Reliability of high and low anxiety-related behaviour: influence of laboratory environment and multifactorial analysis (2002)

Salome, N, Viltart, O, Darnaudery, M, Salchner, P, Singewald, N, Landgraf, R, ...

The reliability of behavioural data constitutes a major concern in the neuroscience field. Indeed, discrepancies in the behavioural patterns of mice or rats in the same anxiety tests performed in...

Vasopressin in CSF and plasma in depressed suicide attempters: preliminary results (2002)

Brunner, J, Keck, ME, Landgraf, R, Uhr, M, Namendorf, C, Bronisch, T

Increased plasma arginine vasopressin (AVP) concentrations have been reported in depressed suicide attempters. Plasma AVP is primarily produced by the magnocellular system in response to increased...

High vs low anxiety-related behavior rats: An animal model of extremes in trait anxiety (2002)

Landgraf, R, Wigger, A

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 susceptible...

Vasopressin from hypothalamic magnocellular neurons has opposite actions at the adenohypophysis and in the supraoptic nucleus on ACTH secretion (2002)

Wotjak, CT, Ludwig, M, Ebner, K, Russell, JA, Singewald, N, Landgraf, R, ...

Magnocellular vasopressinergic and oxytocinergic neurons of the hypothalamic supraoptic (SON) and paraventricular nuclei comprise the hypothalamic-neurohypophysial system, which is crucially involved...

The CRH1 receptor antagonist R121919 attenuates stress-elicited sleep disturbances in rats, particularly in those with high innate anxiety (2002)

Lancel, M, Müller-Preuß, P, Wigger, A, Landgraf, R, Holsboer, F

Excessive corticotropin-releasing hormone (CRH) secretion in limbic and prefrontal brain areas has been postulated to underly stress-related clinical conditions. Studies in mice with deleted or...

Serotonin in brain regions of rats differing in their inborn locomotor activity (2002)

Umriukhin, AE, Landgraf, R

Serotonin contents in the paraventricular hypothalamic nucleus (PVN) and dorsal hippocampis of rats with different levels of inborn motor activity were studied by microdialysis in basal and...

Intracellular calcium stores regulate activity-dependent neuropeptide release from dendrites (2002)

Ludwig, M, Sabatier, N, Bull, PM, Landgraf, R, Dayanithi, G, Leng, G

Information in neurons flows from synapses, through the dendrites and cell body (soma), and, finally, along the axon as spikes of electrical activity that will ultimately release neurotransmitters...

Alcohol self-administration in two rat lines selectively bred for extremes in anxiety-related behavior (2002)

Henniger, MSH, Spanagel, R, Wigger, A, Landgraf, R, Hölter, SM

According to the tension reduction hypothesis, individuals with art elevated anxiety level may be more sensitive to the anxiolytic effects of alcohol and may, therefore, have a higher predisposition...

Cognitive performance in rats differing in their inborn anxiety (2002)

Ohl, F, Roedel, A, Storch, C, Holsboer, F, Landgraf, R

There is profound evidence that cognitive processes and anxiety are interrelated, To team more about this interaction. the authors tested rats bred for either high (HABs) or low (LABs)...

Forced swimming triggers vasopressin release within the amygdala to modulate stress-coping strategies in rats (2002)

Ebner, K, Wotjak, CT, Landgraf, R, Engelmann, M

Previously, we have demonstrated that forced swimming triggers the release of arginine vasopressin (AVP) within the septum of rats, where AVP modulates stress-coping strategies. The present study was...

Vasopressin mediates the response of the combined dexamethasone/CRH test in hyper-anxious rats: Implications for pathogenesis of affective disorders (2002)

Keck, ME, Wigger, A, Welt, T, Müller, MB, Gesing, A, Reul, JMHM, ...

To investigate the neuroendocrine alterations linked to inborn emotionality in two Wistar rat lines selectively bred for either high (HAB) or low (LAB) anxiety-related behavior, we administered the...
