Neurogenic stuttering in humans can result from damage to the basal ganglia, particularly the speech area, at a young age.

“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 a after the repair but still it recovered a lot better and it's now known they call this neurogen neurogenics stuttering in humans uh with damage to the braz ganglia or some type of disruption to the basil ganglia at a young age also causes stuttering in humans and even those who are born with stuttering uh um it it's often the basil ganglia uh that's disrupted than some other brain circuit and we think the speech part of the basil ganglia.”
