The abnormal open-field behavior of SART-stressed rats and effects of some drugs on it.
As part of an investigation on the behavioral characteristics of SART-stressed animals, an animal model of autonomic imbalance, the open-field behavior of SART-stressed (repeated cold-stressed) rats was studied and compared with that of rats exposed to other types of stress. In addition, the effects of several drugs on it were also studied. As compared with normal rats, SART-stressed rats exhib...
متن کاملSubsensitivity to substance P in SART-stressed mice.
The sensitivity of SART-stressed (repeated cold-stressed) mice to substance P (SP) was studied. The behavioral responses to intrathecal SP in the stressed mice were less marked than those in non-stressed mice. The 50% effective dose of SP, however, did not differ between the 2 groups. Also, the antagonistic effect of intrathecal [D-Pro2, D-Trp7,9]-substance P against SP was not different. These...
متن کاملEffects of acute intra-hippocompal injection of bupropion on active avoidance learning in rats
Introduction: Learning and memory deficits in some diseases are new subjects of research. Bupropion, as dopamine and noradrenaline reuptake inhibitor and an antidepressant agent, has been previously shown to affect learning and memory processes. This study was designed to test the effect of intra-hippocompal bupropion injection on active avoidance learning task in rats. Methods: Adult male ...
متن کاملBasal Ganglia Output Controls Active Avoidance Behavior.
Engrained avoidance behavior is highly adaptive when it keeps away harmful events and can be highly maladaptive when individuals elude harmless situations in anxiety disorders, but the neural circuits that mediate avoidance are poorly understood. Using DREADDs and optogenetics in mice, we show that the output of the basal ganglia through the substantia nigra pars reticulata (SNr) controls activ...
متن کاملEffects of AF-DX116 and other muscarinic receptor antagonists on orthostatic hypotension in autonomic imbalanced (SART-stressed) rats.
SART (specific alternation of rhythm in temperature)-stressed rats are an animal model of autonomic imbalance created by exposing animals to repeated cold stress. The SART-stressed rats have been shown to easily develop orthostatic hypotension (OH). In this study, effects of AF-DX116, a selective M(2) antagonist, and other muscarinic receptor antagonists on OH were investigated in SART-stressed...
