Orthogonal representation of sound dimensions in the primate midbrain

Natural sounds are characterised by their spectral content and the modulation of energy over time. Using fMRI in awake macaques, we report topographical representations of these spectral and temporal dimensions in a single structure, the inferior colliculus, the principal auditory nucleus in the mid...

description Natural sounds are characterised by their spectral content and the modulation of energy over time. Using fMRI in awake macaques, we report topographical representations of these spectral and temporal dimensions in a single structure, the inferior colliculus, the principal auditory nucleus in the midbrain. These representations are organised as a map with two approximately perpendicular axes: one representing increasing temporal rate and the other increasing spectral frequency.
