A Brain-Computer Interface (BCI) represents a convergence of [[neuroscience]] and technology, enabling seamless communication between the brain and electronic devices. It works by detecting brain signals through [[sensors]], then processing these signals with algorithms to convert thoughts or neural activities into commands. These commands can control external devices, with applications mainly in medical [[rehabilitation]], such as helping individuals with disabilities. Beyond healthcare, BCIs are being developed for use in enhancing cognitive functions and interacting with digital platforms, expanding the scope of [[human-machine collaboration]]. The evolution of BCI technology marks a significant step in addressing neurological challenges and improving interaction with technology. In 2024, the BCI sector is led by companies innovating at the intersection of neuroscience and technology to enhance [[human-machine integration]]: 1. **[[🏦 Neuralink]]**: Advances in implantable BCIs to enhance human capabilities, focusing on treatments for neurological conditions and facilitating brain-computer communication. 2. **[[Synchron]]**: Pioneers in utilizing blood vessels for signal capture, offering a less invasive BCI solution through its Stentrode system. 3. **[[ClearPoint Neuro]] & [[Blackrock Neurotech]]**: Collaborating on automated BCI implantation solutions, aiming to improve surgical outcomes for neurological disorders【17†source】. 4. **[[BrainGate]]**: Offers technology allowing users to control external devices through thought, providing independence to those with severe paralysis 5. **[[CTRL-Labs]]** (acquired by [[🏦 Meta ($META)|Facebook]], now [[🏦 Meta ($META)|Meta Platforms]]): specialized in developing non-invasive neural interface technology, particularly in translating neural impulses into digital commands.
