About 10 years ago, a sexually differentiated nucleus was identified in the preoptic area
(POA) of the Japanese quail in the course of studies analyzing the dimorphic mechanisms …

It is currently accepted that most sex differences in brain and behavior do not result from
direct genomic actions, but develop following early exposure to a sexually differentiated …

1. Classic evolutionary models interpret ageing as a cost of reproduction, but evolutionary
research has thus far largely neglected the conceptual links between the evolution of ageing …

Seasonal changes in the brain of songbirds are one of the most dramatic examples of
naturally occuring neuroplasticity that have been described in any vertebrate species. In …

Several studies have suggested dissociations between neural circuits underlying the
expression of appetitive (eg, courtship behavior) and consummatory components (ie …

A system of brain nuclei controls song learning and behavior in zebra finches (Poephila
guttata). The size of song‐control nuclei are much larger in males, which sing, than in …

Male sexual behavior in both field and laboratory settings has been studied in birds since
the 19th century. Birds are valuable for the investigation of the neuroendocrine mechanisms …

The distribution of androgen receptors was studied in the brain of the Japanese quail
(Coturnix japonica), the zebra finch (Taeniopygia guttata), and the canary (Serinus canaria) …

Central testosterone aromatization is required for the activation of both appetitive (ASB) and
consummatory (CSB) male sexual behavior in Japanese quail. There are two major clusters …

In male starlings (Sturnus vulgaris) courtship song plays a critical role in mate attraction.
During the breeding season courtship song occurs prior to copulation and appears to reflect …
