Abstract: The intracortical microstimulation (ICMS) from 40 to 100 µA is useful to elicit tactile sensations, which could be employed in neuroprostheses to control the robotic arms’ movement. However, this electrical current applied for prolonged periods of time could damage the neuronal tissue. Therefore, there is a necessity to create new strategies for the practical use of ICMS in a safe intensity range for potential clinical applications in tetraplegic patients. Here we describe crucial studies supporting the use of electrical and optical noise to guarantee a safe ICMS delivered through brain-machine interface technologies.
