High vs low anxiety-related behavior rats: an animal model of extremes in trait anxiety

R Landgraf, A Wigger - Behavior genetics, 2002 - Springer
In addition to their robust difference in trait anxiety, as illustrated by a variety of behavioral
tests, HAB and LAB rats differ in their stress coping strategies, the former being more …

Born to be anxious: neuroendocrine and genetic correlates of trait anxiety in HAB rats

R Landgraf, A Wigger - Stress, 2003 - Taylor & Francis
This review summarises behavioural, neuroendocrine, and genetic characteristics of Wistar
rats bred for either high (HAB) or low (LAB) anxiety-related behaviour. Compared to LABs, …

Brain oxytocin inhibits basal and stress‐induced activity of the hypothalamo‐pituitary‐adrenal axis in male and female rats: partial action within the paraventricular …

Neumann, A Wigger, Torner, Holsboer… - Journal of …, 2000 - Wiley Online Library
Oxytocin is a classic reproductive neuropeptide in the female mammal, but its functions in

Brain oxytocin: differential inhibition of neuroendocrine stress responses and anxiety-related behaviour in virgin, pregnant and lactating rats

ID Neumann, L Torner, A Wigger - Neuroscience, 1999 - Elsevier
The involvement of brain oxytocin in the attenuated responsiveness of the hypothalamo-pituitary–adrenal

Periodic maternal deprivation induces gender-dependent alterations in behavioral and neuroendocrine responses to emotional stress in adult rats

A Wigger, ID Neumann - Physiology & behavior, 1999 - Elsevier
There is evidence that stressful events during the neonatal “stress hyporesponsive period”
may influence both emotional behavior and the maturation of the hypothalamic–pituitary–…

A Wigger, MM Sánchez, KC Mathys, K Ebner… - …, 2004 - nature.com
To model aspects of trait anxiety/depression, Wistar rats were bred for extremes in either
hyper (HAB)-or hypo (LAB)-anxiety as measured on the elevated plus-maze and in a variety of …

Attenuation of hypothalamic‐pituitary‐adrenal axis stress responses in late pregnancy: changes in feedforward and feedback mechanisms

HA Johnstone, A Wigger, AJ Douglas… - Journal of …, 2000 - Wiley Online Library
The hypothalamic‐pituitary‐adrenal axis is hyporesponsive to stress in late pregnancy,
exemplified as reduced adrenocorticotropic hormone (ACTH) and corticosterone responses to …
