Advanced Research and Invention Agency (ARIA) is a UK government-funded research agency established to support high-risk, high-reward scientific and technological research. Modeled partly on DARPA, it operates independently to fund breakthrough programs across multiple domains, with a significant allocation to neurotechnology.

The agency has committed substantial resources to neuroscience, including approximately GBP 69 million through its Precision Neurotechnologies program and GBP 50 million through its Massively Scalable Neurotechnologies program. These initiatives focus on non-invasive neural interfaces, remote interfaces, and biological interfaces for brain-machine communication.

ARIA's geographic focus is primarily the United Kingdom, though it supports international research partnerships. Its funding is non-dilutive and targets pre-commercial and fundamental research stages, positioning it as a critical enabler of early-stage neurotechnology development in Europe.
