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 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...
متن کاملBehavioural responses to elevated plus-maze and defensive burying testing: effects on subsequent ethanol intake and effect of ethanol on retention of the burying response.
Based upon repeated observations of a relationship between defensive burying (DB), ethanol intake and stress ulcer susceptibility, and recurring questions regarding what DB behaviour reflects, two experiments were performed. Experiment 1 showed that prod shock exposure per se reduced subsequent ethanol intake, as did access to burying material. In rats without burying material in the conditioni...
متن کاملMaternal behavior modulates X-linked inheritance of behavioral coping in the defensive burying test.
BACKGROUND Complex behavioral traits such as coping strategies in response to stress are usually formed by genetic and environmental influences. METHODS By exploiting the phenotypic and genotypic differences between the Wistar Kyoto (WKY) and Fischer 344 (F344) inbred rat strains, we recently identified three X chromosome-linked quantitative trait loci contributing to differences in coping st...
