Clinically validated battery of touch screen tasks effectively identified epilepsy patients with impaired memory and executive functions. Patients with memory and executive function deficits showed significantly decreased electroencephalography (EEG) theta power in the anterior prefrontal cortex. Theta power from all four frontal pole EEG electrodes correlated with the behavioral measures of memory and executive functions.

AbstractWhile high-frequency oscillations (HFOs) and their stereotyped clusters (sHFOs) have emerged as potential neuro-biomarkers for the rapid localization of the seizure onset zone (SOZ) in epilepsy, their clinical application is hindered by the challenge of automated elimination of pseudo-HFOs originating from artifacts in heavily corrupted intraoperative neural recordings.

1 Introduction Neural information processing is encoded by rhythmic oscillations. Noninvasive imaging of network dynamics of such neural rhythms is of significance for elucidating the mechanism of brain function and aiding clinical management of brain disorders. Epilepsy is a common neurological disorder affecting about 70 million patients worldwide,[1] one third of whom cannot be managed by medication alone.

AbstractEpilepsy, a neurological disorder affecting millions worldwide, poses great challenges in precisely delineating the epileptogenic zone, the brain region generating seizures, for effective treatment.

Neuromodulation and brain–computer interfaces are rapidly evolving fields with distinct origins but with the shared goal of improving the lives of people with neurological and psychiatric disorders or injuries. Their increasing technological overlap provides new opportunities for collaborative work and rapid progress in neurotechnology.
