English: a) Cortical implants typically used for sensorimotor neuroprostheses can be divided into two categories: intracortical MEAs such as the Utah array (10 × 10 Utah array), and epidural or subdural ECoG strips or grids with different specifications (illustrated for a 8 × 8 ECoG grid, 4 mm contact diameter, 10 mm pitch, with permission from CorTec GmbH). These implants can both record neurophysiological signals and deliver electrical stimulation. b) Peripheral and spinal implants for sensorimotor neuroprostheses target either the motor nerves or muscles in the case of FES, the spinal cord in epidural SCS, or the sensory nerves in PNS for somatosensory feedback. All applications shown here used these implants for delivering electrical stimulation. Lightning bolts indicate neurostimulation.
