Repeated exposure of male mice to low doses of lipopolysaccharide: Dose and time dependent development of behavioral sensitization and tolerance in an automated light–dark anxiety test
Although lipopolysaccharide (LPS) is widely used to examine immune behavior relationships there has been little consideration of the effects of low doses and the roles of sensitization and, orExpand

Inhibition of LiCl-induced conditioning of anticipatory nausea in rats following immune system stimulation: Comparing the immunogens lipopolysaccharide, muramyl dipeptide, and polyinosinic:
The effects of the bacterial endotoxins, lipopolysaccharide (LPS) and muramyl dipeptide (MDP; Experiment 1), and the viral mimetic, polyinosinic: polycytidylic acid (poly I:C; Experiment 2), on theExpand

Pathogen threat and unfamiliar males rapidly bias the social responses of female mice
There is mounting evidence that pathogen threat affects social preferences and responses. In humans, the presence of strangers also elicits heightened sensitivity to pathogen threat, promotingExpand

Simultaneous conditioning of “gaping” responses and taste avoidance in rats injected with LiCl and saccharin: Examining the role of context and taste cues in the rodent model of anticipatory nausea
This study examined whether rats can simultaneously learn to associate lithium chloride (LiCl)-induced nausea with both contextual and intravascular taste cues. During the conditioning phase (4 days,Expand

Acute corticosterone increases conditioned spontaneous orofacial behaviors but fails to influence dose related LiCl-induced conditioned "gaping" responses in a rodent model of anticipatory nausea.
Acute administration of corticosterone has been shown to facilitate learning in a number of associative paradigms, including LiCl-induced conditioned taste aversion learning. The present studyExpand

Lipopolysaccharide inhibits the simultaneous establishment of LiCl-induced anticipatory nausea and intravascularly conditioned taste avoidance in the rat
This study examined the effects of the bacterial endotoxin, lipopolysaccharide (LPS), on the establishment of anticipatory nausea and conditioned taste avoidance in a simultaneous conditioningExpand

Rodent sex differences in disgust behaviors (anticipatory nausea) conditioned to a context associated with the effects of the toxin LiCl: Inhibition of conditioning following immune stimulation with
ABSTRACT This study examined sex differences in the establishment of lithium chloride (LiCl)‐induced conditioned disgust behavior (anticipatory nausea) to a distinct context in adult male and femaleExpand

Lipopolysaccharide (LPS) induced sickness in adolescent female rats alters the acute-phase response and lithium chloride (LiCl)- induced impairment of conditioned place avoidance/aversion learning,
ABSTRACT The multi‐variable locomotor activity effects of LiCl treatment in female rats were examined in a conditioned place avoidance/aversion (CPA) paradigm. In addition, the sickness effects of anExpand

Oxytocin, social factors, and the expression of conditioned disgust (anticipatory nausea) in male rats
Disgust has been proposed to have evolved as a means to rid the body and mouth of noxious substances and toxins, as well as to motivate and facilitate avoidance of contact with disease-causingExpand

Conditioned disgust in rats (anticipatory nausea) to a context paired with the effects of the toxin LiCl: Influence of sex and the estrous cycle
ABSTRACT The role of sex and estrous phase in the conditioning of toxin‐induced disgust reactions (anticipatory nausea) to a novel context were examined in adult rats. Conditioned oral gapingExpand
