Microinjection of WIN55,212-2 as a Cannabinoid Agonist into the Basolateral Amygdala Induces Sensitization to Morphine in Rats
Introduction: Previous studies have shown that the basolateral amygdale (BLA) is rich of CB1 cannabinoid receptors and involved in cannabinoid-induced antinociception. Also, it seems that there are functional interactions between the cannabinoid CB1 and opioid receptors in the process of sensitization to opiates. In the present study, we tried to examine the role of intra-BLA cannabinoid rece...
متن کاملGlutamate Receptors in Nucleus Accumbens Can Modulate Canabinoid-Induced Antinociception in Rat’s Basolateral Amygdala
Introduction: It has been shown that administration of WIN55,212-2, a cannabinoid receptor agonist, into the basolateral amygdala (BLA), dose-dependently increases the thermal latency to withdrawal in the tail-.ick test and decreases pain related behaviors in both phases of the formalin test. Recent human and animal imaging data suggest that the nucleus accumbens (NAc) is an important neural su...
متن کاملThe role of acetylcholine muscarinic receptors in the rat basolateral amygdala on morphine-induced place preference
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...

متن کاملBasolateral amygdala and morphine-induced taste avoidance in the rat.
The present experiment examined the influence of excitotoxic lesions of the basolateral amygdala (BLA) on morphine-induced saccharin avoidance. Neurologically intact subjects rapidly learned to avoid drinking the taste conditioned stimulus (CS), an effect that was sustained throughout the experiment. Although the BLA-lesioned (BLAX) rats showed CS avoidance over the first few trials, the effect...
