Anseriform birds (ducks and geese) as well as parrots and songbirds have evolved a
disproportionately enlarged telencephalon compared with many other birds. However …

The mammalian hippocampus, a center of neurogenesis in the adult brain, is involved in
critical functions such as learning and memory processing. Although there is an overall …

It has been reported that neurons generated in the adult brain show sex‐specific differences
in several brain regions of lower vertebrates and mammals. The present study questioned …

Cell proliferation, differentiation and cell death are considered key players for brain plasticity
mechanisms that underlie sex specific phenotypes in brain and behavior. Well-documented …

Previous work in songbirds has suggested that testosterone increases neuronal recruitment
and survival in HVC but does not affect neuronal proliferation in the ventricular zone and that …

Background The relative size and neuronal density of brain regions are important metrics in
both comparative and experimental studies in neuroscience. Consequently, it is imperative …

Neural proliferation is a conserved property of the adult vertebrate brain. In mammals, stress
reduces hippocampal neuronal proliferation and the effect is stronger in males than in …

Several brain areas in the diencephalon are involved in the activation and expression of
sexual behavior, including in quail the medial preoptic nucleus (POM). However, the …

Most avian neurogenesis studies have previously focused on the song control system and
little attention has been given to non‑song birds. The objective of this study was to assess …

Cellular proliferation within the ventricular zone (VZ) may contribute to sex differences
through the net addition of neurons in song control nuclei. To address this issue, we …
