The paper identifies noncanonical auditory pathways in mice that bypass primary auditory cortex and directly activate secondary auditory cortex layers, enabling parallel sensory processing.

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 identifies the orbitofrontal cortex as a source of predictive signals that suppress irrelevant auditory inputs through inhibitory neurons in the primary auditory cortex.

The paper evaluates the accuracy of stereotaxic coordinates for targeting functional cortical areas in mice by comparing atlas-based coordinates with functionally identified auditory cortices.

The paper investigates how the mouse secondary auditory cortex integrates multi-frequency sounds, showing that SOM interneurons broaden the temporal window for harmonic integration.

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.
