Two stages of bandwidth scaling drives efficient neural coding of natural sounds
Fig 8
Midbrain model decomposition maximizes the modulation entropy of natural sounds.
(A) Spectral and temporal modulation entropy are significantly higher for the midbrain model when compared against Fourier (black; Δf = 30 Hz) and cochlear model (red). (B) The total modulation entropy is highest for the midbrain model when compared against Fourier and cochlear models.
