Executive Industry Relevance

Integrating high-density micro-electrocorticography (µECoG) with laminar polytrodes and optogenetics enables multiscale interrogation of cortical processing, bridging the gap between local neuronal activity and mesoscale cortical signals. This approach enhances predictive confidence in target validation and functional mapping, supporting translational continuity from preclinical models to human neuroscience. The methodology is strategically positioned to inform biomarker discovery and mechanistic de-risking in neurotherapeutic pipelines.
