Anatomofunctional organization of the insular cortex

We combine architectonic, tract-tracing, fMRI and electrophysiology to examine the anatomofunctional organization of the insular cortex in the macaque monkey. Multi-stain architectonic enables the parcellation of each of the three classical sectors of the insula into several distinct sub-sectors or areas. MRI-guided injections of high-resolution tracers in each of these areas are made to examine their individual patterns of connectivity. Some of our tracer injections are coupled with fMRI experiments in which we use interoceptive stimuli to activate specific sub-regions of the insular cortex. Thus, the coupling of tracing and fMRI provides both anatomical and functional information on the regions of interest. We complement our fMRI results with electrophysiological recordings. Finally, in order to examine the transposability of our findings in the monkey to humans, we use, among other approaches, comparative architectonic examinations across primates.
