Before Albert Hsiao became a radiologist, he didn’t know performing electrical measurements in the cerebellum of rats or learning about neural networks in college would be relevant to caring for patients today.

Not only can technology like this help tackle the looming doctor shortage, it provides "some hope for us to return to our roots as medical doctors" and "to be better listeners," Hsiao writes.
