Topographic organization and chemoarchitecture of the dorsal raphe nucleus and the median raphe nucleus The role of serotonergic systems in regulation of behavioral arousal and sleep-wake cycles
The story of serotonin and sleep has been developing for more than 50 years, from the discovery in the 1950s that it had a role in brain function and in EEG synchronization. In parallel, the areas of sleep research and neurochemistry have seen enormous developments. The concept of serotonin as a sleep neurotransmitter was based on the effects of lesions of the brainstem raphe nuclei and the eff...
متن کاملAnatomic and functional topography of the dorsal raphe nucleus.
Serotonergic systems play an important and generalized role in regulation of sleep-wake states and behavioral arousal. Recent in vivo electrophysiologic recording studies in animals suggest that several different subtypes of serotonergic neurons with unique behavioral correlates exist within the brainstem raphe nuclei, raising the possibility that topographically organized subpopulations of ser...

15 صفحه اولThe 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 کاملThe effect of desmopressin infusion into dorsal raphe nucleus on pain modulation and morphine analgesia in rats tail flick reflex
Recent neuroanatomical and behavioral evidence has indicated that vasopressin (VA) increases pain threshold. The dorsal raphe nucleus (DRN) is an important nucleus in pain modulation. Anatomical studies have shown that DRN receives vasopressinergic fibers originating in the hypothalamic paraventricular nucleus. The aim of the present study was to examine the effects of intra-DRN injection of de...
