Effects of estrus cycle stage on defensive behavior in female Long-Evans hooded rats

Autor: Robert J. Blanchard, Yoav Litvin, Nathan S. Pentkowski, D. Caroline Blanchard

Publikováno v: Physiologybehavior. 194

This study investigated the influence of the estrus cycle in mediating cat odor-induced unconditioned and conditioned defensive behaviors in female Long-Evans hooded rats. Unconditioned defensive behaviors were assessed during predatory cue exposure;

Estradiol regulates responsiveness of the dorsal premammillary nucleus of the hypothalamus and affects fear- and anxiety-like behaviors in female rats

Autor: Giuseppe Cataldo, Donald W. Pfaff, Yoav Litvin, Lee Ming Kow

Publikováno v: European Journal of Neuroscience. 40:2344-2351

Research suggests a causal link between estrogens and mood. Here, we began by examining the effects of estradiol (E2 ) on rat innate and conditioned defensive behaviors in response to cat odor. Second, we utilized whole-cell patch clamp electrophysio

Fibroblast growth factor 2 alters the oxytocin receptor in a developmental model of anxiety-like behavior in male rat pups

Autor: Mariel B. Ríos, Bruce S. McEwen, Sraboni Chaudhury, Peter Blandino, Yoav Litvin, Pamela M. Maras, Miriam E. R. Baker, Huda Akil, Cortney A. Turner, Stanley J. Watson

We aimed to determine the short-term effects of early-life stress in the form of maternal separation (MS) on anxiety-like behavior in male rat pups. In order to assess anxiety, we measured 40 kHz separation-induced ultrasonic vocalizations (USV) on p

Persistent Increase in Hypothalamic Arginine Vasopressin Gene Expression During Protracted Withdrawal from Chronic Escalating-Dose Cocaine in Rodents

Autor: Yan Zhou, Anna Paola Piras, Mary Jeanne Kreek, Donald W. Pfaff, Yoav Litvin

Publikováno v: Neuropsychopharmacology. 36:2062-2075

Arginine vasopressin (AVP) from the paraventricular nucleus (PVN) of hypothalamus has important roles in regulation of the hypothalamic-pituitary-adrenal (HPA) axis and stress-related behaviors during chronic stress. It is unknown, however, whether A

Maternal separation modulates short-term behavioral and physiological indices of the stress response

Autor: Philip Tovote, D. Caroline Blanchard, Thomas Zeyda, Lanikea B. King, Amy Vasconcellos, Robert J. Blanchard, Christopher Dunlap, Yoav Litvin, Joachim Spiess, Nathan S. Pentkowski

Publikováno v: Hormones and Behavior. 58:241-249

Early-life stress produces an anxiogenic profile in adulthood, presumably by activating the otherwise quiescent hypothalamic-pituitary-adrenal (HPA) axis during the vulnerable 'stress hyporesponsive period'. While the long-term effects of such early-

Rat 22kHz ultrasonic vocalizations as alarm cries

Autor: D. Caroline Blanchard, Robert J. Blanchard, Yoav Litvin

Publikováno v: Behavioural Brain Research. 182:166-172

Rats incorporate circa 22kHz ultrasonic alarm cries into their defense pattern in response to a predator threat. These calls are dependent on conspecific presence, show gender differences, and tend to be emitted from a place of relative safety. Rats

CRF type 1 receptors in the dorsal periaqueductal gray modulate anxiety-induced defensive behaviors

Autor: Robert J. Blanchard, Nathan S. Pentkowski, D. Caroline Blanchard, Yoav Litvin

Publikováno v: Hormones and Behavior. 52:244-251

The dorsal periaqueductal gray (dPAG) is involved in defensive coping reactions to threatening stimuli. Corticotropin releasing factor (CRF) is substantially implicated as a direct modulator of physiological, endocrine and behavioral responses to a s

Effects of intra-PAG infusion of ovine CRF on defensive behaviors in Swiss-Webster mice

Autor: Ricardo Luiz Nunes-de-Souza, D. Caroline Blanchard, Robert J. Blanchard, Yoav Litvin, Eduardo F. Carvalho-Netto

Publikováno v: Behavioural Brain Research. 176:222-229

The midbrain dorsal periaqueductal gray (DPAG) is part of the brain defensive system involved in active defense reactions to threatening stimuli. Corticotrophin releasing factor (CRF) is a peptidergic neurotransmitter that has been strongly implicate
