ALS

漸凍人 (Amyotrophic Lateral Sclerosis or commonly known as Lou Gehrig's disease) may be able to use their "mind" to control robotic limb to do basically any simple activities that their sclerotic muscle cannot handle any more. This is not new but usually it needs to have risky implanted electrodes BENEATH the cortex. New technology will allow electrodes ABOVE the cortex to transmit human's mind to the robotic limb. Hopefully, in the near future, these brain electrodes will be as safe as implanted cardio-defibrillators. Further research on BMI (brain-machine interface) will make all the recent zealous philanthropic activities for 漸凍人 pay off.
