   Abstract : Anabolic-androgenic steroids (AAS) have been used in clinics for decades. The misuse of AAS has previously been attributed merely to sport athletes, taking AAS with intentions to increase muscle mass, enhance physical performance and to improve results in competitions. READ MORE

7. 5. On cholinergic mechanisms involved in ethanol reinforcement. A behavioral and neurochemical study in rodents

   Author : Anna Larsson; Göteborgs universitet; []
   Keywords : Acetylcholine; Dopamine; Ethanol; Locomotor activity; Microdialysis; Nicotine; Nicotinic acetylcholine receptors; Rodents; Reward;

   Abstract : Alcohol (ethanol) and smoking (nicotine) are commonly co-abused in human beings. Drugs of abuse interact with the brain mesolimbic dopamine system, an important part of the brain reward system. These dopaminergic neurons originate in the ventral tegmental area and project to e.g. READ MORE
