The medial thalamus receives some indirect input through the spinal cord, but Furthermore, it receives a major input from your region in the Mind stem reticular development to which the nociceptive spinoreticular neurons task.

two Additionally it is phosphorylated by G-protein-coupled receptor kinases and binds arrestins, especially when activated by superior-efficacy agonists. There have been extensive discussion about the possible therapeutic benefits of biased agonists that could activate only Some pathways. A further understanding of the conversation concerning the µOR and its ligands could for that reason bring about the development of recent medicines with less Negative effects.
