Virtual active touch using randomly patterned intracortical microstimulation. [PDF]
IEEE Trans Neural Syst Rehabil Eng, 2012 Intracortical microstimulation (ICMS) has promise as a means for delivering somatosensory feedback in neuroprosthetic systems. Various tactile sensations could be encoded by temporal, spatial, or spatiotemporal patterns of ICMS. However, the applicability of temporal patterns of ICMS to artificial tactile sensation during active exploration is unknown,

A computational model that predicts behavioral sensitivity to intracortical microstimulation. [PDF]
J Neural Eng, 2017 Intracortical microstimulation (ICMS) is a powerful tool to investigate the neural mechanisms of perception and can be used to restore sensation for patients who have lost it. While sensitivity to ICMS has previously been characterized, no systematic framework has been developed to summarize the detectability of individual ICMS pulse trains or the ...

Muscle synergies evoked by microstimulation are preferentially encoded during behavior
Frontiers in Computational Neuroscience, 2014 Electrical microstimulation studies provide some of the most direct evidence for the neural representation of muscle synergies. These synergies, i.e. coordinated activations of groups of muscles, have been proposed as building blocks for the construction

Characterizing Evoked Movement Patterns and Connectivity in Sensorimotor Cortex After Sensory Loss in Squirrel Monkeys. [PDF]
J Comp NeurolExcitability to long‐train intracortical microstimulation in the primary somatosensory cortex after recovery from long‐term sensory loss tended to be altered but was not statistically different from that of normal and intact hemispheres. Cortical connection patterns of areas 3b and M1 were consistent with early findings, characterized by the presence ...

Brain Stimulation, 2022 Background: Intracortical microstimulation (ICMS) of somatosensory cortex can partially restore the sense of touch. Though ICMS bypasses much of the neuraxis, prior studies have found that conscious detection of touch elicited by ICMS lags behind the ...

The functional consequences of chronic, physiologically effective intracortical microstimulation. [PDF]
Prog Brain Res, 2011 Many studies have demonstrated the ability of chronically implanted multielectrode arrays (MEAs) to extract information from the motor cortex of both humans and nonhuman primates. Similarly, many studies have shown the ability of intracortical microstimulation to impart information to the brain via a single or a few electrodes acutely implanted in ...
