The effect of alpha-melanotropin (alpha-MSH) on the rat mesolimbic dopaminergic activity was estimated by measuring the changes in dihydroxyphenyl acetic acid (DOPAC) and dopamine (DA) endogenous levels in the nucleus accumbens (Ac) and caudate putamen (CP). A marked increase of DOPAC/DA ratios resulting from an increase in DOPAC and decrease in DA levels(More)
Rats were injected with 1 ?g of alpha-melanocyte stimulating hormone (?-MSH) into the third ventricle and locally in the ventral tegmental area and in different regions of the substantia nigra. The modifications produced on grooming behavior and locomotion as well as on the dopamine content of the nucleus accumbens and the caudate putamen, were studied.(More)
This note summarizes some mathematical relations between the probability distributions for the states of a network of binary units and a subnetwork thereof, under an assumption of symmetry. These relations are standard results of probability theory, but seem to be rarely used in neuroscience. Some of their consequences for inferences between network and(More)
Male Sprague-Dawley rats were chronically treated with a liquid diet containing 6.5% (v/v) ethanol or equicaloric sucrose. Rats were killed after 21 days of treatment. alpha-MSH-like immunoreactivity was measured in the intermediate lobe of the pituitary gland and in several brain regions. Chronic ethanol treatment significantly reduced alpha-MSH-like(More)
Alpha-melanotropin (alpha-MSH) injected into the ventral tegmental area (VTA) or intraventricularly (icv) elicits excessive grooming. The icv infusion of the peptide also induces the stretching-yawning syndrome (SYS). The present study demonstrates that intra-peritoneal, icv or VTA administration of atropine, suppresses alpha-MSH-induced behavior elicited(More)
The uptake of tritiated dopamine [3H] (DMI insensitive DA uptake) by synaptosomal fractions isolated from rat mediobasal hypothalamus (MBH) and caudate putamen (CP) was measured in the presence of different concentrations of alpha-melanocyte stimulating hormone (alpha-MSH) and Pro-Leu-Gly-NH2 (PLG; MIF-1) which is an inhibitor of alpha-MSH release.
