The brain exhibits remarkable plasticity^[1] throughout the lifespan^[2]. Studies show that adult neurogenesis^[3,4] occurs in the hippocampus. Several independent groups^[5] have confirmed these findings in both animal models^[6,7] and human post-mortem tissue^[8].

Furthermore, environmental enrichment^[9] and physical exercise^[10,11] have been shown to enhance neurogenesis rates significantly beyond baseline levels observed in sedentary controls^[12].
