The use of conditioned defensive burying to test the effects of pimozide on associative learning.
Rats shocked by a wire-wrapped prod mounted on the wall of the experimental chamber buried the prod with available bedding material when they were tested 24 hr later. Injection of the neuroleptic, pimozide (1.0 mg/kg) before conditioning and again before testing disrupted this conditioned defensive burying; however, a concomitant reduction in general activity suggested that this deficit in cond...
متن کاملDefensive burying in rodents: ethology, neurobiology and psychopharmacology.
Defensive burying refers to the typical rodent behavior of displacing bedding material with vigorous treading-like movements of their forepaws and shoveling movements of their heads directed towards a variety of noxious stimuli that pose a near and immediate threat, such as a wall-mounted electrified shock-prod. Since its introduction 25 years ago by Pinel and Treit [J. Comp. Physiol. Psychol. ...
متن کاملEffects of β-Estradiol on Enhanced Conditioned Fear Induced by Single Prolonged Stress and Shock in Rats
Introduction:This study examined the effects of administration of subcutaneous β-estradiol on PTSD-like symptoms (the enhanced conditioned fear response, CFR) that induced by a single-prolonged stress (SPS) and shock in rats. Adult male Wistar rats were exposed to SPS procedure: restraint for 2 h, forced swim for 20 min, and ether anesthesia. Then the rats were placed in fear conditioning syste...
متن کاملThe digestive and defensive basis of carcass utilization by the burying beetle and its microbiota
Insects that use ephemeral resources must rapidly digest nutrients and simultaneously protect them from competitors. Here we use burying beetles (Nicrophorus vespilloides), which feed their offspring on vertebrate carrion, to investigate the digestive and defensive basis of carrion utilization. We characterize gene expression and microbiota composition in the gut, anal secretions, and on carcas...
