The Effects of Lidocaine Reversible Inactivation of the Dorsal Raphe Nucleus on Passive Avoidance Learning in Rats
Introduction: The role of serotonergic fibers in avoidance learning is controversial. Involvement of the dorsal raphe nucleus (DRN), the main source of hippocampal projecting serotonergic fibers in acquisition, consolidation and retrieval of passive avoidance (PA) learning, was investigated by functional suppression of this area. Materials and Methods: DRN functional inactivation was done by li...

متن کاملCalretinin in Dorsal Raphe Nucleus of the Chinchilla
The localisation of carletinin in the midbrains of 10 sexually mature chinchilla males was examined by carrying out the peroxidase-antiperoxidase immunocytochemical reaction using specific monoclonal antibody against calretinin. Intensive immunostaining for the protein was observed in the majority of fusiform, pyramidal, and stellate neurons of dorsal raphe nucleus. A similar calretinin distrib...
متن کاملCoding of task reward value in the dorsal raphe nucleus.
The dorsal raphe nucleus and its serotonin-releasing neurons are thought to regulate motivation and reward-seeking. These neurons are known to be active during motivated behavior, but the underlying principles that govern their activity are unknown. Here we show that a group of dorsal raphe neurons encode behavioral tasks in a systematic manner, tracking progress toward upcoming rewards. We ana...
متن کاملMicroarray analyses reveal novel targets of exercise-induced stress resistance in the dorsal raphe nucleus
Serotonin (5-HT) is implicated in the development of stress-related mood disorders in humans. Physical activity reduces the risk of developing stress-related mood disorders, such as depression and anxiety. In rats, 6 weeks of wheel running protects against stress-induced behaviors thought to resemble symptoms of human anxiety and depression. The mechanisms by which exercise confers protection a...
