A growing body of evidence indicates that repeated exposure to cocaine leads to profound changes in glutamate transmission in limbic nuclei, particularly the nucleus accumbens. This review focuses on preclinical studies of cocaine-induced behavioral

Cumulative evidence in rats suggests that the pontine parabrachial nuclei (PBN) are necessary for assigning hedonic value to taste stimuli. In a series of studies, our laboratory has investigated the parabrachial coding of sapid sucrose in normal and

Recent studies have demonstrated the existence of receptors for L-glutamate (GLU) and their transduction molecules in the gut mucosa as well as in the oral cavity. Among 20 amino acids, gastric vagal afferent fibers respond only to intragastric admin

Ethyl alcohol (EtOH), the main psychoactive ingredient of alcoholic drinks, is widely considered responsible for alcohol abuse and alcoholism through its positive motivational properties, which depend, at least partially, on the activation of the mes

Morphine withdrawal produces a hypofunction of mesencephalic dopamine (DA) neurons which impinge upon medium spiny neurons (MSN) of the forebrain. After chronic treatment rats were either spontaneously or pharmacologically withdrawn from chronic morp

An individual's drug abuse pattern is determined by a multitude of factors. Among these, simple pharmacological determinants of within-binge drug consumption are sorely underinvestigated. We therefore determined if within-session operant responsing t

Cocaine abuse is a significant problem not only in the general population but also among pregnant women. Since cocaine readily crosses the placenta and is metabolized slowly in fetuses, they can be exposed to significant levels of cocaine for long pe

The repeated use of psychostimulants in humans has been associated with progressive enhancement of anxiety, panic attacks, and eventually paranoid psychosis. The appearance of such behaviors has been termed behavioral sensitization, which forms part

The nitric oxide (NO)/cGMP pathway triggers key events in synaptic phenomena involved in learning and memory. Using in situ hybridization, the present report demonstrates that NO released by sodium nitroprusside regulates egr-1, c-fos, and junB immed

Neonatal exposure to moderate doses of methamphetamine during the first month of life in the rat affects tyrosine hydroxylase gene expression in the substantia nigra and nigrostriatal tyrosine hydroxylase activity. The main goal of this work was to e
