Heroin Reduces The Brain’s Ability To Form Synapses

Exposure to heroin sharply reduces levels of the protein necessary for developing and maintaining the brain’s synapses, a preclinical study[1] by University at Buffalo researchers has found. The development of addiction relapse is directly related to the impact that reductions in this protein, called drebrin, have on specific cells involved in the brain’s pleasure-seeking/reward pathways. […]

Nociceptin Neurons Become Active Before Loss Of Motivation

What happens when we give up? Inside the brain, a group of cells known as nociceptin neurons get very active before a mouse’s breakpoint. They emit nociceptin, a complex molecule that suppresses dopamine, a chemical largely associated with motivation. The findings offer new insight into the complex world of motivation and reward. The nociceptin neurons […]

Neonatal Nicotine Exposure Alters Brain’s Reward Circuity

Early life exposure to nicotine alters neurons in the brains of newborn mice, increasing their preference for the drug in later adulthood, researchers at University of California San Diego School of Medicine report. Exposure to nicotine in the first few weeks of life (through maternal lactation) caused a form of neuroplasticity that resulted in increased […]

Mindful Body Awareness Training Helps Prevent Drug Addiction Relapse

A new kind of body awareness training helps women recover from drug addiction, new research from the University of Washington indicates. The women made marked improvements, and many of those improvements lasted for more than a year, the researchers report. “We could teach this intervention successfully in eight weeks to a very distressed population, and […]
