The paper shows that temporal envelope steepness is mapped orthogonally to the tonotopic axis in mouse auditory cortex, forming a two-dimensional map for sound processing.

The paper maps reciprocal connections between the secondary auditory cortical field (A2) and the lateral amygdala (La) in mice, showing dense innervation and retrograde labeling in La after A2 injection, while other auditory fields show minimal connections.

The paper shows that thalamocortical projections from the medial geniculate body to A2 establish tonotopy in the secondary auditory field, with greater divergence than to A1.
