Hypothesized Neural Correlates of DIVA
The results of lesion / aphasia studies; microstimulation studies in human patients; MEG, PET,and fMRI imaging studies; and single cell recordings in animals provide a basis for hypothesizing neural correlates for the central components of the DIVA model. The figure below shows our current hypotheses for brain regions involved in the stages of speech production addressed by DIVA.
