Feedback interconnections are widespread in the brain; yet clear explanations for most of them are currently lacking. Carmen Amo Alonso and John Doyle explore current experimental evidence on the relationship between the auditory and motor parts of the brain during speech perception and production. These models provide a plausible explanation for how the structure of language, as described in the Parallel Architecture, is implemented in the brain. Together, they provide a plausible account for how the Parallel Architecture of language originates as a result of functional constrains in the sensorimotor system. They compare the brain’s implementation of the language capacity with other cognitive capacities, such as vision or motor planning and control, which also have massive internal feedbacks that our new theory explains for the first time.
