Based on a wide variety of data, it is now clear that birds and teleost (bony) fish possess a
core “social behavior network” within the basal forebrain and midbrain that is homologous to …

Early 20th‐century comparative anatomists regarded the avian telencephalon as largely
consisting of a hypertrophied basal ganglia, with thalamotelencephalic circuitry thus being …

The standard nomenclature that has been used for many telencephalic and related
brainstem structures in birds is based on flawed assumptions of homology to mammals. In …

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 …

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 …

It has become increasingly clear that the standard nomenclature for many telencephalic and
related brainstem structures of the avian brain is based on flawed once‐held assumptions of …

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 organization of the pigeon hippocampal formation was examined by tract tracing by
using biotinylated dextran amine (BDA) and cholera toxin B subunit (CTB) and by injections …

In many species, territoriality is expressed only during the breeding season, when plasma
testosterone (T) is elevated. In contrast, in song sparrows (Melospiza melodia morphna) …
