Free Will has been a philosophical debate for as long as philosophical debates have existed and science has weighed in from time to time. Neuroscience really started its proper discussion of if humans are truly free with the work of Libet in 1985, although even Libet was working off earlier work. That research brought into the public mind the question of it the readiness potential, the charging up of your motor system to fire, could answer if humans are free or not. We are not 37 years after the initial study and new research is not questioning if free will is real, or if neuroscience has ways to answer the question but if the readiness potential is the best way to find out. In this episode, we dive into the methods behind the readiness potential and try to see if it is something from an era of neuroscience that we can replace now.
