In summary,domain-general learning mechanisms involving striatal and MTL circuits are also recruited for speech and language learning. Corticostriatal systems are involved when adults learn speech sequences for articulation and when complex regularities inauditory sequences must be extracted. MTL circuits are relevant for learning arbitrary and explicit however, nosingle speech or language behaviour is associated with corticostriatalor MTL circuitsalone; instead
there are inter actions between these learning systems as language is learned
