In a recent study we found that when rats sham fed 6% sucrose, 10% sucrose, and 100% corn oil, the rank order of inhibitory potency for D-1 and D-2 receptor antagonists was 6% sucrose greater than 10% sucrose greater than 100% corn oil. In a complementary study, sham-feeding rats preferred 100% corn

Both real and sham feeding of sucrose increase dopamine (DA) overflow in the nucleus accumbens (NAc). Fat is another constituent of foods that is inherently preferred by humans and rodents. We examined the affect of sham feeding corn oil in rats that were food and water deprived overnight. Rats were
High fructose corn syrup induces metabolic dysregulation and altered dopamine signaling in the absence of obesity.

The contribution of high fructose corn syrup (HFCS) to metabolic disorder and obesity, independent of high fat, energy-rich diets, is controversial. While high-fat diets are widely accepted as a rodent model of diet-induced obesity (DIO) and metabolic disorder, the value of HFCS alone as a rodent

Patients undergoing methadone maintenance treatment self-report enhanced preferences for, and excessive consumption of, foods rich in sugar. However, it is unclear whether these are direct pharmacological effects of methadone or the consequences of metabolic dysfunctions induced by addiction to

Sugars and fats elicit innate and learned flavor preferences with the latter mediated by flavor-flavor (orosensory) and flavor-nutrient (post-ingestive) processes. Systemic dopamine (DA) D1 (SCH23390: SCH) and D2 (raclopride: RAC), but not opioid antagonists blocked the acquisition and expression of

This study uses cellular c-fos activation to assess effects of novel ingestion of fat and sugar on brain dopamine (DA) pathways in rats. Intakes of sugars and fats are mediated by their innate attractions as well as learned preferences. Brain dopamine, especially meso-limbic and meso-cortical

Changes in the extracellular concentration of dopamine (DA) in the nucleus accumbens (NAc) shell and the basolateral amygdala (BLA) resulting from the voluntary ingestion of either corn oil, mineral oil, or 1% linoleic acid diluted with mineral oil as a vehicle were measured in rats by using in vivo

Polychlorinated biphenyls (PCBs) are recognized as persistent environmental pollutants that may cause adverse health problems. Despite extensive investigations of PCB in neural function, little is known about behavioral traits by PCB exposure and its neurochemical mechanism. Here, we report the

OBJECTIVE
To investigate the effects of pyrethroids on nigrostriatal dopaminergic pathways in male rats and its mechanism.
METHODS
Different doses of permethrin (PM, 200, 400 mg/kg) and deltamethrin (DM, 6.25, 12.50 mg/kg) in corn oil were administered to rats by gavage once daily for ten days, then

Animals learn to prefer flavors associated with the intake of sugar (sucrose, fructose, glucose) and fat (corn oil: CO) solutions. Conditioned flavor preferences (CFP) have been elicited for sugars based on orosensory (flavor-flavor: e.g., fructose-CFP) and post-ingestive (flavor-nutrient: e.g.,

Pregnant CD-1 mice were given 32 mg/kg of 3,4,3',4'-tetrachlorobiphenyl (TCB) or corn oil vehicle, by gavage, on days 10--16 of gestation. At 1 year of age, the offspring were tested for spontaneous motor activity; the mice were then killed and dopamine (DA) levels and specific DA receptor binding

Overconsumption of nutrients high in fats and sugars can lead to obesity. Previous studies indicate that sugar or fat consumption activate individual brain sites using Fos-like immunoreactivity (FLI). Sugars and fats also elicit conditioned flavor preferences (CFP) that are differentially mediated

Mice show a strong preference for corn oil, which was thought to be elicited by stimulation in the oral cavity. Grooming behavior is known to be induced by dopamine D(1) stimulation in rodents. Therefore, we evaluated stimulation by corn oil in the oral cavity and the contribution of D(1) receptors
