Involvement of hippocampal AMPA glutamate receptor changes and the cAMP/protein kinase A/CREB-P signalling pathway in memory consolidation of an avoidance task in rats

open access: yesBrazilian Journal of Medical and Biological Research, 1997
Training in step-down inhibitory avoidance (0.3-mA footshock) is followed by biochemical changes in rat hippocampus that strongly suggest an involvement of quantitative changes in glutamate AMPA receptors, followed by changes in the dopamine D1 receptor ...

Absence seizures: Update on signaling mechanisms and networks

open access: yesEpilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

The spectrum of Ischemia-induced white matter injury varies with age [PDF]

open access: yes, 2013
Stroke is a neurological condition that targets the whole range of the human population, from the pre-term infant to the elderly and is a major cause of death worldwide (Ingall 2004).

Status epilepticus: Updates on mechanisms and treatments

open access: yesEpilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

GluA2-lacking AMPA receptors in hippocampal CA1 cell synapses: evidence from gene-targeted mice

open access: yesFrontiers in Molecular Neuroscience, 2012
The GluA2 subunit in heteromeric AMPA receptor channels restricts Ca2+ permeability and block by polyamines, rendering linear the current-voltage relationship of these glutamate-gated cation channels.

P2X7 receptors exert a permissive effect on the activation of presynaptic AMPA receptors in rat trigeminal caudal nucleus glutamatergic nerve terminals

open access: yesThe Journal of Headache and Pain, 2020
Background Purine receptors play roles in peripheral and central sensitization and are associated with migraine headache. We investigated the possibility that ATP plays a permissive role in the activation of AMPA receptors thus inducing Glu release from ...

The multiple hit model of infantile and epileptic spasms: The 2025 update

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Infantile and epileptic spasms syndrome (IESS) is a developmental and epileptic encephalopathy manifesting with epileptic spasms and poor neurodevelopmental outcomes. There is an urgent need for the development of more effective and tolerated therapies.

Stargazin and AMPA receptor membrane expression is increased in the somatosensory cortex of Genetic Absence Epilepsy Rats from Strasbourg

open access: yesNeurobiology of Disease, 2011
Absence-like seizures in the Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model are believed to arise in hyperexcitable somatosensory cortical neurons, however the cellular basis of this increased excitability remains unknown. We have previously

Neonatal seizures and GABAergic drugs: Scylla and Charybdis?

open access: yesEpilepsia Open, EarlyView.
Abstract Neonates have a high incidence of seizures that are frequently difficult to control with conventional first‐line anti‐seizure medications, which are gamma‐aminobutyric acid (GABA) agonists. The reasons for this clinical problem are multifold but are likely related to the unique physiology of the immature nervous system. Specifically, the early
