2020, Pharmacology Biochemistry and BehaviorCitation Excerpt :Many of the cardinal studies of EE examined the somatosensory cortices. EE consistently increases dendritic complexity (Greenough and Volkmar, 1973; Jung and Herms, 2012; Diamond et al., 1966; Leggio et al., 2005), synaptic plasticity (Briones et al., 2004; Turner and Greenough, 1985; Diamond et al., 1964), and neurotrophins (Torasdotter et al., 1998) in these areas. Similar effects have been noted in the hypothalamus, where EE increases dendritic complexity (Mitra and Sapolsky, 2012), and cerebellum, where EE increases BDNF (Angelucci et al., 2009).
