Drugs acting through 5-HT (5-hydroxytryptamine, or serotonin) systems modulate memory and its alterations, but the mechanisms by which they do so are poorly understood. Agonists and antagonists for 5-HT receptors, as well as serotonin uptake inhibitors, present promnesic (memory-promoting) and/or anti-amnesic effects under different conditions, and 5-HT receptors are also associated with neural changes. The Role of 5-HT Systems on Memory and Dysfunctional Memory: Emergent Targets for Memory Formation and Memory Alterations reviews and summarizes the most recent research related to...
