Castration modulates singing patterns and electrophysiological properties of RA projection neurons in adult male zebra finches [PDF]
PeerJ, 2014 Castration can change levels of plasma testosterone. Androgens such as testosterone play an important role in stabilizing birdsong. The robust nucleus of the arcopallium (RA) is an important premotor nucleus critical for singing.

Attractive and healthy-looking male faces do not show higher immunoreactivity
Scientific Reports, 2022 Previous research has indicated that facial attractiveness may provide cues to the functioning of the immune system. Mating with individuals who have a more effective immune system could lead to a higher reproductive success.

Sexually selected male plumage color is testosterone dependent in a tropical passerine bird, the red-backed fairy-wren (Malurus melanocephalus). [PDF]
PLoS ONE, 2011 BACKGROUND: Sexual signals, such as bright plumage coloration in passerine birds, reflect individual quality, and testosterone (T) may play a critical role in maintaining signal honesty.

Mechanism of estradiol-induced block of voltage-gated K+ currents in rat medial preoptic neurons. [PDF]
PLoS ONE, 2011 The present study was conducted to characterize possible rapid effects of 17-β-estradiol on voltage-gated K(+) channels in preoptic neurons and, in particular, to identify the mechanisms by which 17-β-estradiol affects the K(+) channels.
