Low-threshold, high-resolution, chronically stable intracortical microstimulation by ultraflexible electrodes [PDF]
Cell Reports, 2023 Summary: Intracortical microstimulation (ICMS) enables applications ranging from neuroprosthetics to causal circuit manipulations. However, the resolution, efficacy, and chronic stability of neuromodulation are often compromised by adverse tissue ...

Intracortical microstimulation of human somatosensory cortex induces natural perceptual biases [PDF]
Brain StimulationTime-order error, a psychophysical phenomenon in which the duration in between successive stimuli alters perception, has been studied for decades by neuroscientists and psychologists. To date, however, the locus of these effects is unknown.

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 ...

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

The Role of Electrode-Site Placement in the Long-Term Stability of Intracortical Microstimulation [PDF]
Frontiers in Neuroscience, 2021 Intracortical microelectrodes are neuroprosthetic devices used in brain-machine interfaces to both record and stimulate neural activity in the brain. These technologies have been improved by advances in microfabrication, which have led to the creation of

Amplitude- and frequency-dependent activation of layer II/III neurons by intracortical microstimulation [PDF]
iScience, 2023 Summary: Intracortical microstimulation (ICMS) has been used for the development of brain machine interfaces. However, further understanding about the spatiotemporal responses of neurons to different electrical stimulation parameters is necessary to ...

Responses of Cortical Neurons to Intracortical Microstimulation in Awake Primates. [PDF]
eNeuro, 2023 Abstract Intracortical microstimulation (ICMS) is commonly used in many experimental and clinical paradigms; however, its effects on the activation of neurons are still not completely understood. To document the responses of cortical neurons in awake nonhuman primates to stimulation, we recorded single-unit activity while delivering ...
