“…Prefrontal connections occupy the anterior half of the volume of the IC. Previous studies observed localization of the prefrontal connections in the ALIC (10–12); however, our observations highlight the large volume in the IC that is occupied by these tracts—an aspect of the structure that is not well appreciated in most neuroanatomy textbooks. This is because of the fact that our anatomical understanding of prefrontal connections originates from studies of these connections in nonhuman primates which have a much smaller prefrontal cortex than humans (12, 36).…”

“…Clinicopathological (4, 5) and postmortem investigations (6–8) supported this observation. Tracer studies in nonhuman primates showed that the ALIC is predominantly occupied by connections between the prefrontal (9–11) and temporal (12, 13) cortices and other cortical or subcortical structures. The PLIC includes connections of the parietal (14), temporal (12, 13), occipital (14, 15), and sensorimotor (16, 17) cortices.…”

Purpose: To exploit diffusion imaging tractography to produce a two-dimensional (xy) probabilistic population map of the cortical connections within the human internal capsule (IC). Materials and Methods:Diffusion tensor imaging (DTI) was carried out on 11 healthy volunteers. We parceled an axial section of the IC according to its connections to the prefrontal, premotor, primary motor, primary somatosensory, posterior parietal, and occipital cortices using our locally developed probabilistic algorithm.Results: A consistent topographical organization was generated that was consistent with our anatomical knowledge of the IC. In addition, our study shows that in humans the anterior half of the IC is occupied by the prefrontal cortex. Conclusion:This map may be of clinical use for correlating neurological deficit with hemispheric lesions, particularly those that affect sensorimotor function.

“…Previously, an inverse dorsoventral topography of striatonigral projections has been described in many species including rat, cat, and monkey (Poirier and Giguere, 1980;Groenewegen and Russchen, 1984;Nauta and Domesick, 1984;Gerfen, 1985;Selemon and Goldman-Rakic, 1990;Hedreen and DeLong, 1991). A mediolateral topography of striatonigral projections has also been documented in the Fig.…”

The striatum receives topographic cortical inputs with the limbic lobe terminating in the ventral striatum and sensorimotor cortical regions terminating in the dorsolateral striatum. The organization of striatonigral projections originating from these different striatal territories was examined in primate by using several anterograde tracers.The ventral striatum innervates a large area of the substantia nigra, including the medial pars reticulata and much of the pars compacta. Moreover, projections from separate areas of the ventral striatum overlap considerably in the substantia nigra. No mediolateral or rostrocaudal topographic order is apparent, and the area of the substantia nigra associated with the ventral striatum is extensive. In contrast, the sensorimotor-related striatum innervates a limited region of the ventrolateral substantia nigra. Similar to ventral striatonigral projections, projections originating from different areas of the sensorimotor-related striatum send converging inputs to the substantia nigra. Sensorimotor-related striatonigral projections avoid the region of the dopaminergic neurons in the dorsal pars compacta. Striatonigral projections from the sensorimotor-related and ventral striatum do not overlap in the substantia nigra. Examination of the outputs of discrete striatal loci indicates that the organization of striatonigral projections is more related to corticostriatal inputs than to a simple rostrocaudal, dorsoventral, or mediolateral topography of the striatum.Striatal projections that originate from different striatal territories are distinct and nonoverlapping, thus supporting the concept of segregated striatonigral circuits. However, areas of the striatum that receive common cortical inputs send converging inputs to the substantia nigra. This suggests that the substantia nigra is also an important link for integrating information between functionally related (sublcircuits.
