neurallink

Neurallink is a term used to describe a brain–computer interface concept or brand name that denotes a direct communication link between neural tissue and computer systems. The spelling with two l’s is uncommon in published literature, and in many discussions the term is conflated with Neuralink, a real company pursuing similar goals. In general, a neurallink envisions hardware that interfaces with the brain—implantable or wearable—with software that decodes neural signals to control external devices and, in some designs, delivers stimuli to the nervous system.

Technologies associated with neurallinks span invasive and non-invasive approaches. Invasive methods rely on implanted electrode arrays and wireless transmitters embedded in neural tissue, paired with biocompatible materials to minimize adverse reactions. Non-invasive methods use electroencephalography (EEG), magnetoencephalography (MEG), transcranial magnetic stimulation (TMS), or focused ultrasound to interact with brain activity from outside the skull. Across approaches, advances in signal processing and machine learning aim to improve the accuracy and speed of neural decoding and the precision of neural stimulation.

Applications broadly cover medical and assistive aims, such as restoring motor function after paralysis, aiding communication for people with severe disabilities, and providing new avenues for neurorehabilitation. Research also explores sensory restoration, basic neuroscience, and potential, more speculative, cognitive augmentation. Ethical, safety, and regulatory considerations focus on biocompatibility, long-term implant viability, privacy of neural data, informed consent, and the societal implications of enhanced human capabilities.

Status and specifics vary by project; neurallink remains a general term rather than a standardized technology, with real-world efforts ongoing under broader brain–computer interface research.
