Abstract —The mechanisms of the ketamine antidepressant effects observed in humans and laboratory animals are not fully understood. To further clarify role brain serotonergic (5-HT) activity action drugs, optogenetic inhibition 5-HT neurons rat dorsal raphe nucleus (DRN) was applied. In control animals, a subanesthetic dose alleviated their depressive-like behavior tail suspension test. Inhibit...

introduction: cholinergic systems are involved in learning and memory. scopolamine, a muscarinic acetylcholine receptor antagonist, is used as a standard/ reference drug for inducing cognitive deficits in healthy humans and animals. the purpose of this study was to evaluate the effects of scopolamine on avoidance memory and number of neurons in rat’s hippocampus. . methods: thirty five male alb...

background: oleuropein is a phenolic compound which is present in the olive leaf extract. the purpose of the present study was to investigate the neuroprotective effect of oleuropein as an antioxidant agent on the substantia nigra in aged rats. methods: twenty 18-month-old wistar rats (450-550 g) were randomly divided into control and experimental groups. the experimental group received a daily...

background and objective: parkinson's disease (pd) is characterized by a progressive loss of dopaminergic neurons in substantia nigra. in recent years, there have been interests in the role of the free radical damage in pd. cinnamon and its derivative, cinnamaldehyde acts as powerful antioxidant and anti-inflammatory agents. this research focused on the effects of cinnamon extract and cinn...

The identity of the neurotransmitter of subthalamic nucleus neurons has not been definitively established. GABA, glycine, and glutamate have all been hypothesized to be the neurotransmitter of these neurons. Immunohistochemistry with 3 well characterized antisera against glutamate, GABA, and glycine were used to study feline subthalamic nucleus neurons. These neurons were found to contain inten...

In this work, an array of electromechanical systems driven by electrical line Fitzhugh-Nagumo neurons is analyzed. It shown that a single system can display different dynamical behaviors such as and multiple pulse generation, transient permanent chaos, antimonotonicity according to the parameters. case constituted series coupled discrete neurons, numerical simulation shows action potential flow...

Molecules antigenically similar to agrin, a protein extracted from the electric organ of Torpedo californica, are highly concentrated in the synaptic basal lamina of neuromuscular junctions in vertebrate skeletal muscle. On the basis of several lines of evidence it has been proposed that agrin-like molecules mediate the nerve-induced formation of acetylcholine receptor (AChR) and acetylcholines...
