Outline of Final Research Achievements |
The aims of the present project were to investigate; 1) the neural activity within the premotor-insula-parietal regions in the macaque monkey; 2) the neural network between the ventral premotor (PMv) areas and the basal ganglia (BG) or the amygdala (Amyg). To this purpose monkeys were tested in sensory (visual, somatosensory)-motor tasks. Further, we employed retrograde transneuronal labeling with rabies virus to identify the origins of multisynaptic projections from the BG/Amyg to the PMv in macaque monkeys. As so for, the results showed that neurons in the insular cortex were active during hand-mouth movement and during passive tactile stimulation. Further, PMv receives inputs from motor and limbic territories of BG/Amyg. Our results suggested that the frontal-parietal network is involved in both motor and limbic cognitions.
