Disparity-defined 3D shape is processed in both the ventral and the dorsal visual stream. The network of cortical areas that is activated during the processing of disparity-defined 3D shape includes, in addition to parietal and premotor areas, three clearly distinct regions in inferotemporal cortex (ITC). To investigate the connectivity of the latter regions, we combined electrical stimulation with fMRI in male macaque monkeys. Electrical stimulation of each of the 3D-structure nodes in ITC mainly elicited increased fMRI activations in the other 3D-structure nodes and more variably in other parts of ventral visual cortex. Importantly, no increased activation was found in parietal areas, nor in PFC, whereas microstimulation in posterior parietal cortex did activate the ITC. Our results indicate that 3D-structure nodes in ITC form a strongly interconnected network, receiving input from parietal areas implicated in 3D-structure processing.
