Defensive 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 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 کاملAlias burying: Unique variables without destructive reads
An unshared object can be accessed without regard to possible conflicts with other parts of a system, whether concurrent or single-threaded. A unique variable (sometimes known as a ‘free’ or ‘linear’ variable) is one that either is null or else refers to an unshared object. Being able to declare and check which variables are unique improves a programmer’s ability to avoid program faults. In pre...
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...
متن کاملCentral administration of ghrelin induces conditioned avoidance in rodents
Feelings of hunger carry a negative-valence (emotion) signal that appears to be conveyed through agouti-related peptide (AgRP) neurons in the hypothalamic arcuate nucleus. The circulating hunger hormone, ghrelin, activates these neurons although it remains unclear whether it also carries a negative-valence signal. Given that ghrelin also activates pathways in the midbrain that are important for...
