    An experimental study of the ventral striatum of the golden hamster. I. Neuronal connections of the nucleus accumbens

    As part of an experimental study of the ventral striatum, the horseradish peroxidase (HRP) method was used to examine the afferent and efferent neuronal connections of the nucleus accumbens. Following iontophoretic applications or hydraulic injections of HRP in nucleus accumbens, cells labeled by retrograde transport of HRP were observed in the ipsilateral telencephalon in the posterior agranular insular, perirhinal, entorhinal, and primary olfactory cortices, in the subiculum and hippocampal field CA1, and in the anterior and posterior divisions of the basolateral amygdaloid nucleus. In the diencephalon, labeled neurons were present ipsilaterally in the central medial, paracentral and parafascicular intralaminar nuclei, and in the midline nuclei parataenialis, paraventricularis, and reuniens. Retrograde labeling was observed in the ipsilateral brainstem in cells of the ventral tegmental area and dorsal raphe. Many of these projections to nucleus accumbens were found to be topographically organized. Anterograde transport of HRP from nucleus accumbens demonstrated ipsilateral terminal fields in the ventral pallidum and substantia nigra, pars reticulata. The afferent projections to nucleus accumbens from the posterior insular and perirhinal neocortices, intralaminar thalamus, and the dopamine-containing ventral tegmental area are analogous to the connections of the caudatoputamen, as are the efferents from nucleus accumbens to the substantia nigra and ventral globus pallidus. These connections substantiate the classification of nucleus accumbens as a striatal structure and provide support for the recently proposed concept of the ventral striatum. Furthermore, the demonstration that a number of limbic system structures, including the amygdala, hippocampal formation, entorhinal cortex, and olfactory cortex are important sources of afferents to the nucleus accumbens, suggests that the ventral striatum may serve to integrate limbic information into the striatal system.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/50009/1/901910203_ftp.pd

    The Brain and the Behavioral Sciences

    The increasing visibility and sense of intellectual opportunity associated with neuroscience in recent years have in turn stimulated a growing interest in its past. For the first time, a general reference book on the history of science has seen fit to include a review of the history of the brain and behavioral sciences as a thread to be reckoned with within the broader narrative tapestry. On the one hand, this looks like a welcome sign that a new historical subfield has “come of age.” On the other hand, when one settles down to the task of composing a “state of the art” narrative, one realizes just how much these are still early days. The bulk of available secondary literature still swims in a space between nostalgic narratives of great men and moments, big “march of ideas” overviews, and an unsystematic patchwork of more theorized forays by professional historians into specific themes (e.g., phrenology, brain localization, reflex theory). The challenge of imagining a comprehensive narrative is made all the more formidable by the fact that we are dealing here with a history that resists any easy or clean containment within disciplinary confines. The paper trail of ideas, experiments, clinical innovations, institutional networks, and high-stakes social debates not only moves across obvious sites of activity such as neurology, neurosurgery, and neurophysiology but also traverses fields as (only apparently) distinct as medicine, evolution, social theory, psychology, asylum management, genetics, philosophy, linguistics, anthropology, computer science, and theology.History of Scienc
