Neuroscience and brain-computer interfaces
Brain mapping, neural implants and interfaces that connect brains and computers.
- WikiBRAIN InitiativeThe US BRAIN Initiative funds neurotechnology and brain-mapping research. Its 2013 launch, budget swings from $680 million to $320 million, and 2026 rebound.Updated
- WikiMICrONS ProjectMICrONS mapped the wiring and activity of one cubic millimetre of mouse visual cortex: over 200,000 cells and 523 million synapses, released openly in 2025.Updated
- WikiNeuralinkNeuralink develops the N1, a wireless brain implant placed by a surgical robot. Its trials, reported results, safety record and what remains unproven.Updated
- WikiNeuropixelsNeuropixels are chip-based silicon probes that record hundreds of single neurons at once. How they work, the 2.0 version and first uses in people.Updated
- WikiParadromicsParadromics builds Connexus, a fully implanted high-channel brain-computer interface for restoring speech. Its FDA-approved trial and first results.Updated
- WikiPrecision NeurosciencePrecision Neuroscience makes Layer 7, a thin-film brain surface array with 1,024 electrodes and FDA clearance for up to 30 days of implantation.Updated
- WikiSpeech neuroprosthesesSpeech neuroprostheses decode attempted speech from the brain into text or a synthetic voice for people with paralysis. Key results, limits and trials.Updated
- WikiSynchronSynchron's Stentrode is a brain-computer interface delivered through the blood vessels, avoiding open-brain surgery. Its trials, safety data and plans.Updated
- WikiUtah arrayThe Utah array is a grid of microelectrodes pushed into the cortex. It powered most landmark BCI studies, from cursor control in 2006 to speech in 2024.Updated
- AnalysisAre brain implants ready to become medical products?China approved an invasive BCI in 2026 and US firms are preparing pivotal trials. The evidence for and against implanted BCIs being ready for market.Updated
- AnalysisMental privacy: should neural data get special protection?Speech BCIs can now decode some inner speech, and laws are catching up. The debate over protecting neural data, from UNESCO to Colorado and the MIND Act.Updated
- ExplainerHow brain-computer interfaces workMeasure, decode, control: how a brain-computer interface turns neural activity into cursor movement, text or a synthesized voice, and how it is measured.Updated
- ExplainerHow brain mapping and connectomics workHow scientists map every neuron and synapse with electron microscopy and AI, from the whole fly brain to a cubic millimetre of mouse and human cortex.Updated
- ExplainerHow scientists record brain activityFrom scalp caps to electrodes inside the cortex: how neural recording works, what each method can see, and the trade-off between signal and surgery.Updated
