Entropy analyses of spatiotemporal synchronizations in brain signals from patients with focal epilepsies
نویسنده
چکیده
The electroencephalographic (EEG) data intracerebrally recorded from 20epileptic humans with different brain origins of focal epilepsies or types of seizures, ages andsexes are investigated (nearly 700 million data). Multi channel univariate amplitude analysesare performed and it is shown that time dependent Shannon entropies can be used to predictfocal epileptic seizure onsets in different epileptogenic brain zones of different patients.Formations or time evolutions of the synchronizations in the brain signals from epileptogenicor non epileptogenic areas of the patients in ictal interval or inter-ictal interval are furtherinvestigated employing spatial or temporal differences of the entropies.

Generating the Visual Biofeedback Signals Applicable to Reduction of Wrist Spasticity: A Pilot Study on Stroke Patients
Introduction: Application of biofeedback techniques in rehabilitation has turned into an exciting research area during the recent decade. Providing an appropriate visual or auditory biofeedback signal is the most critical requirement of a biofeedback technique. In this regard, changes in Surface Electromyography (SEMG) signals during wrist movement can be used to generate an indictable visual b...
متن کاملDetection of schizophrenia patients using convolutional neural networks from brain effective connectivity maps of electroencephalogram signals
Background: Schizophrenia is a mental disorder that severely affects the perception and relations of individuals. Nowadays, this disease is diagnosed by psychiatrists based on psychiatric tests, which is highly dependent on their experience and knowledge. This study aimed to design a fully automated framework for the diagnosis of schizophrenia from electroencephalogram signals using advanced de...
متن کاملMEG source localization in extratemporal epilepsy
Although patients suffering from medically intractable epilepsies originating from other than the temporal lobe are less numerbale than those with temporal lobe epilepsies (TLE), localization of the epileptogenic region in extratemporal epilepsies (ETE) is considered as much more demanding than in TLE [1, 2]. Even if seizure semiology may hint at the origin in specific parts of the brain [3-7],...

Introduction and Aims: Alzheimer’s disease is the most prevalent neurodegenerative disorder and a type of dementia. 80% of dementia in older adults is because of Alzheimer’s disease. According to multiple research articles, Alzheimer's has several changes in EEG signals such as slowing of rhythms, reduction in complexity and reduction in functional associations, and disordered functional commun...
