions at the Ekisaikai Hospital, Kobe. As has been announced by Kawakami (1), these observations preceded his experimental work on the effect of sexual hormones on the muscular activity of the human abdominal muscles. The muscles used were M. obliquus externus et internus. ...

Faults and damage in oil-filled power transformers has a devastating effect on the overall reliability of electrical power systems. Several factors, especially electrical and thermal stresses age the transformer and subject them to incipient faults. These faults, if left undetected will cause deterioration and eventually lead to failure of the transformer [1]. The presence of faults such as arc...

[1] We estimated electrical parameters of 48 located compact intracloud discharges (CIDs) using their measured electric fields and vertical Hertzian dipole approximation. This approximation is consistent with the more general bouncing‐wave CID model for a reasonably large subset of allowed combinations of propagation speed and channel length. For nine events, we estimated channel lengths from o...

• Determination of the defibrillation threshold of the heart is important not only for developing the technique of defibrillation per se but also for improving the design of instruments used for that purpose. Previous workhas shown the necessity of selecting, for the discharge circuit, parameters that will keep voltage as low as possible, but many questions concerning the optimal parameters for...

Observation of upward electrical discharges from thunderstorms has been sporadically reported in the scientific literature. According to their terminal altitudes, they are classified as starters (20-30 km), jets (40-50 km) and gigantic jets (70-90 km). They not only have a significant impact on the occupied atmospheric volumes but also electrically couple different atmospheric regions. However,...

We describe the case of a 15-year-old boy who had the diagnosis of benign partial epilepsy of childhood with centro-temporal spike. During the EEG a subclinical electrographic seizure was recorded. The discharges were clearly electropositive in T4 with positive phase reversal between derivations F8-T4 and T4-T6. The whole episode lasted less than one minute (45 sec). The interictal right medio-...

Approximately 30% of epilepsy patients suffer from drug-resistant epilepsy. Direct electrical stimulation of the epileptogenic zone is a potential new treatment modality for this devastating disease. In this study, we investigated the effect of two electrical stimulation paradigms, sustained low-frequency stimulation and short trains of high-frequency stimulation, on epileptiform discharges in ...
