Sevoflurane: EEG seizure activity in a child: case report
You have this test in a hospital over a few days. The medical staff take a video of you while the test records your brain activity. The video shows your doctor what happens to your body during a seizure or other brain event. Doctors sometimes call this test EEG monitoring or EEG telemetr...
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. ...
When an EEG is requested, it is important that the referring physician state the clinical question that is to be answered by the EEG. Common reasons for obtaining an EEG include a history of a clinical seizure and the need to rule out epileptiform activity; acute encephalopathy or coma of un...
Automated seizure detection from within an electroencephalogram (EEG) by instrumental means employs novel algorithms within software, using specific measurements of individual waves
The regions of neuropathology overlapped with areas of intense seizure activity. These data show that systemic kainic acid preferentially activates seizures in ... EW Lothman,RC Collins - 《Brain Research》 被引量: 1423发表: 1981年 Inhibition of the p44/42 MAP kinase pathway protects hippocampal ...
shows no clear lesion, a large complex lesion, or multiple potential epileptogenic lesions33,34. Such cases stand to benefit from non-invasive dynamical approaches to better characterise the brain networks involved in seizure dynamics. Here, we aim to apply a dynamical network approach to source ...
Hence, monitoring the brain electrical activity using EEG and analyzing its spectral information in the frequency domain can reveal seizure occurrences. However, EEG signals are often corrupted by noise, artifacts and/or brain activities (see Fig. 1a) that can be confused with seizure activities, ...
2. Mechanism of EEG Current flow to and from active synaptic knobs on the dendrites produces wave activity, while AP are transmitted along the axon. EEG signals generated by cortex Currents in extracellular space generated by summation of EPSPs and IPSPs 3. EEG Records During Epileptic Seizure ...
