TL;DR: Long-term infusion of glucose, beta-hydroxybutyrate, and glycerol into the third ventricle of the rat brain caused a stabilization of body weight at a lower than normal level, consistent with the view that the systems controlling food intake and body weight are sensitive to the availability of brain fuels.

TL;DR: In rats treated systemically with either amphetamine, amfonelic acid or apomorphine, large numbers of cells displaying Fos-like immunoreactivity (FLI) could be seen in the lateral zone of the lateral habenula, and these findings support the concept of a functional differentiation of the medial and lateral regions of theateral habenulas.

TL;DR: A68930, (1R,3S)-1-aminomethyl-5,6-dihydroxy-3-phenylisochroman HCl, is a potent (EC50 = 2.5 nM), partial (intrinsic activity = 66% of dopamine) agonist in the fish retina dopamine-sensitive adenylate cyclase model of the D1 dopamine receptor.

TL;DR: The results may suggest that rats do not self-administer ethanol for its intoxicating properties, and that the affective state produced by ethanol administration per se is not readily conditionable to environmental cues.

TL;DR: Electrolytic lesions of the median raphe nucleus were found to increase locomotion but decrease rearing in the open field, and these lesions eliminated the preference for entering a novel arm displayed by sham operated animals in a test of exploratory behavior.
