چکیده

the serotonin (5-ht) receptors are a group of g protein-coupled receptors (gpcrs) and ligand-gated ion channels that found in the central and peripheral nervous systems. 5ht receptor can substantially influence brain functions such as learning and memory, perception of the environment, mood states, and responses to alcohol and other drugs of abuse. lysergic acid diethylamide (lsd) as a 5ht receptor agonist causes expansion and an altered experience of senses, emotions, memories, time, and awareness. as we know closed head injuries are usually caused by blows to the head and frequently occur in traffic accidents, falls and assaults and leads to some disorders like spatial memory dysfunctions. acute treatments of adult 8-week-old male wistar rats with agonists of 5-ht receptor subtypes were followed by a single injection of 5'-bromodeoxyuridine (200 mg/kg, i.p.) 2 h before killing to examine the effect of these drugs specifically on spatial memory rehabilitation. our data showed that lsd can promote rehabilitation of spatial memory dysfunction after closed head injury.

Impairment of remote memory after closed head injury.

Evidence of partial retrograde amnesia for episodic memories of no personal salience was found in head injured patients (n = 10) tested during posttraumatic amnesia or shortly after its resolution (n = 10), but there was no selective preservation of the earliest memories. In contrast, head injured patients tested during posttraumatic amnesia exhibited relatively preserved retention of early aut...

Effect of Selective 5-HT6R Agonist on Expression of 5-HT Receptor and Neurotransmitter in Vascular Dementia Rats

BACKGROUND 5-HT6 receptor (5-HT6R) has pluripotent roles regulating secretion of neurotransmitters. However, whether 5-HT6R is involved in the development of vascular dementia (VD) remains unclear. To evaluate the role and mechanism of 5-HT6R in VD, this study established a rat VD model to evaluate the effect of selective 5-HT6R agonist on the expression of 5-HT6R mRNA and neurotransmitter. MAT...
