Adult gut can generate new neurons August 4th, 2009 The adult lower digestive tract can be stimulated to add neurons to the intestinal system, according to new mouse research in the August 5 issue of The Journal of Neuroscience. The study shows that drugs similar to the neurotransmitter serotonin increase the production of new neurons in the gut. .. ...For more than 40 years, researchers have known that human bowels contain high concentrations of serotonin (5-HT), a neurotransmitter used to regulate intestinal movements. ...The study shows that the 5-HT4 receptor and, by inference, serotonin play vital roles in the regulation of neurons created in the gut after birth... ...Arturo Alvarez-Buylla, PhD, at University of California, San Francisco, an expert in stem-cell neurobiology and developmental neuroscience who was not affiliated with the study, "The finding not only suggests that new enteric neurons can be generated in the adult, but that activation of the serotonin receptor is required for this process," he said. "The enteric nervous system has a very large number of neurons, yet we know very little about their progressive loss during life and whether they can be regenerated."

Hi madelyn,
Would this have an effect as to whether we should pump sinemet into the gut/intestines? paula Quote:

Hi Paula, I do not have a clue about pumping sinemet into the gut. I wonder what effect SSRIs have upon this gut neuronal system, as well as marveling again that the gut has its own "nervous system" neurotransmitters, which has been noted several times on this forum.
