The rostromedial tegmental nucleus gates fat overconsumption through ventral tegmental area output in male rats
Excessive consumption of palatable foods that are rich in fats and sugars has contributed to the increasing prevalence of obesity worldwide. Similar to addictive drugs, such foods activate the brain’s reward c...

Hippocampal Cannabinoid 1 Receptors Are Modulated Following Cocaine Self-administration in Male Rats
Cocaine addiction is a complex pathology inducing long-term neuroplastic changes that, in turn, contribute to maladaptive behaviors. This behavioral dysregulation is associated with transcriptional reprogramm...

RSK2 Signaling in Medial Habenula Contributes to Acute Morphine Analgesia
It has been established that mu opioid receptors activate the ERK1/2 signaling cascade both in vitro and in vivo. The Ser/Thr kinase RSK2 is a direct downstream effector of ERK1/2 and has a role in cellular signa...

Effects of delta opioid receptors activation on a response inhibition task in rats
Response inhibition, a primary symptom of many psychiatric disorders, is mediated through a complex neuropharmacological network that involves dopamine, serotonin, glutamate, noradrenaline, and cannabinoid mec...

Open AccessReplicate high-density rat genome oligonucleotide microarrays reveal hundreds of regulated genes in the dorsal root ganglion after peripheral nerve injury.
Rat oligonucleotide microarrays were used to detect changes in gene expression in the dorsal root ganglion (DRG) 3 days following sciatic nerve transection (axotomy). Two comparisons were made using two sets o...

[35S]GTPγS binding: A tool to evaluate functional activity of a cloned opioid receptor transiently expressed in COS cells
In this paper we propose a powerful procedure to measure functional activation of the mouse δ-opioid receptor transiently expressed in mammalian cells. Receptor stimulation was assessed using a population of e...
