Abstract:
Paralimbic association area in the temporal pole is situated between sensory association areas and the limbic regions and has direct connections with these areas and the ventral striatum. Corticostriatal connections of paralimbic association area in the temporal pole were studied with particular emphasis on specific projections of the ventral striatum to identify different contributions to the functional outcome of the ventral striatum. Retrograde tracers were injected into the five different regions of the ventral striatum such as the ventromedial caudate nucleus, ventral shell, central shell, dorsal core of the nucleus accumbens (NA), and ventrolateral putamen to identify the labeled cells of origin. Present results indicate that the temporal pole has specifically dense projections to the ventral shell of NA. This differential pattern of corticostriatal connectivity suggests that ventral shell region of ventral striatum is preferentially involved in the convergence of sensory and limbic stimulus to motivational and emotional states.
