Sexual experience also increases circulating glucocorticoid levels (Bonilla-Jaime et al., 2006). Acute sexual experience increases cell proliferation in the dentate gyrus of adult rats (Leuner et al., 2010). Chronic sexual experience increases cell proliferation and adult neurogenesis in the dentate gyrus (Leuner et al., 2010). Learning has also been shown to increase glucocorticoid levels (Leuner et al., 2004) and various studies have shown that training on certain types of learning tasks increases adult neurogenesis (reviewed in Leuner et al., 2006).
