Listeners are constantly trying to predict what the speaker will say next. We concurrently measured the electrophysiological and haemodynamic correlates of syntactic pre-activation, investigating when and where the brain processes speech melody cues to upcoming word order structure. Pre-activation of syntactic structure was reflected in a left-lateralised pre-activation negativity (PrAN), which was subserved by Broca's area in the left inferior frontal gyrus, as well as the contiguous left anterior insula.
听众一直在试图预测说话者接下来会说什么。我们同时测量了句法前激活的电生理和血液动力学相关物，研究大脑何时何地处理言语旋律线索以预测后续的词序结构。句法结构的前激活反映在左侧的前激活负波 (PrAN) 中，该波由左额下回的布洛卡区以及相邻的左前脑岛共同作用。
