Conveying tactile object characteristics through customized intracortical microstimulation of the human somatosensory cortex [PDF]
Nature CommunicationsMicrostimulation of the somatosensory cortex can evoke tactile percepts in people with spinal cord injury, providing a means to restore touch. While location and intensity can be reliably conveyed, two issues that prevent creating more complex ...

Investigating the spatial limits of somatotopic and depth-dependent sensory discrimination stimuli in rats via intracortical microstimulation [PDF]
Frontiers in NeuroscienceThe somatosensory cortex can be electrically stimulated via intracortical microelectrode arrays (MEAs) to induce a range of vibrotactile sensations. While previous studies have employed multi-shank MEA configurations to map somatotopic relationships, the

Proprioceptive and cutaneous sensations in humans elicited by intracortical microstimulation [PDF]
eLife, 2018 Pioneering work with nonhuman primates and recent human studies established intracortical microstimulation (ICMS) in primary somatosensory cortex (S1) as a method of inducing discriminable artificial sensation. However, these artificial sensations do not

Discriminability of Single and Multichannel Intracortical Microstimulation within Somatosensory Cortex [PDF]
Frontiers in Bioengineering and Biotechnology, 2016 The addition of tactile and proprioceptive feedback to neuroprosthetic limbs is expected to significantly improve the control of these devices. Intracortical microstimulation (ICMS) of somatosensory cortex is a promising method of delivering this ...
