Title: A gradient perspective on the neural basis of semantic cognition
Abstract: Since we have a wealth of information about any given concept, our store of knowledge is not sufficient for successful semantic cognition; we also need mechanisms that can steer the information we retrieve so it suits the context or our current goals. Evidence from neuropsychology, fMRI and TMS suggests a semantic control network, distinct from domain-general executive control, supports this function. The semantic control network is juxtaposed between default mode network and multiple-demand regions in the left hemisphere, suggesting that the large-scale organisation of flexible semantic cognition can be understood in terms of cortical gradients that capture systematic functional transitions that are repeated in temporal, parietal and frontal cortex.
