Evoking stable and precise tactile sensations via multi-electrode intracortical microstimulation of the somatosensory cortex. [PDF]

Nat Biomed Eng
Tactile feedback from brain-controlled bionic hands can be partially restored via intracortical microstimulation (ICMS) of the primary somatosensory cortex.

A brain-machine interface instructed by direct intracortical microstimulation [PDF]

Frontiers in Integrative Neuroscience, 2009
Brain-machine interfaces (BMIs) establish direct communications between the brain and artificial actuators. As such, they hold considerable promise for restoring mobility and communication in patients suffering from severe body paralysis. To achieve this

The Long-Term Stability of Intracortical Microstimulation and the Foreign Body Response Are Layer Dependent. [PDF]

Front Neurosci, 2022
Intracortical microstimulation (ICMS) of the somatosensory cortex (S1) can restore sensory function in patients with paralysis. Studies assessing the stability of ICMS have reported heterogeneous responses across electrodes and over time, potentially ...

Biomimetic stimulation patterns drive natural artificial touch percepts using intracortical microstimulation in humans. [PDF]

J Neural Eng
Objective. Intracortical microstimulation (ICMS) of human somatosensory cortex evokes tactile percepts that people describe as originating from their own body, but are not always described as feeling natural.

Activation and depression of neural and hemodynamic responses induced by the intracortical microstimulation and visual stimulation in the mouse visual cortex. [PDF]

J Neural Eng
Objective. Intracortical microstimulation (ICMS) can be an effective method for restoring sensory perception in contemporary brain–machine interfaces. However, the mechanisms underlying better control of neuronal responses remain poorly understood, as ...

Intracortical microstimulation parameters modulate flight behavior in pigeon [PDF]

Journal of Integrative Neuroscience, 2019
Pigeons have a natural affinity for travel by flight. Researchers have recently achieved modulation of pigeon locomotor behaviour by intracortical microstimulation.

Intracortical microstimulation pulse waveform and frequency recruits distinct spatiotemporal patterns of cortical neuron and neuropil activation. [PDF]

J Neural Eng, 2022
Objective. Neural prosthetics often use intracortical microstimulation (ICMS) for sensory restoration. To restore natural and functional feedback, we must first understand how stimulation parameters influence the recruitment of neural populations.

Neural Modulation of the Primary Auditory Cortex by Intracortical Microstimulation with a Bio-Inspired Electronic System [PDF]

Bioengineering, 2020
Nowadays, the majority of the progress in the development of implantable neuroprostheses has been achieved by improving the knowledge of brain functions so as to restore sensorial impairments.

Intracortical microstimulation in humans: a decade of safety and efficacy

medRxiv
Background Intracortical microstimulation (ICMS) of somatosensory cortex can restore a sense of touch to people with spinal cord injury (SCI). In this early-feasibility clinical trial, we evaluate the safety, efficacy, and longevity of ICMS as there is a

Intracortical Microstimulation Modulates Cortical Induced Responses. [PDF]

J Neurosci, 2018
Recent advances in cortical prosthetics relied on intracortical microstimulation (ICMS) to activate the cortical neural network and convey information to the brain. Here we show that activity elicited by low-current ICMS modulates induced cortical responses to a sensory stimulus in the primary auditory cortex (A1).
