International Behavioral Neuroscience Society - ninth annual meeting.
The main thrust of the meeting was, as always, basic research in behavioral neuroscience defined in a broad sense. Learning and memory, feeding and drinking, reward mechanisms, development of the CNS, anxiety and stress were the main topics covered. In a public lecture associated with the meeting, Larry Reid (Rensselaer Polytechnic Institute, Troy, NY, USA) reviewed the quite compelling evidence in favor of the effectiveness of naltrexone for preventing relapse in former alcoholics. He also presented preclinical data demonstrating the remarkable effects of naltrexone given together with isradipine (Novartis AG) in blocking the rewarding effects of cocaethylene. This combination of drugs could thereby constitute a treatment for alcoholism complicated by cocaine abuse. Of potential therapeutic interest was also the description of the preclinical pharmacology and a phase II trial of a new cholinesterase inhibitor, methanesulfonyl fluoride (University of Texas). The possible physiological functions of sigma opioid receptors and the pharmacological properties of sigma receptor ligands were discussed at one of the symposia. Among the subjects covered were the potential use of sigma1 antagonists in the treatment of cocaine addiction and the efficiency of sigma1 agonists for preventing the decline in cognitive functions associated with old age.
