“…These neurons are the evolutionary precursors of peptidergic neurons in the paraventricular hypothalamus of Chemoarchictural themes of the social behavior network as exemplified in songbirds (photomontage of a female zebra finch brain at the level of the anterior commissure; AC). Immunohistochemical triple-labelling for vasoactive intestinal polypeptide (VIP; Alexa Fluor 488, green), neuropeptide Y (NPY; Alexa Fluor 594, red) and tyrosine hydroxylase (TH; Alexa Fluor 350, pseudocolored purple) shows the location of multiple zones of the lateral septum (LS) and bed nucleus of the stria terminalis (BST) that are now known to be extensively comparable to mammals (see Aste et al, 1998;Goodson et al, 2004a;Richard et al, 2004). This labeling also clearly shows the medial and lateral divisions of the ventromedial hypothalamus (i.e., VMH core and shell, respectively), which exhibit a similar topography Functional themes of the lateral septum (LS) as exemplified by findings in wild-caught, territorial male song sparrows (Melospiza melodia; A-B) and field sparrows (Spizella pusilla; C-D).…”

Based on a wide variety of data, it is now clear that the brains of birds and teleost (bony) fish possess a core "social behavior network" within the basal forebrain and midbrain that is homologous to the social behavior network of mammals. The nodes of this network are reciprocally connected, contain receptors for sex steroid hormones, and are involved in multiple forms of social behavior. Other hodological features and neuropeptide distributions are likewise very similar across taxa. This evolutionary conservation represents a boon for experiments on phenotypic behavioral variation, as the extraordinary social diversity of teleost fish and songbirds can now be used to generate broadly relevant insights into issues of brain function that are not particularly tractable in other vertebrate groups. Two such lines of research are presented here, each of which addresses functional variation within the network as it relates to divergent patterns of social behavior. In the first set of experiments, we have used a sexually polymorphic fish to demonstrate that natural selection can operate independently on hypothalamic neuroendocrine functions that are relevant for 1) gonadal regulation and 2) sex-typical behavioral modulation. In the second set of experiments, we have exploited the diversity of avian social organizations and ecologies to isolate species-typical group size as a quasiindependent variable. These experiments have shown that specific areas and peptidergic components of the social behavior network possess functional properties that evolve in parallel with divergence and convergence in sociality.

The first of these goals is to elucidate evolutionary themes in the neuroendocrine, functional, and connectional organization of brain circuits that regulate social behavior. This will provide a phylogenetically broad framework for examining the neural and neuroendocrine mechanisms of behavior, and will allow detailed and meaningful comparisons to be made across the major vertebrate classes. Building upon this foundation, the second primary goal is to capitalize on the extraordinary behavioral diversity of birds and teleost (bony) fish to elucidate the ways that neural and neuroendocrine mechanisms are adjusted over evolutionary time to produce intraspecific and interspecific variation in behavior. If conducted within a well-characterized, comparative framework, these findings obtained in birds and fish should yield solid predictions for other vertebrates as well. Thus, our work addresses evolutionary themes, as described in the first section below, and variations on those themes, as...

“…The reduced amount of proCRF mRNA suggests a decreased synthesis. It is possible that the amount of CRF peptide is also lowered in the paraventricular nucleus (PVN), but that this effect is masked by the presence of other pools of CRF peptide in the total diencephalon (Richard et al 2004). In addition, the lack of feedback effects at the CRF peptide level in the ME suggests that, in chickens, glucocorticoids do not influence the secretion of CRF from the ME.…”

This paper reports the results of in vivo and in vitro experiments on the feedback effects of corticosterone on the hypothalamo-pituitary-adrenal axis in embryos at day 18 of incubation and in 9-day-old chickens. In vivo, a significant negative feedback was detected on the levels of corticotropin-releasing factor (CRF) precursor (proCRF) mRNA and on the plasma concentration of corticosterone, two hours after a single intravenous injection with 40 µg corticosterone. In contrast, the levels of CRF peptide in the hypothalamic area, the CRF receptor type 1 (CRF-R1) mRNA and pro-opiomelanocortin (POMC) mRNA levels in the pituitary were not affected by the in vivo administration of corticosterone. In vitro, incubation with 1 µM corticosterone did not affect the CRF-R1 mRNA levels in the pituitary, but significant feedback inhibition was observed on the POMC mRNA levels. These in vitro effects were the same at the two ages studied. The in vitro feedback effect on the proCRF gene expression, however, differed with age. In 9-day-old animals a decrease in gene expression was observed which was not detectable in embryonic tissue at day 18 of the ontogeny.

Neurons containing these neuropeptides are found in the BSTLd of quail, chicken and pigeon [Reiner et al, 1984;Molnar et al, 1994;Richard et al, 2004;Martínez-García et al, 2008;Abellán and Medina, 2009;Vicario et al, 2014] as well as in the murine BSTL [Moga et al, 1989;Gray and Magnuson, 1992].

In a recent study, we tentatively identified different subdivisions of the central extended amygdala (EAce) in chicken based on the expression of region-specific transcription factors (including Pax6 and Islet1) and several phenotypic markers during embryonic development. Such a proposal was partially based on the suggestion that, similarly to the subdivisions of the EAce of mammals, the Pax6 and Islet1 neurons of the comparable chicken subdivisions derive from the dorsal (Std) or ventral striatal embryonic domains (Stv), respectively. To investigate whether this is true, in the present study, we carried out cell migration assays from chicken Std or Stv combined with immunofluorescence for Pax6 or Islet1. Our results showed that the cells of the proposed chicken EAce truly originate in either Std (expressing Pax6) or Stv (expressing Islet1). This includes lateral subdivisions previously compared to the intercalated amygdalar cells and the central amygdala of mammals, also rich in Std-derived Pax6 cells and/or Stv-derived Islet1 cells. In the medial region of the chicken EAce, the dorsal part of the lateral bed nucleus of the stria terminalis (BSTL) contains numerous cells expressing Nkx2.1 (mostly derived from the pallidal domain), but our migration assays showed that it also contains neuron subpopulations from the Stv (expressing Islet1) and Std (expressing Pax6), resembling the mouse BSTL. These findings, together with those previously published in different species of mammals, birds and reptiles, support the homology of the chicken EAce to that of other vertebrates, and reinforce the existence of several cell subcorridors inside the EAce. In addition, together with previously published data on neuropeptidergic cells, these results led us to propose the existence of at least seventeen neuron subtypes in the EAce in rodents and/or some birds (chicken and pigeon). The functional significance and the evolutionary origin of each subtype needs to be analyzed separately, and such studies are mandatory in order to understand the multifaceted modulation by the EAce of fear responses, ingestion, motivation and pain in different vertebrates.
