The project ERC-MINING: Fiber optics as a probe for brain health

Capturing the dynamics of brain activity across its various components—by deciphering the complex electrical and chemical signaling exchanged by the different constituents of brain tissue—represents a fundamental challenge for neural interfaces.

MINING aims to create a new class of multifunctional neural endoscopes capable of both stimulating and detecting electrical and molecular signals with cellular resolution *in vivo* throughout a volume of brain tissue. The result will be an unprecedented ability to correlate multiple signal types within the same volume, achieving high spatial and temporal resolution at depth. Current state-of-the-art limitations will be overcome by leveraging light-matter interactions in hybrid metal-dielectric metasurfaces and their synergistic integration with organic electrochemical transistors.
