Inhibition of the p44/42 MAP kinase pathway protects hippocampal neurons in a cell-culture model of seizure activity. Excessive release of glutamate and the subsequent influx of calcium are associated with a number of neurological insults that result in neuronal death. The... Murray,Alessandrini,A...
While the LNA widened the population of HFO that could be detected, both CD and LNA recordings yielded a similar prediction of seizure activity with our HFO detection algorithm. HFO in scalp EEG are associated with HFO in ECoG The location of the highest HFO rates in scalp EEG corresponded ...
We designed patient-specific algorithms for seizure prediction to analyze the influence of envisioning the chronology of brain activity as a post-processing stage. For this, two distinct methodologies were adopted, along with a control one based on the most common framework. As presented in Fig. ...
(ILAE) classification. These researchers found only 22 children with ictal EEG showing a seizure onset purely originating from a unilateral temporal region. The authors concluded that video-EEG monitoring may fail to capture habitual episodes. To maximize the utility of studies in the future, a ...
The ability to cortisone to modify EEG and seizure activity was investigated in the baboon, Papio papio. Acute intramuscular doses (0.5–4 mg/kg) caused a dose-dependent increase in seizure response to a flashing light stimulus. This increase in seizure response was apparent in both seizure ...
We note that E v and I v are not the only parameters that can change the profile of the oscil- lations; reducing E 0 (the median background drive to the excitatory population) can also eradicate the seizure-like oscillations. Next we examine the bifurcation structure of the excitatory-...
For example, if you have a seizure disorder, the EEG can show where abnormal activity in your brain comes from and can help distinguish between generalized or focal seizures. An EEG is of value for diagnosing epilepsy only if it detects patterns typical of epilepsy. If it doesn’t detect ...
Subcortical neuronal activity is highly relevant for mediating communication in large-scale brain networks. While electroencephalographic (EEG) recordings provide appropriate temporal resolution and coverage to study whole brain dynamics, the feasibility to detect subcortical signals is a matter of debate. ...
