- The model is supported by evidence from lesion studies and neuroimaging studies.
Language Processing in the Brain
- Syntactic processing is localized to the left inferior frontal gyrus (Broca's area), while semantic processing is localized to the left posterior middle temporal gyrus (Wernicke's area).
