Journal ArticleDOI
Differential effects of global versus local testosterone on singing behavior and its underlying neural substrate
TL;DR: POM is a key site where T acts to activate copulation and increase song rate, an appetitive sexual behavior in songbirds, but T action in other areas of the brain or periphery is required to enhance the quality of song as well as regulate context-specific vocalizations.
Journal ArticleDOI
Aromatase inhibition rapidly affects in a reversible manner distinct features of birdsong.

TL;DR: It is indicated that estrogens also act in a rapid fashion to regulate two distinct features of song, a learned vocal behavior.
Journal ArticleDOI

TL;DR: In this paper, the authors investigated the orchestration by testosterone (T) of birdsong and its neural substrate, the song control system, and found that T in HVC enhanced the incorporation and recruitment of new neurons into this nucleus.
Pleiotropic Control by Testosterone of a Learned Vocal Behavior and Its Underlying
TL;DR: The orchestration by testosterone of birdsong and its neural substrate, the song control system, is investigated, finding that T in HVC enhanced the incorporation and recruitment of new neurons into this nucleus, while singing activity can independently influence the incorporation ofnew neurons into HVC.
Journal ArticleDOI
The regulation of birdsong by testosterone: Multiple time-scales and multiple sites of action.
TL;DR: This work shows that testosterone in the medial preoptic nucleus regulates the motivation to sing, but not aspects of song performance, and testosterone and its estrogenic metabolites regulate distinct features of birdsong depending on the site and temporal window of action.
