Post-embryonic neurogenesis is a fundamental feature of the vertebrate brain. However, the
level of adult neurogenesis decreases significantly with phylogeny. In the first part of this …

Over the past two decades, evidence has accumulated that neurogenesis can occur in both
the juvenile and adult mammalian hypothalamus. Levels of hypothalamic neurogenesis can …

Lifelong neurogenesis in vertebrates relies on stem cells producing proliferation zones that
contain neuronal precursors with distinct fates. Proliferation zones in the adult zebrafish …

Seasonal changes in the neural attributes of brain nuclei that control song in songbirds are
among the most pronounced examples of naturally occurring plasticity in the adult brain of …

The walls of the cerebral ventricles in the developing embryo harbor the primary neural stem
cells from which most neurons and glia derive. In many vertebrates, neurogenesis continues …

Neurogenesis continues in the brain of adult birds. These cells are born in the ventricular
zone of the lateral ventricles. Young neurons then migrate long distances guided, in part, by …

Although evidence accumulated during the last decades has advanced our understanding
of adult neurogenesis in the vertebrate brain, many aspects of this intriguing phenomenon …

Adult male canaries modify their song every year. Most of these changes occur during late
summer and early fall, after the end of the breeding season, and in late winter, immediately …

New neurons are added to the high vocal center (HVC) of adult male and female canaries.
Exogenous testosterone induces a marked increase in HVC size in adult female canaries …

The discovery of spontaneous neuronal replacement in the adult vertebrate brain has
changed the way in which we think about the biology of memory. This is because neuronal …
