In the context of focal drug-resistant epilepsies, the surgical resection of the epileptogenic zone (EZ), the cortical region responsible for the onset, early seizures organization, and propagation, may be the only therapeutic option for reducing or suppressing seizures. The rather high rate of failure in epilepsy surgery of extra-temporal epilepsies highlights that the precise identification o...

The relationship between electrophysiological and functional magnetic resonance imaging (fMRI) signals remains poorly understood. To date, studies have required invasive methods and have been limited to single functional regions and thus cannot account for possible variations across brain regions. Here we present a method that uses fMRI data and singe-trial electroencephalography (EEG) analyses...

The purpose of this communication is to review 17 cases of subacute sclerosing pan-encephalitis and to draw attention to a clinical feature which we believe to be pathognomonic. Greenfield (1950) united under this term those forms of subacute encephalitis previously described by Dawson (1933, 1934), Van Bogaert (1945), Pette and D6ring (1939), Brain, Greenfield, and Russell (1948), and Lhermitt...

seizure is the most common neurologic disorder in the pediatric age. obtaining thorough history and performing complete examination as well as electroencephalography (eeg) are very important in confirming the diagnosis and finding the cause. epileptiform activity may be enhanced by activating procedures including sleep deprivation. in this study we performed short duration (up to 8 hours) sleep...

Brain Computer Interface is a technique which allows people to interact with machines independent of muscles. Brain Computer Interface record the electrical signals from the brain and convert the recorded signals into corresponding control signals with the help of specialized computer. The main purpose of Brain Computer Interface is to enable the paralyzed people to communicate with their envir...

Brain tumor is inherently serious and life-threatening disease. Brain tumor builds the intracranial pressure in the brain, by shifting the brain or pushing against the skull, and also damaging nerves and healthy brain tissues. This intracranial pressure affects and interferes with normal brain functionality, which results in generation of abnormal electrical activities from brain. With recent d...

The discovery that electroencephalography (EEG) contains useful information at frequencies above the traditional 80Hz limit has had a profound impact on our understanding of brain function. In epilepsy, high-frequency oscillations (HFOs, >80Hz) have proven particularly important and useful. This literature review describes the morphology, clinical meaning, and pathophysiology of epileptic HFOs....

Commentary Treatment-resistant epilepsy remains a challenge for roughly one-third of patients with epilepsy (1). Although epilepsy surgery provides an excellent treatment option for some patients , the process of identifying proper candidates remains a labor-intensive process. For patients without clear MRI lesions or with discordant MRI and video-EEG data, additional testing is often required ...
