sharp wavestemporalThe clinical correlates and EEG characteristics of rolandic positive sharp waves in neonatal EEG have been studied systematically. Morphologically similar positive sharp waves have been reported to occur in the temporal areas (PTS). Their significance is, however, unclear. We reviewed...
The timing of hypoxia-ischemia (HI) in preterm infants is often uncertain and there are few biomarkers to determine whether infants are in a treatable stage of injury. We evaluated whether epileptiform sharp waves recorded from the parietal cortex could provide early prediction of neuronal loss ...

The designation "controversial EEG wave forms" refers to a number of EEG patterns that tend to be more frequently detected in psychiatric populations and their association with epilepsy is weak, if at all. Included under this category are the Small Sharp Spikes (SSS), the Mitten pattern, the ...
Turtle EEG consists of a low voltage background interspersed by spontaneous large sharp waves (LSWs). Noradrenaline (NA, 5–40 μM) induced (or enhanced) the generation of LSWs in a dose-dependent manner. Pharmacological experiments suggest the participation of α and β receptors in this ...
For the purpose of topographical analysis concerning EEG in epilepsy, we developed a method of dynamic topography, in which interspike interval histogram and computerized topography of EEG were combined. Twenty-four-channels EEGs including sixteen channels out of the international 10–20 system and eig...
Excitatory currents in CA1 in str. oriens (blue sinks and black negative waves, black arrow) were accompanied by return currents in str. radiatum (red sources). Note ripples in all CA1 pyramidal layer sites. See also Figure S1. Brain State-Dependent SPW-Rs in CA1, CA2, and CA3 Areas...
