Ten artykuł opisuje metodę analizy właściwości przestrzeni pozakomórkowej w kronach mózgu za pomocą jonoselektywnych mikroelektrod. Technika polega na pomiarze dyfuzji jonów tetrametyloamoniowych w celu oceny ułamka objętości pozakomórkowej i innych parametrów.
Quantitative characterization of brain extracellular space using ion-selective and iontophoresis microelectrodes enables precise measurement of volume fraction and tortuosity, critical for understanding molecular diffusion in neural tissue. This capability supports early-stage neuroscience drug discovery by informing target engagement and compound distribution in physiologically relevant environments. Reliable extracellular space metrics enhance predictive confidence for CNS-targeted portfolios and translational research.
This method integrates into the discovery-to-preclinical continuum by providing quantitative extracellular space metrics essential for CNS drug development.
