Having a stuttering problem as a boy, I had to consciously engage this stuff in order to control stuttering but being profoundly deaf, it wasn’t always easy.
So this is engaged all of the time. I have SOME idea what I expect to see as to what part of the brain is is as I’ve studied this stuff BUT — I look forward to being sure — and I hope I’m wrong because that’s even more interesting!
Clicking now – good find!
Oh this is fantastic – I’d been looking for this and didn’t know why I couldn’t find it. I knew it was around there but it was never clear EXACTLY…“Publishing in the journal PLOS Biology online Feb. 3, results of the new investigation revealed that while three cortical regions were primarily involved in correcting errors in speech, including the superior temporal gyrus and supramarginal gyrus, only one, the dorsal precentral gyrus, dominated when delays in speech, meant to signify feedback errors, were maximized. These brief feedback delays ranged from 0 milliseconds to over 200 milliseconds and were designed to mimic real-life slurring of speech.”

Playing the piano is from this area too. This is the area of “voluntary controlled movements”.
This is where intention seems to begin.
“Primary Motor Cortex: lies in the “precentral gyrus” in the frontal lobe. Controls movement of the opposite side of the body. (Blumenfeld, 28) A vertical strip of cortical tissue in the frontal lobes that lies just in front of the furrow that separates the frontal lobe from the parietal lobe. When you decide to move your hand, the chain of events leading to its movements originates in the motor cortex. (Ramachandran, 44) A ‘higher’ brain region that issues voluntary movement commands. (RamachandranTTB, 18) Specialized in producing voluntary skilled movements, like playing a piano or combing your hair. (Hawkins, 113) Concerned mainly with simple movements like wiggling your finger or smacking your lips. (Ramachandran, 44) Also referred to as the ‘motor cortex,’ ‘primary motor area,’ ‘Brodmann Area 4,’ and ‘M1.’”
