I will discuss the development of a brain-machine-brain interface (BMBI) which enables artificial tactile sensation through intracortical microstimulation (ICMS) of primary somatosensory cortex (S1). Rhesus monkeys operated this BMBI to search through sets of objects with an upper limb avatar and select those with particular artificial textures. I will demonstrate that temporally patterned ICMS pulse trains enable artificial active exploration; that periodic and aperiodic pulse trains are discriminable, suggesting the potential for percept encoding beyond simple frequency codes; and that complex temporal patterns of ICMS can be used to convey information about the spatial frequencies of artificial textures. These results suggest that future clinical neuroprostheses could implement feedback of object-actuator interactions through ICMS to generate somatic sensations from the prosthesis, leading to greater dexterity and the incorporation of the prosthesis into the user's body schema
