Bilateral ictal eye closure in focal epileptic seizures: SEEG retrospective observational assessment from a tertiary epilepsy center

Epileptic Disorders, EarlyView.
Abstract Ictal eye closure is commonly associated with functional seizures but may also occur in epileptic seizures. We retrospectively reviewed 113 consecutive stereo‐EEG (SEEG) recordings from adults with drug‐resistant focal epilepsy (2015–2024) to identify prolonged bilateral eye closure during seizures.

Exposing piaget's scheme: Empirical evidence for the ontogenesis of coordination in learning a mathematical concept [PDF]

, 2016
The combination of two methodological resources-natural-user interfaces (NUI) and multimodal learning analytics (MMLA)-is creating opportunities for educational researchers to empirically evaluate seminal models for the hypothetical emergence of concepts

Glymphatic dysfunction couples with cortical excitation–inhibition imbalance in epilepsy: Evidence from Rasmussen encephalitis

Epilepsia, EarlyView.
Cong Fu et al. demonstrate that glymphatic system dysfunction is linked to enhanced inhibitory cortical activity using diffusion MRI and EEG. These findings highlight a mechanistic link between perivascular fluid dynamics and neuronal activity, suggesting a role for glymphatic function in maintaining cortical stability in epilepsy.

Pediatric sensorimotor cortical responsiveness to intracerebral stimulation during stereoelectroencephalographic monitoring: Age effects and area specificity

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to determine how age influences clinical responsiveness to intracerebral electrical stimulation (IES) in children across primary and secondary sensorimotor cortices and to assess age effects on response complexity and area‐specific responsiveness.

Stereo‐EEG mapping of visual working memory with task‐related high‐gamma modulations

Epilepsia, EarlyView.
Abstract Objective We describe a safe, informative, and easy‐to‐implement approach for presurgical mapping of visual working memory (VWM) with stereo‐electroencephalography (SEEG). Methods Twenty‐four patients with drug‐resistant epilepsy, 11–23 years of age, performed a single‐probe change detection VWM task, during SEEG monitoring.

ECoG activity distribution patterns detects global cortical responses following weak tactile inputs

iScience
Summary: Many studies have suggested that the neocortex operates as a global network of functionally interconnected neurons, indicating that any sensory input could shift activity distributions across the whole brain.

Integrating multivariate resting‐state fMRI features to localize epileptic networks in common childhood epilepsy

Epilepsia, EarlyView.
Abstract Objective Accurate localization of epileptic activity remains challenging when interictal discharges are absent or sparse. Although resting‐state functional MRI (rs‐fMRI) is noninvasive, individual rs‐fMRI metrics provide inconsistent and incomplete localization.

CaMKIIβ insufficiency disrupts cortical networks, producing aberrant low‐gamma oscillations and seizure susceptibility

Epilepsia, EarlyView.
Abstract Objective Pathogenic variants in the calcium/calmodulin‐dependent protein kinase II B gene (CAMK2B) have been associated with neurodevelopmental disorders, including epilepsy, yet the mechanisms underlying cortical dysfunction remain largely unclear.

Tracking the evolution of a single choice

eLife
Measuring the activity of hundreds of neurons in macaque brains simultaneously provides further evidence that drift-diffusion dynamics underlie how decisions are made in the brain.
