Enregistrement et coloration juxtacellulaires pour une cartographie précise de l’activité neuronale chez un rat éveillé

Executive Industry Relevance

Precise mapping of neural activity to anatomical structures is critical for target validation and mechanistic de-risking in CNS drug discovery. Juxtacellular recording and staining in awake rats enables high-resolution correlation of functional neuronal signals with exact brain locations, supporting predictive confidence in early-stage neuropharmacology. This capability strengthens translational continuity from discovery through preclinical model development.
