I agree with everything you said! I think that neurological (in developmental stuttering) mainly refers to inhibition, compensation (reorganisation of function to the right hemisphere), and error responses (as per the research *"The Role of Sensory Feedback in Developmental Stuttering"*). So as [Alm ](https://www.youtube.com/watch?v=HaqT7cZdWSw&ab_channel=SchneiderSpeech)(PhD) says, there isn't any neurological brain damage or anything. I also propose that, when people who stutter when speaking alone, it doesn't have the implication that it's more neurological (than when they don't stutter when alone), just that they also encounter a kind of trigger mechanism (or, they activate this emotional-monitoring-response mechanism) when they stutter when alone. So basically **defeatism** triggering a freeze response
