Maybe you did, actually. But what no one could tell is which of the many acoustic features of these vocal sequences female listeners are actually using to make social decisions. (2/6)pic.twitter.com/ZxPAUKpbcq

In this study we took advantage of the natural behaviour that female mice show in response to male courtship songs to ask: what acoustic cues are females using from vocal sequences during goal-directed social behaviour? (3/6)pic.twitter.com/mtL8vtGaSc

It turns out, females are VERY sensitive to disruptions to the songs’ rhythmic regularity; they really dislike irregular, artificially “stuttering” versions courtship songs! (4/6)pic.twitter.com/qXy6RsQ6jB

Disrupting other acoustic features of the songs, such as syllable sequence, or spectrotemporal structure, did not really matter to the females. (5/6)pic.twitter.com/riCtoIUr1H

The take-away? Temporal regularity as a key acoustic cue extracted by mammalian listeners from complex vocal sequences during goal-directed social behaviour. Please check out the paper! https://www.biorxiv.org/content/10.1101/2020.01.28.922773v1 … (6/6)pic.twitter.com/jZU4LedB5g

Aaah ha, congratulations! It clears many hypothesis, and lays foundation for new ones. I also liked the link of temporal regularity as an estimate for breathing pattern/health. Is the centering of the freq. content around 75kHz also critical? Or does it act like a mouseID.

Interesting you should ask this, I'm still collecting data using frequency-shifted songs. Stay tuned :)
