Disrupting memories associated with environmental cues significantly reduces cocaine seeking behaviors in rat models of addiction, a new study reports.
A new study suggests sheds light on how cocaine rewires the brain, even after withdrawal.
Scientists used an electronic prosthetic system to tap into existing circuitry in the brain at the cellular level and record the firing patterns of multiple neurons in the prefrontal cortex, the part of the brain involved in decision-making. They then “played” that recording back to the same brain area to electrically stimulate decision-based neural activity. Not only did it restore function, in some cases, it also improved it.
Researchers have found a diverse array of illicit drugs, including cocaine and ketamine, along with pesticides and pharmaceutical chemicals in British freshwater shrimp. While the concentrations of chemicals were considered low, researchers state there is a concern for the potential environmental risk this may pose to wildlife.
Chronic cocaine use alters the epigenetic profile of the FosB gene in the hippocampus. These alterations are required for cocaine-dependent gene expression and cocaine environment associations. Modification of hippocampal FosB results in a condition critical for cocaine-related learning.
Researchers report 10 percent of people who have attended EDM events have misused opioids in the past 12 months. The number, researchers say, exceeds national averages. Oxycontin was reported to be the most widely misused drug within the scene.
A new study reports repetitive transcranial magnetic stimulation appears to reduce cocaine use and cravings in those addicted to the drug.
Cannabis use during youth enhances sensitivity to cocaine from the first exposure, a new rat study finds.
A new study brings researchers one step closer to unlocking the mysteries of sleep.
