Table 1.
A comparison of brain regions where constitutive adult neurogenesis occurs in vertebrates (see text for references). (+, regions with well-documented constitutive neurogenesis; (+), regions where neurogenesis have been reported occasionally or been induced experimentally; −, region lacking documented adult neurogenesis.)
