DESCRIPTION:Joseph E. O Doherty\, University of California\nI will discuss
  the development of a brain-machine-brain interface (BMBI) which enables a
 rtificial 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 p
 atterned ICMS pulse trains enable artificial active exploration\; that per
 iodic and aperiodic pulse trains are discriminable\, suggesting the potent
 ial for percept encoding beyond simple frequency codes\; and that complex 
 temporal patterns of ICMS can be used to convey information about the spat
 ial frequencies of artificial textures. These results suggest that future 
 clinical neuroprostheses could implement feedback of object-actuator inter
 actions 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
