This is pretty cool - reptile found that can sense low frequency sound with the saccule: doi.org/10.1016/j.cub.2024.09.
(I'll edit with a direct PDF link in a sec)

Hearing evolved in fishes, where the swim bladder as a big resonant cavity reached out to touch the vestibular organ and kinda vibrate it. That is only good for low frequencies, so to some degree the history of the evolution of audition has been a quest for higher frequencies - thinning out a tympanic membrane, the evolution of the inner ear by stealing jawbones, the enlargement of the brain case to close off the middle ears (our eustachian tubes are vestigial remnants of what used to be an "open passageway" from ear to ear).

Sound is a veridical readout of the matter that produces it, so different frequency ranges contain different kinds of information, and small things including textures and material composition are only audible with higher frequency ranges. Low freqs are important too, but especially with the transition to land, needing to handle the impedance mismatch between fluid filled bodies and open air makes an organ that can hear a wide range of frequencies challenging.

So the cochlea gets all the attention as the auditory organ because its one of the most remarkably precise and Scientifically Magical organs out there, but the vestibular system is cool too. It's basically a bag of saltwater and rocks and when you jangle your head around the rocks touch little hair cells and tell you you're moving.

Because of its torrid history the auditory system is sort of a clusterfuck, but these researchers found direct projections from the Saccule through to the auditory midbrain. They're sensitive to vibration (through a surface), not sound (through the air), but still go to auditory system, so while we have no idea what the perceptual reality is like, i dont think it is unfair to say that the geckos "hear vibration."

📢 THIS FRIDAY📢

Call to #AuditoryNeuroscience folks, especially ECRs, to join us for our next collaborative review run w/ #CRNEUR

🗓️ July 28, 15:00 UTC
🔗Register: bit.ly/reviewtogether-July28
📰#preprint: doi.org/10.1101/2023.0

ZoomWelcome! You are invited to join a meeting: PREreview and CRNEUR Community-Based Review Pilot 3. After registering, you will receive a confirmation email about joining the meeting.PREreview and Current Research in Neurobiology (CRNEUR) are collaborating to host 5 open, collaborative, and interactive review events styled after PREreview Live-streamed Preprint Journal Clubs. These are topic-centered, interactive online calls in which participants are guided to provide constructive feedback to a preprint. We are hosting the third event of this pilot on July 28th at 15:00 UTC - check your local time here: https://www.timeanddate.com/worldclock/converter.html?iso=20230728T150000&p1=1440. Together we’ll be discussing this preprint: “A sparse code for natural sound context in auditory cortex” by Mateo López Espejo and Stephen V. David - bioRxiv: https://doi.org/10.1101/2023.06.14.544866 Please ensure you read the preprint prior to the event. The event will last 90 minutes and will yield a review based on the collaborative notes participants will be jointly taking during the call. The review will be shared and published on PREreview.org under CC BY 4.0 licence. Participants will have the option to sign the final review using their real name (via their ORCID iD) or via a pseudonym provided by the PREreview account. The CRNEUR editorial team will consider the review as an addition to their standard journal workflow protocol. For more information please read our blog post: https://content.prereview.org/prereview-and-crneur-pilot/ or email us at community@prereview.org. Feel free to share this opportunity with colleagues.
