Neuralink is a brain-machine interface company founded by Elon Musk that is developing implantable brain-computer interfaces or "neural laces." The technology involves implanting tiny threads containing electrodes into the brain that can read neuron activity. These signals are transmitted wirelessly to a device outside the skull and can interface with computers. Potential applications include helping treat neurological conditions like Alzheimer's, providing a visual prosthesis for blindness, enabling telepathy-like communication, and allowing for enhanced memory recall. While promising benefits, some have concerns about risks from an electronic device implanted in the brain.
