Abstract Addictive drugs hijack the neuronal mechanisms of learning and memory in motivation and emotion processing circuits to reinforce their own use. Regulator of G-protein Signaling 14 (RGS14) is a natural suppressor of post-synaptic plasticity underlying learning and memory in the hippocampus. The present study used immunofluorescence and RGS14 knockout mice to assess the role of RGS14 in behavioral plasticity and reward learning induced by chronic cocaine in emotional-motivational circuits.

Karne, Sergi Ferré, David Weinshenker doi: https://doi.org/10.1101/2021.01.31.428998 ABSTRACT The neuropeptide galanin is reported to attenuate opioid withdrawal symptoms, potentially by reducing neuronal hyperactivity in the noradrenergic locus coeruleus (LC) via galanin receptor 1 (GalR1).

I spotted the iconic 660-foot front porch of the Grand Hotel from the ferry to Mackinac Island. From a distance I could see the massive white structure on a hill in stark contrast to the deep green of the surrounding trees and the rich blue waters of Lake Huron. As we approached the structure took shape; Victorian architecture, bright yellow awnings and hanging American flags complimented an endless garden of blooming flowers.
