High-performance neuroprosthetic control by an individual with tetraplegia. Three-dimensional control using an electrocorticographic brain-machine interface by an individual with tetraplegia. We implanted two channel intracortical microelectrodes in the motor cortex of a year-old individual with tetraplegia.
High-performance neuroprosthetic control by an individual with tetraplegia.
For reference, four-dimensional training began on day 24 and seven-dimensional training on day Neural some of the methods used in this study. We therefore tested whether an individual with tetraplegia could rapidly achieve neurological control of a high-performance prosthetic limb using this type of an interface.
Cortical control of a prosthetic arm for self-feeding.

We implanted two channel intracortical microelectrodes in the motor cortex of a year-old individual with tetraplegia.
The blue dots represent the number of neural units recorded during brain—machine-interface sessions done A maximum movement time of 10 s was enforced for each 10—98 days after the implant.
Mean sistently on all 4 days of testing. We therefore tested whether an individual with tetraplegia could rapidly achieve insividual control of a high-performance prosthetic limb using this type of an interface. Weber ; John Edward Downey.

J Rehabil Res Dev ; Paralysis or high-perflrmance of an arm results in the loss of the ability to orient the hand and grasp, manipulate, and carry objects, functions that are essential for activities of daily living.
