Traumatic Stress Disorder Observed in an Adult Wild Captive Wolf (Canis lupus)
Tenino was an adult female wolf, born in the wild and placed into captivity at 1 year of age because of her participation in livestock depredation. Her method of capture, well documented, involved being darted twice by helicopter and translocated twice. This method of capture would have exposed her to the 2 factors that are […]
Neural plasticity, neuropeptides and anxiety in animals — implications for understanding and treating affective disorder following traumatic stress in humans
Exposure of rats to cats (predator stress) lastingly increases rodent anxiety-like behavior (ALB) in the elevated plus-maze. Previous work shows that lasting changes in ALB following predator stress depend on NMDA and CCKB receptors. In this paper we describe the effects of differing degrees of predator exposure on behavior. Effects depend on the behavioral measure. […]
Sexual motivation and anxiety-like behaviors of male rats after exposure to a trauma followed by situational reminders
Experiencing a traumatic event can produce long-lasting impairments in affective and social behaviors. In humans, psychopathologies associated with exposure to a single traumatic event often are associated with varying degrees of sexual dysfunction. Similarly, in rats, exposure to a trauma results in long-lasting changes in social behaviors. The current investigation examined if the sexual and […]
Mood and anxiety disorders in chimpanzees (pan troglodytes): A response to Rosati et al. (2012)
Assessing the psychological health of nonhuman primates living in captivity is essential, since many experiments and behavioral observations involve captive animals. This area is a research priority because it has ethical consequences, in addition to its applications for understanding human and nonhuman primate behavior. In 2011, we published our international study’s findings that chimpanzees with […]
