Different ideas exist about possible targets for biological effects of electromagnetic fields (EMF). One of the favourite systems are the membranes of nerve cells, e.g. in the central nervous system. Our aim is to clarify whether EMF exposure may induce athermal effects. In the experiments, direct electrophysiological in vitro measurements are conducted on neuronal networks exposed to EMF, i.e. possible changes in the action potential patterns produced by the networks are detected. The technique was developed as an alternative to the common patch-clamp approach.
These results support the use of hSC-CM and MEA technology for preclinical assessment of proarrhythmic risk within the proposed CiPA paradigm, and, more generally, demonstrate that automation of the CM-MEA assay can achieve high reliability and throughput for cardiac risk assessment in vitro.READ MORE
