Neuromodulacja indukowana ultradźwiękami za pomocą systemu mikroelektrod

Executive Industry Relevance

This method enables non-invasive modulation of human iPSC-derived neuronal networks using focused ultrasound, providing a scalable in vitro platform for target validation in neurotherapeutics. By quantifying changes in electrical activity via MEA readouts, it supports mechanistic de-risking of neuromodulatory mechanisms prior to in vivo studies. The approach enhances predictive confidence in early discovery by linking ultrasound parameters to functional neuronal responses in a disease-relevant human cellular system.
