Right you're correct. The cerebellum was only mentioned as it relates brains scans taken from people who spontaneously recovered. But I think it gives us an indication on what brain region needed to be further developed in order to compensate for the structural deficiency scientists have observed in the left hemisphere. As you know, one of the key functions of the cerebellum is coordination. Coordination and movement. So maybe these recovered stutters have better coordination between the speech muscles when they say their usual problem sounds, so end up not blocking as hard or not at all. That's just a hypothesis but I don't think it's too far-fetched. Now what speech exercises have research showning to improve coordination when it comes to speech? Speech sound stimulability exercises. Yea that's a strange one. Vision and stuttering being related. It's hard to think that's possible. Because some people stutter even if they're alone in their room or on a phone call or drive-thru. Would closing our eyes help reduce or get rid of a stutter? I'd say no. I'd still stutter even in a dark room. But that'd be interesting if it turns out that vision does affect stuttering. The reason would be even more fascinating... And yea your English is very good. Probably even better than my own English tbh 😅. I'm guessing you've been doing a lot of self-study even as a kid. That or you're a prodigy when it comes to learning a second language. Either way, you're probably one of those life long learner types who're naturally curious about a lot different things. High IQ types. Why're working as a salesman when you have such high interest in neuroscience and possibly langauges? You could up your salary by a lot no?
