Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

Cytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Engineering and Characterization of a Fluorescent Fission Yeast Arp2/3 Complex for Single Molecule Mechanistic Investigations

Cytoskeleton, EarlyView.
ABSTRACT Arp2/3 complex is a seven‐component protein complex that facilitates the assembly of branched actin filament networks by binding to pre‐existing “mother” actin filaments and initiating the nucleation of new branched “daughter” filaments. Arp2/3 complex must be activated by a nucleation promoting factor such as the WASP/Scar protein family. The

Distinct thalamic functional connectivity and volume patterns across focal epilepsies in children: A multimodal neuroimaging study

Epilepsia, EarlyView.
Abstract Objective The thalamus is a key hub in seizure propagation, and its nuclei are emerging targets for neuromodulation. However, the contributions of individual nuclei to epileptic networks remain unclear, particularly in children, who are less studied than adults.

Inroads into epilepsy through high‐frequency oscillations: Achievements and benchmark areas for improvement

Epilepsia, EarlyView.
Abstract High‐frequency oscillations (HFOs) were discovered more than 20 years ago, and since then they have been studied intensively in the context of epilepsy. HFOs encompass a broad spectrum of oscillations, typically ranging from 80 Hz to several kHz, that include both normal and pathological oscillations, documented in people with epilepsy and ...

Open diffusion magnetic resonance imaging and connectivity data for epilepsy and surgery: The IDEAS II release

Epilepsia, EarlyView.
Abstract Objective Epileptic seizures are generated in cerebral networks that propagate ictal and interictal activity. The structure of cerebral networks underpinning epileptic activity can be inferred from diffusion‐weighted magnetic resonance imaging (DWI).

Contralateral language network integration predicts and protects against naming decline after temporal lobe resection

Epilepsia, EarlyView.
Abstract Objective Anterior temporal lobe resection (ATLR) is an effective treatment for drug‐resistant temporal lobe epilepsy (TLE) but carries a substantial risk of language impairment, particularly in naming. Understanding and predicting the impact of ATLR on language functions remains a major clinical challenge.

Sleep magnetoencephalography enhances detection and source imaging of seizures and fast oscillations in focal cortical dysplasia

Epilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) causes drug‐resistant epilepsy requiring presurgical evaluation. Invasive electroencephalographic (EEG) studies demonstrate that sleep modulates epileptic activity, including interictal epileptiform discharges (IEDs), fast oscillations (FOs) in the beta (14–40 Hz) and gamma (40–80 Hz) frequency bands ...

Thalamic connectivity mirrors spatial maps of network dysfunction in nonlesional focal epilepsy

Epilepsia, EarlyView.
Abstract Objective Focal epilepsy is increasingly conceptualized as a network disorder, yet the extent to which network dysfunction reflects a shared phenotype remains unknown. Spatially conserved patterns of network dysfunction may implicate a centralized mechanism underlying widespread impairment.

AI‐based localization of the epileptogenic zone using intracranial EEG

Epilepsia Open, EarlyView.
Abstract Artificial intelligence (AI) is rapidly transforming our lives. Machine learning (ML) enables computers to learn from data and make decisions without explicit instructions. Deep learning (DL), a subset of ML, uses multiple layers of neural networks to recognize complex patterns in large datasets through end‐to‐end learning.

Neuropsychological correlations with fornix and hippocampus in temporal lobe epilepsy demonstrated with diffusion tensor imaging

Epilepsia Open, EarlyView.
Abstract Objective Memory dysfunction is a common disabling comorbidity in temporal lobe epilepsy (TLE) and hippocampal sclerosis (HS). While bilateral fornix diffusion abnormalities have been reported in TLE using diffusion tensor imaging (DTI), the impact of fornix pathology on cognitive outcomes remains unclear.
