I was particularly excited to see elaboration of the superorbital sulcus seals - this region appears to overlap with vocal motor cortex, and seals have apparently much greater vocal production plasticity than sea lions. Also interesting changes in somatomotor cortex possibly related to locomotion.

Obviously a fun study, but rhythmicity is more the rule than the exception in repetitive vertebrate vocalizations. The rhythm typically comes from respiratory cycles and peripheral effector resonance, not cortical neural control.

I always assumed that brain function had to line up with cytoarchitectonics. It turns out I was wrong. Human cortex, especially PFC, is tiled by chains of functional patches that subdivide and interlink architectonic areas into parallel processing streams. www.biorxiv.org/content/10.6...

Shared ancestry and convergentevolution may generate similarities in preference across speciesand underlie Darwin’s conjecture that some animals “havenearly the same taste for the beautiful as we have.” In this study,we show that humans share acoustic preferences with a rangeof animals, that the strength of human preferences correlateswith that in other animals, and that humans respond fasterwhen in agreement with animals. Furthermore, we foundgreatest agreement in preference for adorned, ancestral, andlower-frequency sounds. humans’ music listening experiencewas associated with preferences.
