β‐Hydroxybutyrate reduces neuronal excitability via GIRK channels

open access: yesEpilepsia, EarlyView.
β‐Hydroxybutyrate decreases neuronal excitability by activating GIRK channels through HCAR2 signaling, providing a cellular mechanism that may contribute to the antiseizure effects of the ketogenic diet. Abstract Objective The ketogenic diet is used to treat drug‐resistant epilepsy, yet the molecular mechanisms coupling metabolic state to seizure ...

Temperature homeostasis disruption and hypothalamic alterations in experimental drug‐resistant epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Elevated body temperature may increase seizure risk, yet the relationship between thermoregulation and seizures, as well as the underlying mechanisms, remains poorly understood. We investigated whether thermoregulatory control is altered in experimental temporal lobe epilepsy (TLE), as such impairment could reduce the ability of ...

Scn1a‐mediated developmental regulation of prefrontal cortex plasticity and cognition

open access: yesEpilepsia, 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

open access: yesEpilepsia, 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 ...

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

open access: yesEpilepsia 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.
