What does the future of medicine look like? Precision, precision, precision. In the last few decades, neuroengineers have largely relied on optogenetics to achieve single neuron precision, but widespread application in the clinical setting has been hindered by the fact that to get the tech to work you have to have a light in the brain. Which is... invasive, to say the least. Enter magnetogenetics, the next generation of precision neuromedicine. By engineering cells that are responsive to external magnetic fields, researchers have started to demonstrate that not only is it theoretically possible to use magnetic fields to affect the behavior of neural circuits, it will likely be a practical technology in the clinical setting in the next few decades.  We talk with neuroengineer Dr. Jacob Robinson about the work his lab is doing, the state of the field, and how to escape the generator function that creates technologies that rule us, rather than the other way around.
