Consciousness: What is the role of prefrontal cortex?

Is the left inferior frontal cortex (LIFC) a single functional region, or can it be subdivided into distinct areas that contribute differently to word processing? Here we used transcranial magnetic stimulation (TMS) to investigate anterior and posterior LIFC when the meaning and sound of words were being processed.}, author={Katsuki Nakamura and Ryuta Kawashima and Kengo Ito and Motoaki Sugiura .Here, we provide converging evidence from computational modeling and two functional magnetic resonance imaging experiments that indicated a key role of inferior .
