Modeling Dynamic Receptive Field Changes Produced by Intracortical Microstimulation

, 1998
Intracortical microstimulation (ICMS) of a localized site in the somatosensory cortex of rats and monkeys produces reorganization of receptive field (RF) topography over a large region of the cortex.1 ICMS excites nearly all afferents and excitatory and inhibitory cortical neurons within a few microns of the stimulating electrode.

Sensitivity to microstimulation of somatosensory cortex distributed over multiple electrodes

Frontiers in Systems Neuroscience, 2015
Meaningful and repeatable tactile sensations can be evoked by electrically stimulating primary somatosensory cortex. Intracortical microstimulation (ICMS) may thus be a viable approach to restore the sense of touch in individuals who have lost it, for ...

Injecting information in the cortical reach-to-grasp network is effective in ventral but not dorsal nodes

Cell Reports
Summary: Although control of movement involves many cortical association areas, bidirectional brain-machine interfaces (BMIs) typically decode movement intent from the motor cortex and deliver feedback information to the primary somatosensory cortex (S1).

Spatiotemporal properties of cortical excitatory and inhibitory neuron activation by sustained and bursting electrical microstimulation

iScience
Summary: Intracortical microstimulation (ICMS) of sensory brain regions can create artificial sensations, yet these percepts fade with continued stimulation, suggesting dynamic changes in underlying neural activity. Using two-photon imaging in transgenic

Continuous sensorimotor transformation enhances robustness of neural dynamics to perturbation in macaque motor cortex

Nature Communications
Neural activity in the motor cortex evolves dynamically to prepare and generate movement. Here, we investigate how motor cortical dynamics adapt to dynamic environments and whether these adaptations influence robustness against disruptions.
