Sensitivity to microstimulation of somatosensory cortex distributed over multiple electrodes

open access: yesFrontiers 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 ...

The Development of Complex Movement Motor Maps Using Long Duration Intracortical Microstimulation (LD-ICMS) in Rats [PDF]

open access: yes, 2014
The adult motor cortex is topographically organized into representations (maps) of different body parts (Fritsch & Hitzig, 1870; Ferrier, 1873). Recent evidence, however suggests a movement-based, rather than, muscle-based cortical motor organization

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

open access: yesCell 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

open access: yesiScience
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

Variable somatosensory cortical representation of the rat vibrissae following short-term intracortical electrical microstimulation: A combined electrophysiological and metabolic investigation [PDF]

open access: yes, 1993
The cortical representation of the rodent vibrissae is highly organized, with a 1:1 correlation between a vibrissae and its cortical layer IV barrel .

Intracortical microstimulation of human somatosensory cortex as a source of cutaneous feedback [PDF]

open access: yes, 2018
The field of brain computer interfaces (BCI) has been making rapid advances in decoding brain activity into control signals capable of operating neural prosthetic devices, such as dexterous robotic arms and computer cursors.

Spatially and temporally mismatched blood flow and neuronal activity by high-intensity intracortical microstimulation

open access: yesBrain Stimulation
Introduction: Intracortial microstimulation (ICMS) is widely used in neuroprosthetic brain-machine interfacing, particularly in restoring lost sensory and motor functions.

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

open access: yesNature 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.
