Neural Circuits Underlying Rodent Sociality: A Comparative Approach, Nicole S. Lee, Annaliese K. Beery Jan 2019

Neural Circuits Underlying Rodent Sociality: A Comparative Approach, Nicole S. Lee, Annaliese K. Beery

Neuroscience: Faculty Publications

All mammals begin life in social groups, but for some species, social relationships persist and develop throughout the course of an individual’s life. Research in multiple rodent species provides evidence of relatively conserved circuitry underlying social behaviors and processes such as social recognition and memory, social reward, and social approach/avoidance. Species exhibiting different complex social behaviors and social systems (such as social monogamy or familiarity preferences) can be characterized in part by when and how they display specific social behaviors. Prairie and meadow voles are closely related species that exhibit similarly selective peer preferences but different mating systems, aiding direct …


Frank Beach Award Winner: Neuroendocrinology Of Group Living, Annaliese K. Beery Jan 2019

Frank Beach Award Winner: Neuroendocrinology Of Group Living, Annaliese K. Beery

Neuroscience: Faculty Publications

Why do members of some species live in groups while others are solitary? Group living (sociality) has often been studied from an evolutionary perspective, but less is known about the neurobiology of affiliation outside the realms of mating and parenting. Colonial species offer a valuable opportunity to study nonsexual affiliative behavior between adult peers. Meadow voles (Microtus pennsylvanicus) display environmentally induced variation in social behavior, maintaining exclusive territories in summer months, but living in social groups in winter. Research on peer relationships in female meadow voles demonstrates that these selective preferences are mediated differently than mate relationships in …


Septal Oxytocin Administration Impairs Peer Affiliation Via V1a Receptors In Female Meadow Voles, Allison M.J. Anacker, Jennifer D. Christensen, Elyssa M. Laflamme, Diana M. Grunberg, Annaliese K. Beery Jun 2016

Septal Oxytocin Administration Impairs Peer Affiliation Via V1a Receptors In Female Meadow Voles, Allison M.J. Anacker, Jennifer D. Christensen, Elyssa M. Laflamme, Diana M. Grunberg, Annaliese K. Beery

Neuroscience: Faculty Publications

The peptide hormone oxytocin (OT) plays an important role in social behaviors, including social bond formation. In different contexts, however, OT is also associated with aggression, social selectivity, and reduced affiliation. Female meadow voles form social preferences for familiar same-sex peers under short, winter-like day lengths in the laboratory, and provide a means of studying affiliation outside the context of reproductive pair bonds. Multiple lines of evidence suggest that the actions of OT in the lateral septum (LS) may decrease affiliative behavior, including greater density of OT receptors in the LS of meadow voles that huddle less. We infused OT …


Natural Variation In Maternal Care And Cross-Tissue Patterns Of Oxytocin Receptor Gene Methylation In Rats, Annaliese K. Beery, Lisa M. Mcewen, Julia L. Macisaac, Darlene D. Francis, Michael S. Kobor Jan 2016

Natural Variation In Maternal Care And Cross-Tissue Patterns Of Oxytocin Receptor Gene Methylation In Rats, Annaliese K. Beery, Lisa M. Mcewen, Julia L. Macisaac, Darlene D. Francis, Michael S. Kobor

Neuroscience: Faculty Publications

Since the first report of maternal care effects on DNA methylation in rats, epigenetic modifications of the genome in response to life experience have become the subject of intense focus across many disciplines. Oxytocin receptor expression varies in response to early experience, and both oxytocin signaling and methylation status of the oxytocin receptor gene (Oxtr) in blood have been related to disordered social behavior. It is unknown whether Oxtr methylation varies in response to early life experience, and whether currently employed peripheral measures of Oxtr methylation reflect variation in the brain. We examined the effects of early life rearing experience …

Fatigue is a disabling symptom in patients with multiple sclerosis and Parkinson’s Disease, and is also common in patients with traumatic brain injury, cancer, and inflammatory disor- ders. Little is known about the neurobiology of fatigue, in part due to the lack of an approach to induce fatigue in laboratory animals. Fatigue is a common response to systemic challenge by pathogens, a response in part mediated through action of the pro-inflammatory cytokine interleukin-1 beta (IL-1β). We investigated the behavioral responses of mice to IL-1β. Female C57Bl/6J mice of 3 ages were administered IL-1β at various doses i.p. Interleukin-1β reduced locomotor …


Chronic Stress Elevates Telomerase Activity In Rats, Annaliese K. Beery, Jue Lin, Joshua S. Biddle, Darlene D. Francis, Elizabeth H. Blackburn, Elissa S. Epel Dec 2012

Chronic Stress Elevates Telomerase Activity In Rats, Annaliese K. Beery, Jue Lin, Joshua S. Biddle, Darlene D. Francis, Elizabeth H. Blackburn, Elissa S. Epel

Neuroscience: Faculty Publications

The enzyme telomerase lengthens telomeres—protective structures containing repetitive DNA sequences at chromosome ends. Telomere shortening is associated with diseases of ageing in mammals. Chronic stress has been related to shorter immune-cell telomeres, but telomerase activity under stress may be low, permitting telomere loss, or high, partially attenuating it. We developed an experimental model to examine the impacts of extended unpredictable stress on telomerase activity in male rats. Telomerase activity was 54 per cent higher in stressed rats than in controls, and associated with stress-related physiological and behavioural outcomes. This significant increase suggests a potential mechanism for resilience to stress-related replicative …


