The time course for cortical areas that have been shown to be involved in speech processing were summated across patients. These areas were Premotor area Brodmann's Area (BA) 6, primary motor area (M1, BA4), middle superior temporal gyrus (mSTG, middle portion of BA22), posterior superior temporal gyrus (pSTG, BA41+42), Broca's Area (BA44+45), Angular gyrus—Wernicke's area (WA, BA39+40) and also posterior middle temporal gyrus (pMTG, posterior part of BA21).
