Participant EC6 cortical modulation tuning map. A, Modulation tuning map for participant EC6. Each MTF is derived from the corresponding STRF. Representative temporal (•) and spectral (■) MTFs are shown. Although MTFs and STRFs contain equivalent information about spectrotemporal processing (except for phase information, which is discarded in MTFs), the overall structure of MTFs is less complex than that of STRFs. As shown, sites in the posterior STG are tuned for high temporal modulations (energy shifted away from the vertical midline) and sites in the anterior STG are tuned for slow temporal modulations and high spectral modulations (energy falling along the vertical midline and shifted upward). LS, Lateral sulcus; STS, superior temporal sulcus; MTG, medial temporal gyrus; CS, central sulcus.
