Neurogenesis in the dentate gyrus (DG) of the hippocampus is increased by spatial learning and postnatal stimulation. Conversely, prenatal stress (PS) produces a decrease in the proliferation of hippocampal granular cells. This work evaluated the effect of postnatal tactile stimulation (PTS), when applied from birth to adulthood (3 months old),...

Prenatal stress (PS) in mammals is a factor involved in fetal programming of long term reproductive disorders. When PE is present during critical stages of fetal development it can cause alterations in adrenal and gonadal axes. Currently, it is unknown whether these changes are involved in the neuroendocrine control of...
