Stress hormones released in the CNS following exposure to unavoidable, aversive stimuli have been shown to alter the physiology of neurons in multiple brain regions including hippocampus, amygdala, prefrontal cortex, and ventral tegmental area. The nucleus accumbens (NAc), a motor-limbic interface linked to motivation and reward, receives inputs from each of these stress-affected brain regions,...
We discover a new contribution to the pressure (or stress) exerted by a suspension of self-propelled bodies. Through their self-motion, all active matter systems generate a unique swim pressure that is entirely athermal in origin. The origin of the swim pressure is based upon the notion that an active body would swim away in space unless confined by boundaries-this confinement pressure is preci...
AIMS Preclinical and clinical data suggest an involvement of atrial natriuretic peptides (ANP) in alcohol-associated psychopathology. We now present first data on alcohol drinking behaviour in mice lacking a functional natriuretic peptide-A (NPR-A) receptor. METHODS NPR-A(-/-) and wild-type mice were given a free choice between water and increasing concentrations of alcohol (2-16%). A forced ...
Objective: A question raised here as to whether exercise training combined with Mg supplementation could improve the symptoms of neuropathic pain such as the thermal hyperalgesia more effectively than either of the two alone. This study aimed to investigate the combined effect of swim training and Mg supplementation on thermal hyperalgesia in streptozotocin (STZ) induced diabetic rats. Materia...
The forced swim test (FST), originally developed by Porsolt et al., is highly valuable for assessing the antidepressant-like effects of the majority of currently-available antidepressants. Lucki et al. modified some parameters of the traditional FST in order to facilitate the differentiation between serotonergic and noradrenergic classes of antidepressant drugs. In addition, the FST is one of t...
INTRODUCTION The formalin test is the most accepted chemical test for evaluation of nociception. It requires the injection of an adequate amount of formalin into the surface of the hindpaw. Formalin test consists of phase 1 (0-7 min) and phase 2 (15-60) in which the animal shows painful behaviors. These phases are separated with a quiet phase named interphase, in which the nociceptive responses...
