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.

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.

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.

The dynamic functional connectivity peak index: Detection of interictal epileptic activity with fMRI

Epilepsia, EarlyView.
Abstract Objective Epileptogenic zone (EZ) localization is crucial for surgical treatment of patients with medication‐resistant epilepsy. Although simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) can detect interictal discharges for EZ localization, clinical adoption is limited by the need for specialized ...

Detection of focal impaired awareness seizures using a biometric shirt

Epilepsia Open, EarlyView.
Abstract Objective In recent years, seizure detection using wearable technology has gained significant attention in research. Most studies, however, have focused on detecting generalized or focal to bilateral tonic–clonic seizures. This study evaluates the feasibility of using a biometric shirt to detect focal impaired awareness seizures (FIAS) by ...

Programmable luminescent platform based on carbon quantum dots enables wavelength‐multiplexed optical data storage and encryption

FlexMat, EarlyView.
A carbon‐quantum‐dots (CQDs)‐based programmable luminescent platform is proposed for multidimensional optical information encryption and high‐capacity data storage by leveraging wavelength‐division multiplexing. Furthermore, a prototype tri‐layer optical disk is demonstrated, where data written via laser ablation on different CQD layers are retrieved ...

Dopaminergic novelty detection and theta oscillations: Virtual reality‐based adaptive interventions for cognitive enhancement in aging

Ibrain, EarlyView.
Aging‐related cognitive decline is associated with reduced dopaminergic signaling and disrupted theta oscillations, which together impair novelty detection and memory formation. This review shows how VR environments can be used to deliver adaptive, novelty‐rich stimuli that engage dopaminergic circuits and entrain theta rhythms, thereby enhancing ...

Complement C3 mediates adolescent social isolation‐induced hippocampal synaptic deficits and sex‐specific emotional dysfunction

Interdisciplinary Medicine, EarlyView.
Adolescent social isolation disrupts hippocampal function and exacerbates emotional symptoms, with sex‐specific patterns, as shown by human studies. In mice, social isolation decreased hippocampal synaptic density and calcium signaling, upregulated complement proteins, and activated complement‐mediated microglial synaptic phagocytosis.

Nonlinear Relations Between Resting Heart Rate Measures and Health Risk Behavior in Emerging Adulthood

Journal of Adolescence, EarlyView.
ABSTRACT Introduction Resting heart rate (HR) measures reflect autonomic processes that could predict health risk behavior (HRB) in emerging adulthood when risky behavior is prominent. However, prior studies and extant theories are inconsistent, such that the relationships between HR measures and HRB could be positive or negative in direction.
