“…The finding that only the medial portion of the cup of RA appears to receive a projection from POM supports this possibility. Interestingly, previous reports have identified a discrete, topographically similar area medial to RA to be innervated with vasotocin fibers in dark-eyed juncos (Junco hyemalis; Panzica et al 1999), and to contain tyrosine hydroxylase (TH) immunoreactive fibers in canaries (Appeltants et al 2001). Together these findings suggest that the cup of RA might be comprised of neurochemically and neuroanatomically distinct subdivisions.…”

Neuroanatomical evidence for indirect connections between the medial preoptic nucleus and the song control system: possible neural substrates for sexually motivated song

In European starlings ( Sturnus vulgaris) as in other seasonally breeding songbirds, a major function of song during the breeding season is mate attraction, and song in this context is highly sexually motivated. Song learning, perception, and production are regulated by nuclei of the song control system, but there is no evidence that these nuclei participate in the motivation to sing. Evidence suggests that the medial preoptic nucleus (POM), a diencephalic nucleus outside of the song control system, might regulate the motivation to sing, at least in a sexual context. If the POM is involved in the regulation of sexually motivated song, then this structure must interact with the song control system. To examine possible neuroanatomical connections between the POM and song control nuclei a tract-tracing study was performed in male starlings using the antero- and retrograde tract tracer, biotinylated dextran amine (BDA). No direct connections were identified between the POM and song control nuclei; however, labeled fibers were found to terminate in a region bordering dorsal-medial portions of the robust nucleus of the archistriatum (RA). Additionally, several indirect routes via which the POM might communicate with the song control system were identified. Specifically, POM projected to dorsomedial nucleus intercollicularis (DM), mesencephalic central gray (GCt), area ventralis of Tsai (AVT), and locus ceruleus (LoC), structures projecting directly to nuclei involved in song production (DM --> vocal-patterning and respiratory nuclei; GCt, AVT, LoC --> RA and HVC, and the context in which song is sung (AVT --> area X). These results are consistent with the possibility that the POM regulates sexually motivated song through interactions with brain regions involved in vocal production.

“…In most species except mammals, orexin-ir cells also are periventricular and associated with neurosecretory areas. Indeed, in birds, the rostral PVN contains neurosecretory cells (Panzica et al, 1982;Kiss et al, 1987;Voorhuis and deKloet, 1992;Panzica et al, 1999;Absil et al, 2002). In fish and amphibians, neurosecretory cells are found in the POA and SCN (Goossens et al, 1977;Conway and Gainer, 1987;Smeets and González, 2001;Duarte et al, 2001).…”

“…Notably, recent studies have provided much-needed information on various behavioral functions of the avian PAG and adjacent tegmentum (Shaw, 2000;Maney and Ball, 2003;Charlier et al, 2005). These tracings and functional studies have been conducted concomitantly with a large number of immunocytochemical studies, particularly focused on the distribution of neuropeptides and/or their regulation by sex steroids (Aste et al, 1991(Aste et al, , 1995(Aste et al, , 1997(Aste et al, , 1998aPanzica et al, 1998Panzica et al, , 1999bGoodson et al, 2004a;Plumari et al, 2004). Overall, the data strongly support the proposal that birds possess a "social behavior network" that is homologous to the network identified for mammals (Goodson, 2005; for a more general consideration of the avian forebrain, see Reiner et al, 2004).…”

Ever since investigations in the field of behavioral endocrinology were hatched with experiments on roosters, birds have provided original insights into issues of fundamental importance for all vertebrate groups. Here we focus on more recent advances that continue this tradition, including 1) environmental regulation of neuroendocrine and behavioral systems, 2) steroidogenic enzyme functions that are related to intracrine processes and de novo production of neurosteroids, and 3) hormonal regulation of neuroplasticity. We also review recent findings on the anatomical and functional organization of steroid-sensitive circuits in the basal forebrain and midbrain. A burgeoning body of data now demonstrates that these circuits comprise an evolutionarily conserved network, thus numerous novel insights obtained from birds can be used (in a relatively straightforward manner) to generate predictions for other taxa as well. We close by using birdsong as an example that links these areas together, thereby highlighting the exceptional opportunities that birds offer for integrative studies of behavioral neuroendocrinology, and behavioral biology in general.

Indeed, wild birds offer a combination of accessibility (being diurnal and terrestrial) and diversity (social and ecological) that makes them invaluable models for studying mechanistic and evolutionary questions that are not as tractable in other vertebrate groups. This diversity can be studied within the context of neural and endocrine systems that share many features with those of other taxa (thereby increasing the general relevance of avian studies) (Goodson, 2005), although these features are often more pronounced in birds. Such examples include exceptionally robust and widespread neural aromatase activity, and adult neurogenesis in the forebrain, both of which are considered further below (also see Ball and Balthazart, 2004;