Enhancement And Suppression Of Ultradian And Circadian Rhythms Across The Female Hamster Reproductive Cycle, Brian J. Prendergast, Annaliese K. Beery, Matthew J. Paul, Irving Zucker Jun 2012

Enhancement And Suppression Of Ultradian And Circadian Rhythms Across The Female Hamster Reproductive Cycle, Brian J. Prendergast, Annaliese K. Beery, Matthew J. Paul, Irving Zucker

Neuroscience: Faculty Publications

The impact of ovarian hormones on hamster ultradian rhythms (URs) is unknown. We concurrently monitored URs and circadian rhythms (CRs) of home cage locomotor activity during the estrous cycle, pregnancy, and lactation of Syrian hamsters. URs with a mean period of 4–5 h were evident during the dark phase in more than 90% of females on days 1 and 2 of the estrous cycle but were significantly less prevalent on cycle days 3 and 4. The period of the UR did not vary as a function of estrous cycle stage, but at all stages, the UR period was longer in …


Adaptive Significance Of Natural Variations In Maternal Care In Rats: A Translational Perspective, Annaliese K. Beery, Darlene D. Francis Jun 2011

Adaptive Significance Of Natural Variations In Maternal Care In Rats: A Translational Perspective, Annaliese K. Beery, Darlene D. Francis

Neuroscience: Faculty Publications

A wealth of data from the last fifty years documents the potency of early life experiences including maternal care on developing offspring. A majority of this research has focused on the developing stress axis and stress-sensitive behaviors in hopes of identifying factors impacting resilience and risk-sensitivity. The power of early life experience to shape later development is profound and has the potential to increase fitness of individuals for their environments. Current findings in a rat maternal care paradigm highlight the complex and dynamic relation between early experiences and a variety of outcomes. In this review we propose adaptive hypotheses for …


Same-Sex Social Behavior In Meadow Voles: Multiple And Rapid Formation Of Attachments, Annaliese K. Beery, David M. Routman, Irving Zucker Apr 2009

Same-Sex Social Behavior In Meadow Voles: Multiple And Rapid Formation Of Attachments, Annaliese K. Beery, David M. Routman, Irving Zucker

Neuroscience: Faculty Publications

Adult meadow voles (Microtus pennsylvanicus) are solitary in the spring–summer reproductive season, but during winter months, females and males are socially tolerant and aggregate in groups. This behavioral difference is triggered by day length: female meadow voles housed in short, winterlike day lengths form same-sex partner preferences, whereas those housed in long, summer-like day lengths are less social. The present study demonstrates that same-sex social attachments in short day lengths are not exclusive; females formed concurrent attachments with more than one individual, and with non-kin as well as siblings. Partner preferences between females were established within one day of cohousing …


Maternal Photoperiodic History Affects Offspring Development In Syrian Hamsters, Annaliese K. Beery, Matthew J. Paul, Irving Zucker Oct 2008

Maternal Photoperiodic History Affects Offspring Development In Syrian Hamsters, Annaliese K. Beery, Matthew J. Paul, Irving Zucker

Neuroscience: Faculty Publications

During the first 7 weeks of postnatal life, short day lengths inhibit the onset of puberty in many photoperiodic rodents, but not in Syrian hamsters. In this species, timing of puberty and fecundity are independent of the early postnatal photoperiod. Gestational day length affects postnatal reproductive development in several rodents; its role in Syrian hamsters has not been assessed. We tested the hypothesis that cumulative effects of pre- and postnatal short day lengths would restrain gonadal development in male Syrian hamsters. Males with prenatal short day exposure were generated by dams transferred to short day lengths 6 weeks, 3 weeks, …


Day Length And Estradiol Affect Same-Sex Affiliative Behavior In The Female Meadow Vole, Annaliese K. Beery, Theresa J. Loo, Irving Zucker Jun 2008

Day Length And Estradiol Affect Same-Sex Affiliative Behavior In The Female Meadow Vole, Annaliese K. Beery, Theresa J. Loo, Irving Zucker

Neuroscience: Faculty Publications

Non-sexual social bonding between adult mammals remains poorly understood, despite its importance in many species. Female meadow voles are territorial and nest alone in long summer day lengths when circulating estradiol concentrations are high, but cohabit in groups in short winter photoperiods when estradiol secretion is low. The influence of day length and estradiol on same-sex huddling behavior was assessed in adult female pairs housed together in long day lengths (LDs) or short day lengths (SDs) from weaning. The behavior of intact, ovariectomized, and estradiol-treated ovariectomized females from each photoperiod was assessed during 3 hour partner preference tests. Intact SD …


Sex Differences In The Onset Of Seasonal Reproductive Quiescence In Hamsters, Annaliese K. Beery, Justin J. Trumbull, Jyeming M. Tsao, Ruth M. Costantini, Irving Zucker Jan 2007

Sex Differences In The Onset Of Seasonal Reproductive Quiescence In Hamsters, Annaliese K. Beery, Justin J. Trumbull, Jyeming M. Tsao, Ruth M. Costantini, Irving Zucker

Neuroscience: Faculty Publications

Day length is the primary cue used by many mammals to restrict reproduction to favourable spring and summer months, but it is unknown for any mammal whether the seasonal loss of fertility begins at the same time and occurs at the same rate in females and males; nor it established whether the termination of mating behaviour in males and females coincides with the loss of fertility. We speculated that females, owing to their greater energetic investment in reproduction, are the limiting sex in terminating offspring production in short days (SDs). Oestrous cycles and production of young were monitored in Syrian …
