Fig. 1. Video-EEG monitoring in a mouse model of epilepsy: (A) A seizure detected by EEG, recorded from two epidural-screw electrodes, over left (LH) and right (RH) parietal areas, referred to a posterior electrode (cerebellar screw). (B) Background interictal activity characterized by ...
Automated seizure detection from within an electroencephalogram (EEG) by instrumental means employs novel algorithms within software, using specific measurements of individual waves
If the EEGs contained seizures or seizure-like activity, non-experts listening to sonified EEGs rated them as seizures with high specificity (students: 85 ± 9%; nurses: 82 ± 12%) compared to experts or non-experts viewing the EEGs visually (attendings: 95 ± 1%; fellows...
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. ...

These methods are usually patient dependent in the sense that one needs to know the morphology of the patient’s seizure in addition to the channels that capture the seizure activity. However, it has been shown that algorithms that take into account different seizure morphologies, including ...
