RESUMO
The serotoninergic neuronal systems of the brain stem are involved in several processes, like sleep, anxiety and depression. Because of this, these systems have received a great deal of attention during the last few years. As a result, the raphe nuclei have been shown to contain a variety of substances in addition to serotonin. For example they were shown to contain GABA, noradrenaline, enkephalin, somatostatin, substance P and cholecystokinin. Additionally, neuropeptide Y and tirotrophine releasing factor have been found to colocalize with serotonin in the dorsal raphe nuclei. All these results have expanded our knowledge on the raphe nuclei and suggest that many other substances, apart from serotonin, could be involved in the regulation of processes such as sleep, anxiety and depression. Further experiments are necessary to test if this hypothesis is correct.
