Corn feeding during development induces changes in the number of serotonergic neurons in the raphe nuclei
2003, International Journal of Developmental NeuroscienceCitation Excerpt :Although some authors producing prenatal protein deprivation found no effect of the diet on the timing of hippocampal pyramidal cell generation (DeBassio et al., 1994) or on the number of cells generated in the locus cœrulius (King et al., 1999; Chen et al. (1992)) also using prenatally protein malnourished rats found a significant increase of 5-HT release and 5-HIAA concentration in hippocampal slice preparations when compared to controls with no significant differences in other neurotransmitter concentrations. Blatt et al. (1994) in a neuroanatomical study in protein deprived adult rats found a decrease in the density of 5-HT afferent fibers in the hippocampal formation; and Ishimura et al. (1989) increasing the litter size of mice during the first 3 weeks postnatally with quantitative analysis at 60 postnatal days of age (PND) found a significant decrease in serotonin immunoreactive 5-HT immunoreactive (5-HTir) cell bodies in the total raphe system and the subpyramidal region. Although numerous neurochemical studies have been made in malnourished rats including those employing TRY-restricted diets, there are few studies dealing with changes in the serotonergic system of specific brain regions of nutrient restricted rodents.
