Let's all discuss this research about dopamine: "Dopamine reward prediction-error signalling: a two-component response" (2017) Research [link ](https://pmc.ncbi.nlm.nih.gov/articles/PMC5549862/)([PDF ](https://pmc.ncbi.nlm.nih.gov/articles/PMC5549862/pdf/nihms884725.pdf)version). Also see [this](https://www.sciencedirect.com/science/article/pii/S1053811920302536): "Dopaminergic neurons first signal detection, then reward prediction error". **Question**: IYO, How do dopamine and prediction errors relate to stuttering development (particularly trigger formation)? >Environmental stimuli and objects, including rewards, are often processed sequentially in the brain. Recent work suggests that the phasic dopamine reward prediction-error response follows a similar sequential pattern. An initial brief, unselective and highly sensitive increase in activity unspecifically detects a wide range of environmental stimuli, then quickly evolves into the main response component, which reflects subjective reward value and utility. This temporal evolution allows the dopamine reward prediction-error signal to optimally combine speed and accuracy.
