Anterior cingulate cortex neuron subtypes differentially regulate seizures

Epilepsia, EarlyView.
Abstract Objective This study aimed to investigate the regulatory roles of distinct neuronal subtypes within the anterior cingulate cortex (ACC) in acute seizures and to identify cell type‐specific mechanisms underlying seizure modulation in this region. Methods Acute seizure models were established in mice via pentylenetetrazol injection.

Hippocampal network activity changes during early epileptogenesis predict subsequent epilepsy

Epilepsia, EarlyView.
Abstract Objective Despite decades of research, the circuit mechanisms that underlie focal epileptogenesis remain incompletely understood. In this study, we aimed to characterize the changes in hippocampal network activity induced by an epileptogenic insult.

Scn1a‐mediated developmental regulation of prefrontal cortex plasticity and cognition

Epilepsia, EarlyView.
Abstract Objective The voltage‐gated sodium channel Nav1.1, encoded by Scn1a, is essential for γ‐aminobutyric acid (GABA)ergic function, and its alteration is associated with neurological disorders such as Dravet syndrome and Alzheimer's disease. We previously demonstrated that local Nav1.1 dysfunction in the medial prefrontal cortex (mPFC) during ...

Theta oscillations, epileptogenesis, and focal seizures in rodent models of mesial temporal lobe epilepsy

Epilepsia, EarlyView.
Abstract Theta oscillations (4–12 Hz) are a prominent network rhythm within hippocampal and parahippocampal structures. Driven by cholinergic and γ‐aminobutyric acidergic inputs originating from the medial septum, physiological theta gates network excitability to control spatial navigation, memory encoding, and sensorimotor integration during specific ...

Kv3.1 activation suppresses provoked and spontaneous seizures in a mouse Dravet syndrome model

Epilepsia, EarlyView.
Abstract Objective γ‐Aminobutyric acidergic (GABAergic) parvalbumin‐positive (PV+) interneurons are critical for maintaining cortical inhibitory tone, with their dysfunction predictably leading to epilepsy. Rapid PV+ interneuron firing is essential for their normal function and is maintained in part by potassium voltage‐gated channels.

Exploration of High and Low Frequency Options for Subperception Spinal Cord Stimulation Using Neural Dosing Parameter Relationships: The HALO Study

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Subperception spinal cord stimulation (SCS) is described mostly utilizing waveforms that require high energy. However, the necessity of these waveforms for effective subperception has not been established. We aimed to explore whether effective subperception pain relief can be achieved using frequencies below 1 kHz.

Adeno‐associated virus‐mediated restoration of NaV1.1 in targeted brain regions ameliorates epilepsy in symptomatic Dravet syndrome mice

Epilepsia, EarlyView.
Abstract Objective Dravet syndrome (DS) is a developmental and epileptic encephalopathy primarily caused by haploinsufficiency of the SCN1A gene, which encodes the alpha subunit of NaV1.1 voltage‐gated sodium channel. The disease manifests with febrile and spontaneous seizures, developmental delay, cognitive impairment, and increased risk of sudden ...

Safety and Efficacy of 10 kHz Spinal Cord Stimulation for the Treatment of Refractory Chronic Migraine: A Prospective Long‐Term Open‐Label Study

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Background Refractory chronic migraine (rCM) is a highly disabling condition for which novel safe and effective treatments are needed. Safety and long‐term efficacy of paresthesia‐free high cervical 10 kHz spinal cord stimulation (SCS) were here prospectively evaluated for the treatment of rCM.

Loss of Ezh2 in the medial ganglionic eminence alters interneuron fate, cell morphology and gene expression profiles

Frontiers in Cellular Neuroscience
IntroductionEnhancer of zeste homolog 2 (Ezh2) is responsible for trimethylation of histone 3 at lysine 27 (H3K27me3), resulting in repression of gene expression.

Timing is everything: The effect of early‐life seizures on developing neuronal circuits subserving spatial memory

Epilepsia Open, EarlyView.
Abstract Spatial memory, the aspect of memory involving encoding and retrieval of information regarding one's environment and spatial orientation, is a complex biological function incorporating multiple neuronal networks. Hippocampus‐dependent spatial memory is not innate and emerges during development in both humans and rodents.
