Intracortical microstimulation of human somatosensory cortex [PDF]

Science Translational Medicine, 2016
Tactile percepts were consistently elicited in the hand of a person with cervical spinal cord injury using intracortical microstimulation of the somatosensory cortex.

Intracortical Microstimulation of Bilateral Frontal Eye Field [PDF]

Journal of Neurophysiology, 1998
Fujii, Naotaka, Hajime Mushiake, and Jun Tanji. Intracortical microstimulation of bilateral frontal eye field. J. Neurophysiol. 79: 2240–2244, 1998. We trained two monkeys to perform a fixation task. Intracortical microstimulation (ICMS) was applied to the monkey frontal eye field (FEF) while monkeys were fixating on one of five fixation LEDs.

Neuroengineering Tools For Studying The Effect Of Intracortical Microstimulation In Rodent Models [PDF]

2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018
Intracortical microstimulation can be successfully used to manipulate neuronal activity and connectivity, thus representing a potentially powerful tool to steer neuroplasticity occurring after brain injury. Activity-dependent stimulation (ADS), in which the spikes recorded from a single neuron are used to trigger stimulation at another cortical ...

A reappraisal of rat motor cortex organization by intracortical microstimulation

Brain Research, 1985
The organization of the motor cortex was reinvestigated with intracortical microstimulation, in light-anaesthetized (ketamine) rats. A posterolateral (PL) vibrissae area was found in addition to the rostral one, and blinks of the contralateral eyelids were elicited from a part of this PL area.

A Miniaturized System for Spike-Triggered Intracortical Microstimulation in an Ambulatory Rat

IEEE Transactions on Biomedical Engineering, 2011
This paper reports on a miniaturized system for spike-triggered intracortical microstimulation (ICMS) in an ambulatory rat. The head-mounted microdevice comprises a previously developed application-specific integrated circuit fabricated in 0.35-μm two-poly four-metal complementary metal-oxide-semiconductor technology, which is assembled and packaged on

Ultrasonically-assisted intracortical microstimulation of the rat

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
High frequency tone bursts of ultrasound are capable of increasing the sensitivity of rat motor cortex to electrical stimulation. In this study, 11.75 MHz ultrasound pre-stimuli were delivered to the forelimb motor region of the rat cortex followed by an electrical pulse train to assess changes in cortical activation. The temporal peak intensity of the

Intracortical microstimulation of neurons in the visual cortex of the cat

Electroencephalography and Clinical Neurophysiology, 1981
The response of visual cortex neurons to local intracortical microstimulation was measured in the anesthetized cat. When the recording microelectrode was very close (about 20 micrometers) to the tip of the stimulating electrode, threshold currents as low as 10 micro A were capable of firing neurons.

Excitation of visual cortex neurons by local intracortical microstimulation

Experimental Neurology, 1983
The threshold current required for the excitation of visual cortex neurons in the vicinity (approximately 1 mm) of an intracortical stimulating electrode was measured as a function of the stimulus pulse duration in the anesthetized cat. For cortical neurons with latencies of activation from 0.4 to 3.4 ms and for stimulus pulse durations from 0.02 to 0 ...
