The cortical connections of the areas of the dorsal bank of the intraparietal sulcus: histological studies and perspectives from probabilistic tractography

The corticocortical connections of the areas of the dorsal bank of the intraparietal sulcus (IPS) of macaque monkeys were studied by means of retrograde tracers injections in order to provide histological basis for the tractography analysis. The combined approach of these two techniques allows direct comparison of the results and a cross-validation of both methodological approaches. However, only preliminary results and perspectives from tractography analysis were included in the present thesis. Instead, tangential and laminar distribution and topographical aspects of the projections to the dorsal bank of the IPS were discussed, together with the relationships between parieto-frontal connectivity and corticospinal systems.
