Magneto Protein Could Help Magnets Control Brain Circuitry

This groundbreaking research by scientists at the University of Virginia has demonstrated a novel way to control the nervous systems of zebrafish and mice using magnets. This method, called magnetogenetics, involves inserting genetic constructs into neurons to make them sensitive to magnetic fields, providing a more precise and non-invasive way to control and manipulate neural circuits than traditional methods. This could one day revolutionize the treatment of brain disorders in humans. Read full article here
