Some amputees can move their prosthetics using their minds because of how neurons communicate. When a limb is lost, the neurons in the brain that originally controlled that limb remain active and can still send signals. Researchers use sensors to detect these signals, which come from the brain's receptors. Neuroglia support these neurons by maintaining the environment needed for proper signaling. By interpreting the brain's signals, the prosthetic can move in response to the user's thoughts, allowing for a more natural control of the device.
