“…Therefore, this served as our guide for selection of additional hypothalamic brain regions, which included paraventricular (PVN) and ventromedial hypothalamic nuclei (VMN; Figure 1C,D) as well as the lateral (LH) and tuberal hypothalamic regions (TU; Figure 1C,D). Brain punches of these regions were based on Stokes neuroanatomical atlas 53 as well as brain regions illustrated in Reference 63. Figure 1A,B illustrate punches that were included in Next Generation Sequencing (NGS) of the POA.…”

Prolactin is often referred to as the “parental hormone” but there are examples in which prolactin and parental behavior are disconnected. One intriguing example is in avian obligate brood parasites; species exhibiting high circulating prolactin but no parental care. To understand this disconnect, we examined transcriptional and behavioral responses to prolactin in brown‐headed (Molothrus ater) and bronzed (M aeneus) brood parasitic cowbirds. We first examine prolactin‐dependent regulation of transcriptome wide gene expression in the preoptic area (POA), a brain region associated with parental care across vertebrates. We next examined prolactin‐dependent abundance of seven parental care‐related candidate genes in hypothalamic regions that are prolactin‐responsive in other avian species. We found no evidence of prolactin sensitivity in cowbirds in either case. To understand this prolactin insensitivity, we compared prolactin receptor transcript abundance between parasitic and nonparasitic species and between prolactin treated and untreated cowbirds. We observed significantly lower prolactin receptor transcript abundance in brown‐headed but not bronzed cowbird POA compared with a nonparasite and no prolactin‐dependent changes in either parasitic species. Finally, estrogen‐primed female brown‐headed cowbirds with or without prolactin treatment exhibited significantly greater avoidance of nestling begging stimuli compared with untreated birds. Taken together, our results suggest that modified prolactin receptor distributions in the POA and surrounding hypothalamic regions disconnect prolactin from parental care in brood parasitic cowbirds.

“…Schematic drawings of the transverse sections of the brain of T. guttata were prepared using CorelDraw 12 software (Ottawa, Canada). The terminology and identification of the areas of the brain and cell nuclei were adopted from previous studies on birds (Avian nomenclature forum: Reiner et al, ; Stereotaxic atlas of the brain of canary, Serinus canaria : Stokes et al, ; chicken: Kuenzel and Masson, ; Puelles et al, ; terminology outlined by Montagnese et al, for the brain of the blue tit, Cyanistes coeruleus ; brain atlas of crow: Izawa and Watanabe, ; and the digital: Karten et al, , and stereotaxic: Nixdorf‐Bergweiler and Bischof, , atlas of the zebra finch brain). The nomenclature of the septal subdivisions was adopted from the chemoarchitectonic subdivisions of the songbird septum (Goodson et al, ) and nucleus accumbens as described by Alger et al ().…”

Cocaine- and amphetamine-regulated transcript (CART) has emerged as a potent anorectic agent. CART is widely distributed in the brain of mammals, amphibians, and teleosts, but the relevant information in avian brain is not available. In birds, CART inhibits food intake, whereas neuropeptide Y (NPY), a well-known orexigenic peptide, stimulates it. How these neuropeptides interact in the brain to regulate energy balance is not known. We studied the distribution of CART-immunoreactivity in the brain of zebra finch, Taeniopygia guttata, its interaction with NPY, and their response to dynamic energy states. CART-immunoreactive fibers were found in the subpallium, hypothalamus, midbrain, and brainstem. Conspicuous CART-immunoreactive cells were observed in the bed nucleus of the stria terminalis, hypothalamic paraventricular, supraoptic, dorsomedial, infundibular (IN), lateral hypothalamic, Edinger-Westphal, and parabrachial nuclei. Hypothalamic sections of fed, fasted, and refed animals were immunostained with cFos, NPY, and CART antisera. Fasting dramatically increased cFos- and NPY-immunoreactivity in the IN, followed by rapid reduction by 2 hours and restoration to normal fed levels 6-10 hours after refeeding. CART-immunoreactive fibers in IN showed a significant reduction during fasting and upregulation with refeeding. Within the IN, double immunofluorescence revealed that 94 ± 2.1% of NPY-immunoreactive neurons were contacted by CART-immunoreactive fibers and 96 ± 2.8% NPY-immunoreactive neurons expressed cFos during fasting. Compared to controls, superfused hypothalamic slices of fasted birds treated with CART-peptide showed a significant reduction (P < 0.001) in NPY-immunoreactivity in the IN. As in other vertebrates, CART in the brain of T. guttata may perform several functions, and has a particularly important role in the hypothalamic regulation of energy homeostasis. J. Comp.

“…The Avian Brain Nomenclature Consortium (Reiner, Perkel, Mello, & Jarvis, ) proposed several arcopallial subdivisions, consisting of anterior, intermediate, dorsal, and medial parts, as well as the posterior pallial amygdala (PoA), subpallial amygdaloid area (SpA), and nucleus taenia of the amygdala (TnA). Furthermore, some studies provide evidence that discrete arcopallial areas can be identified through immunohistochemical staining for select markers like neuropeptides (e.g., Montagnese, Szekely, Csillag, & Zachar, ), or differential regional binding of ligands for neurotransmitter receptors (Herold et al, ). In some cases, discrete arcopallial nuclei that participate in specific circuits and/or functions are readily identifiable.…”

The arcopallium, a key avian forebrain region, receives inputs from numerous brain areas and is a major source of descending sensory and motor projections. While there is evidence of arcopallial subdivisions, the internal organization or the arcopallium is not well understood. The arcopallium is also considered the avian homologue of mammalian deep cortical layers and/or amygdalar subdivisions, but one‐to‐one correspondences are controversial. Here we present a molecular characterization of the arcopallium in the zebra finch, a passerine songbird species and a major model organism for vocal learning studies. Based on in situ hybridization for arcopallial‐expressed transcripts (AQP1, C1QL3, CBLN2, CNTN4, CYP19A1, ESR1/2, FEZF2, MGP, NECAB2, PCP4, PVALB, SCN3B, SCUBE1, ZBTB20, and others) in comparison with cytoarchitectonic features, we have defined 20 distinct regions that can be grouped into six major domains (anterior, posterior, dorsal, ventral, medial, and intermediate arcopallium, respectively; AA, AP, AD, AV, AM, and AI). The data also help to establish the arcopallium as primarily pallial, support a unique topography of the arcopallium in passerines, highlight similarities between the vocal robust nucleus of the arcopallium (RA) and AI, and provide insights into the similarities and differences of cortical and amygdalar regions between birds and mammals. We also propose the use of AMV (instead of nucleus taenia/TnA), AMD, AD, and AI as initial steps toward a universal arcopallial nomenclature. Besides clarifying the internal organization of the arcopallium, the data provide a coherent basis for further functional and comparative studies of this complex avian brain region.
