[ 1 ] - Aspirin changes short term synaptic plasticity in CA1 area of the rat hippocampus

Introduction: The prostaglandin E2 (PGE2), a cyclooxygenase (COX) product, play critical roles in the synaptic plasticity. Therefore, long term use of COX inhibitors may impair the synaptic plasticity. Considering the wide clinical administration of aspirin and its unknown effects on information processing in the brain, the effect of aspirin and sodium salicylate on the short term synaptic p...

[ 2 ] - Electrophysiological characteristics of hippocampal CA1 neurons after spreading depression-triggered epileptic activity in brain slices

Introduction: A close link between spreading depression (SD) and several neurological diseases such as epilepsy could be demonstrated in many experimental studies. Epilepsy is among the most common brain disorders. Despite a large number of investigations, its mechanisms have not been yet well elucidated. Hippocampus is one of the important structures involved in seizures. The aim of this st...

[ 3 ] - Effect of chronic morphine administration on Ca2+/Calmodulin-Dependent protein kinase IIα activity in rat locus coeruleus and its possible role in morphine dependency

Introduction: The aim of this study was to assess the effect of Ca2+/calmodulin-dependent kinase IIα (CaMKIIα) inhibitor (KN-93) injection into the locus coeruleus (LC) on the modulation of withdrawal signs. We also sought to study the effect of chronic morphine administration on CaMKIIα activity in the rat LC. Methods: The research was based on behavioral and molecular studies. In the behav...

[ 4 ] - Spatial Learning and Memory in Barnes Maze Test and Synaptic Potentiation in ‎Schaffer Collateral-CA1 Synapses of Dorsal Hippocampus in Freely Moving Rats

Introduction: Synaptic plasticity has been suggested as the primary physiological mechanism underlying memory formation. Many experimental approaches have been used to investigate whether the mechanisms underlying long-term potentiation (LTP) are activated during learning. Nevertheless, little evidence states that hippocampal-dependent learning triggers synaptic plasticity. In this study, we in...

[ 5 ] - The Role of Adrenergic Receptors on Neural Excitability and Synaptic Plasticity: A Narrative Review

Adrenergic receptors have an important role in neural excitability and synaptic plasticity. Despite a lot of studies on these receptors, their exact role in brain disorders accompanied with hyperexcitability has not been determined. There are also controversies on their role in synaptic plasticity. In this review article, the important studies done in this regard have been reviewed to achieve a...
