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

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.

Local Neuronal Responses to Intracortical Microstimulation in Rats' Barrel Cortex Are Dependent on Behavioral Context [PDF]
Frontiers in Behavioral Neuroscience, 2022 The goal of cortical neuroprosthetics is to imprint sensory information as precisely as possible directly into cortical networks. Sensory processing, however, is dependent on the behavioral context.
