Multivariate pattern analysis (MVPA) phoneme-specificity maps as a function of signal-to-noise ratio (SNR; in dB). A more negative SNR indicates more additional noise on top of scanner noise attenuated by 25 dB (which was always present, even in the “no noise” condition). Successful MVPA decoding of phoneme identity in ventral premotor cortex (PMC) can only be seen in the “no noise” condition (D), whereas with increasing noise (A–C), decoding is unsuccessful in ventral PMC, but still successful in dorsal PMC and inferior frontal regions (see main text for detailed discussion).
