Valle, G., Oswalt, D., Gaunt, R. A., Roelfsema, P., Greenspon, C. M., Fernandez, E. Abstract The restoration of sensory function following injury or disease represents a critical challenge in neuroengineering. Sensory neuroprostheses, particularly those targeting the primary visual (V1) and somatosensory (S1) cortices, promise to bypass damaged afferent pathways and reintroduce sensory percepts through direct cortical stimulation. Building on foundational insights from non-hu

Valle, G. Abstract Somatosensory feedback is an essential feature of neural prostheses that aim to restore natural hand dexterity after neurological injuries. This Comment discusses the potential and challenges of electrically stimulating sensory neurons, highlighting the need for highly selective neurotechnology and biomimetic-encoding algorithms for effective brain–machine interfacing.

Valle, G., Alamri, A. H., Downey, J. E., Lienkämper, R., Jordan, P. M., Sobinov, A. R., Endsley, L. J., Prasad, D., Boninger, M. L., Collinger, J. L., Warnke, P. C., Hatsopoulos, N. G., Miller, L. E., Gaunt, R. A., Greenspon, C. M., Bensmaia, S. J. Abstract Intracortical microstimulation (ICMS) of somatosensory cortex evokes tactile sensations whose properties can be systematically manipulated by varying stimulation parameters. However, ICMS currently provides an imperfect s

M., Weiss, J. M., Fitzgerald, E. E., Prasad, E., Van Driesche, A., He, Q., Liu, F., Kirsch, R. F., Miller, J. P., Lee, R. C., Satzer, D., Gonzalez-Martinez, J., Warnke, P. C., Bensmaia, S. J. Abstract Tactile feedback from brain-controlled bionic hands can be partially restored via intracor

Salas, M. A., Bashford, L., Kellis, S., Jafari, M., Jo, HyeongChan, Kramer, D., Shanfield, K., Pejsa, K., Lee, B. Liu, C. Y., Andersen, R. A. Abstact 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 yet provide the breadth of cutaneous and proprioceptive percepts available
