Spatio-temporal integration in the substrate for self-stimulation of the prefrontal cortex.

abstract：:Previous researchers have assumed that malaise-inducing drugs condition aversions to tastes more readily than to textural stimuli. The present report shows that rats given a single injection of lithium chloride after they have sampled a viscous fluid, subsequently showed greater avoidance of that fluid than did contro...

abstract：:The medial zone of parabrachial nuclei (PBN) serves as an obligatory synapse in the central gustatory system in rodents. Lesions in the PBN impair taste aversion learning and depletion-induced sodium appetite in rats, and also alter the ingestion of sapid stimuli. Interpretation of these lesion-induced behavioral defi...
