And why is that the case ? Because bird brains undergoes new neurogenesis in a way that human or mammal brains don't . Uh And it was the new neurons that were coming in into the circuit uh but not quite , you know , with the right proper activity uh was resulting in this stuttering in these birds .

Uh And after it was repaired , not exactly the old song came back as after the repair , but still , it recovered a lot better . And it's now known they call this neurogen neurogenic stuttering in humans . Uh would be damage to the basal ganglia or some type of disruption to the basal ganglia at a young age also causes stuttering in humans and even those who are born with stuttering .

So we actually uh accidentally came across stuttering in songbirds . And we've published several papers on this to try to figure out the neurobiological basis . The first study we had was a brain area called the basal ganglia .

This what's the the striatum part of the basal ganglia involved in coordinating movements , learning how to make movements when it was damaged in these , in this , in a speech like pathway in these birds .
