Restoring tactile and proprioceptive sensation through a brain interface

Neurobiology of Disease, 2015
Somatosensation plays a critical role in the dexterous manipulation of objects, in emotional communication, and in the embodiment of our limbs. For upper-limb neuroprostheses to be adopted by prospective users, prosthetic limbs will thus need to provide ...

Direct visualization of microwires in hybrid depth electrodes using high‐resolution photon‐counting CT

Epilepsia Open, Volume 9, Issue 6, Page 2518-2521, December 2024.
Abstract Hybrid depth electrodes are increasingly being used for epilepsy monitoring and human neurophysiology research. Microwires extending from the tip of the Behnke‐Fried (BF) electrode into (sub)cortical areas allow to isolate single neurons and perform microstimulation.

Neural–Computer Interfaces: Theory, Practice, Perspectives

Applied Sciences
This review outlines the technological principles of neural–computer interface (NCI) construction, classifying them according to: (1) the degree of intervention (invasive, semi-invasive, and non-invasive); (2) the direction of signal communication ...

Long-term stability of sensitivity to intracortical microstimulation of somatosensory cortex

Journal of Neural Engineering, 2015
The dexterous manipulation of objects depends heavily on somatosensory signals from the limb. The development of anthropomorphic robotic arms and of algorithms to decode intended movements from neuronal signals has stimulated the need to restore somatosensation for use in upper-limb neuroprostheses.

Sensory Survey 3-D: An Open Source Utility for the Annotation of Projected Fields for Sensory Neural Interfaces

IEEE Transactions on Neural Systems and Rehabilitation Engineering
One goal of neuroprosthetics is to restore sensation to those who have lost it due to disease or injury. This is often accomplished with electrical stimulation of nervous tissue.

Behavioral detection of intra-cortical microstimulation in the primary and secondary auditory cortex of cats

Frontiers in Systems Neuroscience, 2015
Although neural responses to sound stimuli have been thoroughly investigated in various areas of the auditory cortex, the results electrophysiological recordings cannot establish a causal link between neural activation and brain function.

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.

Linking spatially distributed neuronal activation overlap to the limits of perceptual discrimination in rodent primary somatosensory cortex

Frontiers in Computational Neuroscience
IntroductionIntracortical microstimulation (ICMS) of the primary somatosensory cortex can evoke localized tactile percepts, yet the spatial factors that influence perceptual discrimination remain poorly defined.

A Machine Learning-Based Decoder Framework for the Cortical Voltage-Sensitive Dye Responses to Retinal Neuromorphic Microstimulation: A Proof-of-Concept Simulation Study

Bioengineering
Intracortical microstimulation (ICMS) is a promising approach for visual prostheses. We recently proposed using retinal neuromorphic spike trains derived from visual images as ICMS pulse sequences, and preliminarily recorded cortical voltage-sensitive ...
