Medical breakthrough: Brain chip allows paralyzed man to regain hand movement

The video discusses a medical breakthrough where a chip is implanted in a paralyzed patient's motor cortex to help regain movement. The chip records brain signals for hand movements, which are decoded and transmitted to an arm sleeve with electrodes. These electrodes stimulate muscles, allowing movement despite paralysis.
