FIG. 1.
New speech network model shows parallel inputs to Wernicke’s area (pSTG). A: Classic models postulate the dominant inputs to pSTG are from Heschl’s gyrus (red arrow). B: New speech network models show posterior superior temporal gyrus receives parallel input from other sources, potentially lowering the risk of aphasia from resection of the primary auditory cortex (blue arrow). HG = Heschl’s gyrus; PP = planum polare; PT = planum temporale; STG = superior temporal gyrus.
