Microelectrode 배열 마이크로 신경 통신 및 Axonal 신호 전파 공부에 대 한 인터페이스

Executive Industry Relevance

This microfluidic-MEA platform addresses a key challenge in neuroscience drug discovery: isolating axonal signal propagation from somatic noise in neuronal cultures. By enabling high-resolution, long-term recording of spike propagation with improved signal-to-noise ratio, the method supports mechanistic de-risking of targets involved in neurodevelopment, neurodegeneration, and neuroregeneration. It provides predictive confidence in early discovery by quantifying communication-related phenotypes such as conduction velocity and firing patterns.
