Participant EC6 cortical STRF map. A, STRF map for participant EC6 (STRFs calculated with MID analysis). STG STRFs showed clear contiguous excitatory and inhibitory regions and structure characteristic of STRFs found in other regions. Representative temporal STRFs (•, tuned to quick onsets or offsets), and spectral STRFs (■, tuned to constant sound energy that fluctuates across frequency), are shown. LS, Lateral sulcus; STS, superior temporal sulcus; MTG, medial temporal gyrus; CS, central sulcus.
