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.

The role of dopamine D-like receptors in a "depotentiation-like effect" of deep brain stimulation in kindled rats.

The mechanisms involved in the anti-seizure effects of low-frequency stimulation (LFS) have not been completely determined. However, G-protein-coupled receptors, including D-like receptors, may have a role in mediating these effects. In the present study, the role of D-like receptors in LFS' anti-seizure action was investigated.

Antiepileptic and Antioxidant Effect of Brassica nigra on Pentylenetetrazol-Induced Kindling in Mice.

Considering the high rate of epilepsy today, with respect to the insufficiency of the available therapies, new strategies and methods are recommended for medical treatment of epileptic patients. Therefore, the present study experimentally investigated the anticonvulsant effect of a herbal medicine candidate brassica nigra, by using kindling method. Sixty male mice were randomly selected and divided into six experimental groups (n = 10) including: 1-control, 2-pentylentetrazole (PTZ)-kindled mice, 3-positive control group received valproate (100 mg/Kg) as anti-convulsant drug, 4-5 and 6 received brassica nigra seed extract in three doses (75, 150 and 300 mg/Kg; IP).
