J Comp Neurol 511:173-86. 2008..Our results demonstrate a possible mechanism by which gonadal steroids may alter the processing of social signals and affect social decision-making... - Endocrine and genomic architecture of life history trade-offs in an avian model of social behaviorDonna L Maney
Department of Psychology, Emory University, 532 Kilgo Circle, Atlanta, GA 30322, USA
Gen Comp Endocrinol 157:275-82. 2008..Overall, the white-throated sparrow represents an ideal model in which to study the genetic and endocrine bases of life history strategies and their evolution... - Rapid neuroendocrine responses to auditory courtship signalsDonna L Maney
Department of Psychology, Emory University, 532 Kilgo Circle, Atlanta, GA 30322, USA

Eur J Neurosci 23:1523-9. 2006..E2-dependent plasticity of auditory pathways and processing centres may promote recognition of and attention to conspecific song during the breeding season... - Neuroendocrine correlates of behavioral polymorphism in white-throated sparrowsDonna L Maney
Department of Psychology, Emory University, 532 Kilgo Circle, Atlanta, GA 30322, USA
Horm Behav 48:196-206. 2005..Our results support the hypothesis that differences in these neuropeptide systems underlie inter- and intraspecific differences in social behavior across vertebrates... - Fos-like immunoreactivity in catecholaminergic brain nuclei after territorial behavior in free-living song sparrowsDonna L Maney
Department of Psychological and Brain Sciences, Johns Hopkins University, Baltimore, Maryland 21218, USA
J Neurobiol 56:163-70. 2003..The number of flights directed at the intruder was correlated with FLI in AVT but not GCt. These results suggest a role for AVT and GCt, and thus possibly catecholamines, in the regulation of territorial behavior in songbirds... - Immediate early gene response to hearing song correlates with receptive behavior and depends on dialect in a female songbirdD L Maney
Department of Psychological and Brain Sciences, Johns Hopkins University, Baltimore, MD, USA
J Comp Physiol A Neuroethol Sens Neural Behav Physiol 189:667-74. 2003..This study provides the first evidence that the ZENK response in a sensory area to a social stimulus is proportional to the animal's preference for the stimulus... - Topography of estradiol-modulated genomic responses in the songbird auditory forebrainSara E Sanford
Department of Psychology, Emory University, Atlanta, Georgia 30322, USA
Dev Neurobiol 70:73-86. 2010..Activity in rostral NCM may therefore be seasonally regulated in this species... - Evolution of a bitter taste receptor gene cluster in a New World sparrowJamie K Davis
Department of Human Genetics, Emory University School of Medicine, Atlanta, Georgia, USA
Genome Biol Evol 2:358-70. 2010..These results suggest that interspecies and intraspecies genetic variability does exist in avian TAS2Rs and that these differences could contribute to variation in bitter taste perception in birds... - Activity of the hypothalamic-pituitary-gonadal axis differs between behavioral phenotypes in female white-throated sparrows (Zonotrichia albicollis)Jessica I Lake
Department of Psychology, Emory University, Atlanta, GA 30322, USA
Gen Comp Endocrinol 156:426-33. 2008..We hypothesize that the differences in GnRH-ir cell number and size are related to differences in LH and E2 secretion, and may be relevant to polymorphic social behavior... - Gonadal steroid receptor mRNA in catecholaminergic nuclei of the canary brainstemD L Maney
