マウス上結腸におけるカルシウムイメージング

Executive Industry Relevance

High-resolution calcium imaging in the mouse superior colliculus (SC) enables direct interrogation of neural coding underlying visual processing, supporting mechanistic de-risking at the target validation stage. The ability to capture both single-cell and whole-structure activity in awake animals provides predictive confidence for translational neuroscience and neuropharma portfolios. This dual-scale approach strengthens early discovery decisions and informs downstream assay development for visual system targets.
