Magnetic resonance imaging uses magnetic resonance to examine biological structures. Functional MRI extends this approach through blood-oxygen-related contrast, allowing researchers to study activity in different parts of the brain.

49:43>> 1973 invention of structural and functional MRI. Something many folks have had to experience. >> Yes. Um we talked about magnetic resonance imaging with um block and pursel earlier. They discovered that bulk matter you could use magnetic resonance imaging to probe it. here um chemist Paul Lerbbor developed magnetic resonance imaging at Sunni Stony Brook and earned him the 2003 Nobel Prize in physiology and medicine. He applied that to biological specimen and over there on the right hand side we can see the inside of um a mouse with lungs and so on and so forth and he's like guys we can use this for medicine. Um later on
50:23biohysicist um Sei Ogawa at Bell Labs discovered that we can use the bold contrast which is the oxygen level to probe functional MRI in our brain and figure out what parts of the brain are lighting up when you do this or that. So all of that happens right here in America. Interestingly, another American company, MidJourney, is trying to upend the MRI industry with a new imaging product that they just released a couple of weeks ago that we will potentially cover in a future episode. Discovery of
