Feedback control of excitability and high K+ induced epileptiform bursts in male rat hippocampal slices with a photocaged adenosine A1 receptor agonist

British Journal of Pharmacology, EarlyView.
Background and Purpose Adenosine is a potent regulator of neurotransmission and neuronal excitability, through activation of Gi coupled adenosine A1 receptors (A1Rs). Adenosine has gained interest as an anticonvulsant because of its endogenous involvement in ending seizure activity, but peripheral side effects require local application.

Dissociating role of Bassoon in glutamatergic and dopaminergic neurons in alcohol‐related behaviour and affective state in mice

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Alcohol abuse and affective disorders are severe comorbid psychiatric diseases characterized by impaired brain synaptic transmission. The role of presynaptic scaffolding proteins coordinating presynaptic plasticity and neurotransmitter release, such as Bassoon (Bsn), in the pathogenesis of these disorders remains elusive.

Synaptic ultrastructural alterations in human focal cortical dysplasia: Insights from volume electron microscopy

Epilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) is a developmental malformation of the cerebral cortex and a leading cause of drug‐resistant epilepsy in children and young adults. Disruption of the excitation–inhibition (E–I) balance is a hallmark of neuronal hyperexcitability in FCD, yet the underlying synaptic ultrastructural changes remain poorly ...

Spreading depolarization and its influence on epileptiform activity

Epilepsia, EarlyView.
Abstract Spreading depolarization (SD) is a transient disruption of electrographic activity that slowly propagates through the gray matter by chemical contiguity, and it is characterized by a large depolarization of neurons and glial cells. SD, which is associated with massive changes in ion homeostasis, including extreme increases in [K+]o, was shown ...

Neuronal hyperexcitability: A key to unraveling hippocampal synaptic dysfunction in Lafora disease

Epilepsia, EarlyView.
Abstract Background and Objective Lafora disease (LD) is a rare progressive disorder caused by mutations in the EPM2A or EPM2B genes, characterized by the accumulation of Lafora bodies, drug‐resistant epilepsy, and cognitive decline. To investigate the early molecular mechanisms of LD, we studied electrophysiological changes in the dentate gyrus (DG ...
