Hippocampal long-term potentiation (LTP) is widely considered as a cellular model for learning and memory formation. We have shown previously that protein synthesis-independent, early dentate gyrus (DG) LTP, lasting approximately 4-5 h, can be transformed into a late-LTP with a duration of > or = 24 h by a brief acute swim stress experience (high-stress condition). This reinforcement requires t...
Impairment of attention and memory in patients with Alzheimer's disease (AD) is associated with significantly lower levels of acetylcholine. Inhibition of the breakdown of acetylcholine by blocking the enzymes acetylcholinesterase and butyrylcholinesterase with rivastigmine improves this cholinergic depletion. Thus rivastigmine administration provides established, effective, long-term symptomat...
Despite having pathological changes in the brain associated Alzheimer's disease (AD), some patients have preserved cognitive function. A recent epidemiological study has shown that diet, exercise, cognitive training, and vascular risk monitoring interventions may reduce cognitive decline in at-risk elderly people in the general population. However, the details of molecular mechanisms underlying...
Some studies have shown that acetylcholine muscarinic receptors involved in the opiate reward. In the present study, the effect of intra-basolateral amygdale (BLA) acetylcholine muscarinic like receptor agonist (physostigmine) and antagonist (atropine) on the acquisition of morphine-induced place preference has been investigated in male Wistar rats. For this purpose, two 22 gauges guide cannula...
OBJECTIVES To determine the effect of acetylcholine (ACh), pilocarpine, and atropine on pain evoked responses of pain excited neurons (PEN) and pain inhibited neurons (PIN) in hippocampal CA3 region of morphine addicted rats. MATERIALS AND METHODS Female Wistar rats, weighing between 230-260 g were used in this study. Morphine addicted rats were generated by subcutaneous injection of increasi...
