The organization of projections from the cortes, amygdala, and hypothalamus to the nucleus of the solitary tract in rat
Direct projections from the forebrain to the nucleus of the solitary tract (NTS) and dorsal motor nucleus of the vagus in the rat medulla were mapped in detail using both retrograde axonal transportExpand

Serotonin mediates food-odor associative learning in the nematode Caenorhabditis elegans
We demonstrate that Caenorhabditis elegans is able to form an association between the presence of the odorant benzaldehyde and the food content of its environment. When exposed to 100% benzaldehydeExpand

The nucleus raphe dorsalis of the rat and its projection upon the caudatoputamen. A combined cytoarchitectonic, immunohistochemical and retrograde transport study.
The nucleus raphe dorsalis of the albino rat has been studied in the following three ways: (1) the cell mass was subjected to a detailed cytoarchitectonic analysis, based upon Nissl-stained material;Expand

Ventral Tegmental Area BDNF Induces an Opiate-Dependent–Like Reward State in Naïve Rats
BDNF and Drug Dependence Brain-derived neurotrophic factor (BDNF) is a growth factor involved in neuronal plasticity that is expressed after chronic administration of drugs of abuse and may play aExpand

Mutations that prevent associative learning in C. elegans.
The nematode Caenorhabditis elegans offers a promising system for the reductionist study of learning and memory. In this article, classical conditioning in C. elegans is demonstrated with a varietyExpand

Neurobiology of motivation: double dissociation of two motivational mechanisms mediating opiate reward in drug-naive versus drug-dependent animals.
Separate brain manipulations double dissociate two motivational mechanisms underlying the rewarding effects of opiates. Lesions of the brain stem tegmental pedunculopontine nucleus block theExpand

Lesions of the Tegmental Pedunculopontine Nucleus Block the Rewarding Effects and Reveal the Aversive Effects of Nicotine in the Ventral Tegmental Area
Nicotine, the primary psychoactive component of tobacco smoke, is known to possess potent rewarding and aversive stimulus properties. The mammalian ventral tegmental area (VTA) is involvedExpand

Insulin Signaling Plays a Dual Role in Caenorhabditis elegans Memory Acquisition and Memory Retrieval
Insulin signaling plays a prominent role in regulation of dauer formation and longevity in Caenorhabditis elegans. Here, we show that insulin signaling also is required in benzaldehyde–starvationExpand

Organization of the projections of a circumventricular organ: The area postrema in the rat
The projections of the rat area postrema were analysed using antero‐grade and retrograde axonal transport techniques. Discrete injections of wheat germ agglutinin conjugated to horseradish peroxidaseExpand

Mechanisms of striatal pattern formation: conservation of mammalian compartmentalization.
The striatum is composed of two neuroanatomically and neurochemically defined compartments, termed the patches and matrix. We compared this compartmentalization of the striatum in sections from theExpand
