Executive Industry Relevance

High-resolution structural MRI of the human subcortex enables precise delineation of small nuclei, directly impacting early discovery and translational neuroscience pipelines. By defining the resolution limits and noise constraints in both postmortem and in vivo settings, this protocol informs predictive confidence for subcortical target identification and quantitative biomarker development. The approach supports risk-adjusted decisions in neurotherapeutic portfolio advancement by clarifying anatomical boundaries critical for mechanistic de-risking.
