Highly sensitive sensors have been successfully used to map the electrical activity of the developing heart in embryos, in a University of Sussex study published today (10 November 2015).
The study could lead to new insight into how heart rhythm abnormalities develop, the researchers say.
The team fine-tuned patented Electric Potential Sensing (EPS) technology, developed at the University, to detect the electrical signals of zebrafish embryos from just three days after fertilization. The findings have been published in the scientific journal Applied Physics Letters.
