A collection of 125 PHAL experiments in the rat has been analyzed to characterize the organization of projections from each amygdalar cell group (except the nucleus of the lateral olfactory tract) to the bed nuclei of the stria terminalis, which surround the crossing of the anterior commissure. The results suggest three organizing principles of these(More)
'Amygdala' and 'amygdalar complex' are terms that now refer to a highly differentiated region near the temporal pole of the mammalian cerebral hemisphere. Cell groups within it appear to be differentiated parts of the traditional cortex, the claustrum, or the striatum, and these parts belong to four obvious functional systems--accessory olfactory, main(More)
The organization of axonal projections from the basomedial nucleus of the amygdala (BMA) was examined with the Phaseolus vulgaris leucoagglutinin (PHAL) method in adult male rats. The anterior and posterior parts of the BMA, recognized on cytoarchitectonic grounds, display very different projection patterns. Within the amygdala, the anterior basomedial(More)
The organization of axonal projections from the oval and fusiform nuclei of the bed nuclei of the stria terminalis (BST) was characterized with the Phaseolus vulgaris-leucoagglutinin (PHAL) anterograde tracing method in adult male rats. Within the BST, the oval nucleus (BSTov) projects very densely to the fusiform nucleus (BSTfu) and also innervates the(More)
The expression of innate reproductive, defensive, and ingestive behaviors appears to be controlled by three sets of medial hypothalamic nuclei, which are modulated by cognitive influences from the cerebral hemispheres, including especially the amygdala and hippocampal formation. PHAL analysis of the rat amygdala indicates that a majority of its cell groups(More)
The lateral part of the central nucleus projects densely to only three regions: the medial part of the central nucleus, restricted parts of the bed nuclei of the stria terminalis, and the parabrachial nucleus in the pons. The possible role of the lateral central amygdalar nucleus in circuitry mediating conditioned emotional responses is discussed; changing(More)
Experimental animals that are trained to associate a cue with food consumption when hunger prevails will subsequently consume a greater amount of food when that cue is presented under conditions of satiety. Previously, we showed that this phenomenon of conditioned potentiation of feeding is abolished by a neurotoxic lesion that encompasses the basolateral(More)
Motivation plays an important role in the control of food intake. This review will focus on recent findings using a neural systems analysis of a behavioral model for learned motivational control of eating. In this model, environmental cues that acquire motivational properties through Pavlovian conditioning can subsequently override satiety and promote(More)
Both control rats and rats with neurotoxic lesions of the amygdala central nucleus ate more food during presentations of a conditioned stimulus (CS) previously paired with food than during an unpaired CS. This potentiation occurred regardless of whether the food was presented in its usual place or in a different location. By contrast, rats with neurotoxic(More)
The axonal projections of the juxtacapsular nucleus of the anterior division of the bed nuclei of the stria terminalis (BSTju) were examined with the Phaseolus vulgaris-leucoagglutinin (PHAL) method in the adult male rat. Our results indicate that the BSTju displays a relatively simple projection pattern. First, it densely innervates the medial central(More)
