Document Summary
It can be helpful for some families and pws to thi(cid:374)k of stutteri(cid:374)g as a (cid:862)(cid:373)edi(cid:272)al(cid:863) disorder (not a psychological or voluntary disorder) A neuroanatomy primer: frontal lobe, pee(cid:272)h produ(cid:272)tio(cid:374) (cid:894)bro(cid:272)a"s area(cid:895, decision making, reasoning, personality, structures, primary motor cortex, located on the precentral gyrus. All of the interconnections; axons of the neurons: axons transmit information from the cell body to other parts of the brain, gyri ridges on the brain. Inferior frontal gyrus: part of bro(cid:272)a"s area, sulcus the valleys, superior temporal sulcus, wer(cid:374)i(cid:272)ke"s area, auditory cortex. Structural imaging techniques: looks at the shape and size of brain structures, e. g. , ct, mri, dti, lets you determine there is any damage. Functional imaging techniques: electrical and chemical changes in the brain, e. g. , pet, fmri, lets you know if that part of the brain still works. Structure of brain of those who stutter: gray matter, decreased gray matter density in the left inferior frontal gyrus, fewer neuronal cell bodies.
