Scientific Basis for Managing PFAS as a Chemical Class

 · This commentary presents a scientific basis for managing as one chemical class the thousands of chemicals known as PFAS (per- and polyfluoroalkyl substances). The class includes perfluoroalkyl acids perfluoroalkylether acids and their precursors fluoropolymers and perfluoropolyethers and other PFAS. The basis for the class approach is presented in relation to their

Neurogenesis the formation of new neurons in the adult brain is important for memory formation and extinction. One of the most studied external interventions that affect the rate of adult neurogenesis is physical exercise. Physical exercise promotes adult neurogenesis via several factors including brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF).
