 ====== Bilateral synchrony ======
-  * mechanisms by which seizures that become secondarily generalised are not yet known fully
+{{page>template:update}}
+The term "bilateral synchrony" was introduced by [[Wilder Penfield]]. According to Penfield and Jasper “An epileptogenic lesion of the mesial or inferior aspect of a frontal lobe, although it is one-sided, may produce
+bifrontal synchronous discharges”. The mechanisms by which seizures that become secondarily generalised are not yet known fully.
+The wave and spike of petit mal is a primary bilateral synchronous discharge . . . ; it appears not to be related to a unilateral cortical focus, but may be of subcortical origin …. On the other hand, a bilateral synchronous discharge which can be shown to arise from a unilateral cortical focus we shall call secondary bilateral synchrony - //Tükel and Jasper//[(:cite:12998596>{{pmid>12998596}})]
   * it is important to differentiate between primary and secondary bilateral synchrony when bilaterally synchronous spike and wave discharges are seen on EEG
-  * Estimation of interhemispheric small time differences (TDs) during spike-wave bursts in the EEG by coherence and phase analysis is useful for differentiation between primary bilateral synchrony (PBS) and secondary bilateral synchrony (SBS) in epilepsy[(:cite:1378385>{{pubmed>1378385}})].
