Este artigo descreve um método para analisar as propriedades do espaço extracelular em fatias cerebrais usando microeletrodos seletivos de íons. A técnica envolve medir a difusão de íons tetrametilamonio para avaliar a fração do volume extracelular e outros parâmetros.
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.
