Functional partitioning of sentence processing and emotional prosody in the right perisylvian cortex after perinatal stroke.

ABSTRACT: In healthy adults different language abilities-sentence processing versus emotional prosody-are supported by the left (LH) versus the right hemisphere (RH), respectively. However, after LH stroke in infancy, RH regions often support both abilities with normal outcomes. This finding raises an important question: How does the functional map of RH regions change to support both emotional prosody and also typically left-lateralized language functions after an early LH stroke? Does sentence processing simply become reflected into RH frontotemporal regions and overlap with emotional prosody processing? Or do these functions overlap less than would be expected with simple mirroring? In the current work we used task fMRI to examine precisely how sentence processing and emotional prosody processing
