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 ...

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 ...

Layer-specific parameters of intracortical microstimulation of the somatosensory cortex. [PDF]

J Neural Eng, 2021
Abstract Objective . Intracortical microstimulation of the primary somatosensory cortex (S1) has shown great progress in restoring touch sensations to patients with paralysis. Stimulation parameters such as amplitude, phase duration, and frequency can influence the quality of the evoked percept

Subthreshold intracortical microstimulation of human somatosensory cortex enhances tactile sensitivity [PDF]

Brain Stimulation
Background: Intracortical microstimulation (ICMS) of the somatosensory cortex activates neurons around the stimulating electrodes and can elicit tactile sensations. Objective: It is not clear how the direct activation of cortical neurons influences their

Neural mechanisms underlying intracortical microstimulation for sensory restoration. [PDF]

Nat Biomed Eng
Sensation plays a pivotal role in the orchestration of our daily lives. Intracortical microstimulation (ICMS) can elicit artificial sensations in persons who have lost sensation due to neurological injury or disease. Despite ongoing clinical studies to assess the safety and efficacy of ICMS, the mechanisms underlying neural activation by ICMS and their

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).
