Gradients of plasticity
Despite their partially distinctive neural substrates, in typical adults languageand emotion function together as well-integrated communicative systems. Bothpatient and neuroimaging research has furthered our knowledge of the brainorganization underlying language and emotion, yet we know little about howthis organization develops. In this chapter we discuss the initial state of brainorganization for language and emotion, and how these systems develop andchange over developmental time. We address these topics by investigating patternsof language and emotion processing in a population of infants and youngchildren with unilateral perinatal strokes. Our studies reveal gradients of neuralplasticity across language and emotion communicative systems, with relativelygreater neural plasticity for language compared to emotion-processing.
