¹Statistics presented for the regression function (linear or log) with the greatest r² value. Positive Θ_M-L values indicate tonotopic axes oriented from dorsolateral to ventromedial compared with dorsal-ventral axis. Positive Θ_A-P values indicate tonotopic axes oriented from dorsoposterior to ventroanterior compared with dorsal-ventral axis. F value used to test significance of the MRA. Abbreviations: A, anterior; L, lateral; M, medial; P, posterior.
