Differential appetite regulation in lines of chickens selected for high and low juvenile body weight: the role of beta-MSH
… published in Neuroscience Letters, Journal of Neuroendocrinology, and Behavioural Brain Research, respectively]

Behavioural and neural dynamics of category learning across the menstrual cycle
… bridges neuroscience, behavioral genetics and neuroendocrinology to provide a comprehensive account of learning and memory across the menstrual cycle, while also providing new methodological directions for the broader study of menstrual cycle effects on cognition.

Androgen aromatization and cytosol estradiol-receptors in the mediation of masculine sexual behavior in Japanese quail
The neuroendocrinology of masculine sexual behavior was examined in Japanese quail selected bi-directionally for adult mating frequency. Experiments were conducted with brain tissues from functionally castrated, High (HM) and Low Mating (LM) line quail to compare (1) the in vivo aromatization of …

On the neuroendocrine regulation of reproduction: Functional characterization and kinetic studies of the lamprey gonadotropin -releasing hormone receptor and cloning and analysis of the cDNA encoding lamprey gonadotropin-releasing hormone-III
… herein contribute to the field of reproductive neuroendocrinology through developing our understanding of ancestral, or ancestral-like characteristics and mechanisms of the HPG axis. This dissertation is divided into two major components: (1) functional characterization and kinetic studies of …

The Molecular Evolution of the Serotonin System in Macaques (MACACA): a Detailed Survey of Four Serotonin-Related Genes
… differences are caused by differences in neuroendocrinology. Therefore, the serotonin system provides one potential mechanism through which evolution may act to shape macaque behavior. In this dissertation, I sequence four genes that are known to influence serotonin functioning and …

Dynamical Systems Analysis of Neural Circuits with Applications to Physiological Processes
… representing a central problem in reproductive neuroendocrinology. Using mathematical modelling, this thesis investigates the dynamical mechanisms underlying neuronal network activity, motivated by the role of the posterodorsal medial amygdala (MePD) as a key modulatory input to the GnRH pulse …

In-vivo analysis of hypothalamic kisspeptin neuron activity patterns
Mammalian reproduction is regulated by the brain, pituitary gland, and gonads. In the brain, gonadotropin-releasing hormone (GnRH) is released to stimulate the pituitary gland. In females, two distinct modes of GnRH secretion are controlled by two populations of hypothalamic kisspeptin neurons …

Endogenous Neurosteroid Hormone Production and Early Oligodendricyte Development
<p>The field of neuroendocrinology grew immensely with the realization that steroid hormone production is not confined to the adrenal and reproductive glands but also occurs in the central nervous system (CNS). Steroids synthesized de novo in the brain and spinal cord are referred to as …

Rethinking Psychosocial and Energetic Influences on Cortisol, Testosterone, and Hormonal Coupling among Jordanian, Syrian, and Indigenous Qom Adolescents
Extreme forms of stress derived from displacement, poverty, and armed conflict exposures may confer lasting changes to the neuroendocrine system and may impact the pace of development for children and adolescents. Evolutionary theorists suggest that early life stressors may accelerate or suppress …

Oligodendrocytes of the adult hypothalamic median eminence
The median eminence (ME) of the hypothalamus is a dynamic structure able to rapidly respond to nutrient availability. Both immature oligodendrocyte precursor cells (OPCs) and mature myelinating oligodendrocytes (MOLs) are found in this region in adults. While proliferation of ME OPCs has been shown …

Oligodendrocytes of the adult median eminence
Oligodendrocytes (OLs) are the myelin forming cells of the CNS. Once thought to be generated exclusively during development, recent advances have shown that new OLs are generated in the adult brain from oligodendrocyte progenitor cells (OPCs) in response to physiologically relevant stimuli such as …

Non-coding RNA genes lost in Prader-Willi Syndrome stabilize target RNAs
Prader-Willi Syndrome (PWS) is a genetic disease that results in abnormal hormone levels, developmental delay, intellectual disability, hypogonadism, and excessive appetite. The disease is caused by a de novo genetic deletion in chromosome 15. While many of the deleted genes have been identified, …

Alterations of central dopamine receptor sensitivity in the spontaneously hypertensive rat
Since the time of the introduction of the spontaneously hypertensive rat (SHR) into medical research, several neuropharmacological studies have been performed on these animals which have been unrelated to their cardiovascular systems. A few of these studies have indicated possible abnormalities in …

Dads matter: causes and consequences of plasticity in paternal care
… after successfully parenting, and the neuroendocrinology of parenting suggests that parenting could reorganize the hormonal landscape and behavior of fathers. Using a controlled longitudinal study, I randomly assigned males to either the experimental (reproduced and parented) or control …
