1/ The world's songbirds sing in just 8 basic sounds. And where a bird lives decides which ones it uses. My first PhD paper is out now in @science.org (www.science.org/doi/10.1126/science.aee6239) Here is what we found:

🚨 New paper in @nature.com We asked why two hippocampal areas with very different anatomy, CA3 and CA1, often seem to code space so similarly? By recording bats flying up to 200m, we found that the difference was hidden by scale! www.nature.com/articles/s41... 🧵 1/11

out now in Science: @loganjames.bsky.social collected pairs of sounds in 16 species where we *know* which sound is more attractive (to that species) he played them to ppl on themusiclab.org, asking, in each pair, which was nicer. humans agreed w other animals doi.org/10.1126/science.aea1202

Mehr5,7,8Many animals produce courtship sounds, and receivers prefersome sounds over others. 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. These results are consistentwith theories arguing that biases in processing sculpt acousticpreferences, and they confirm Darwin’s century-old hunchabout the conservation of aesthetics in nature

We had a lot of fun doing these experiments! Theta sweeps in MEC and internal direction signals in parasubiculum track moving objects during pursuit and reverse during backward movement. Simultaneously recorded HD cells in other areas remain locked to head direction across behaviors:

The hippocampal map has its own attentional control signal! Our new study reveals that theta #sweeps can be instantly biased towards behaviourally relevant locations. See 📹 in post 4/6 and preprint here 👉 www.biorxiv.org/content/10.6... 🧵(1/6)
biorxiv.org
Attention-like regulation of theta sweeps in the brain's spatial navigation circuit
Spatial attention supports navigation by prioritizing information from selected locations. A candidate neural mechanism is provided by theta-paced sweeps in grid- and place-cell population activity, which sample nearby space in a left-right-alternating pattern coordinated by parasubicular direction signals. During exploration, this alternation promotes uniform spatial coverage, but whether sweeps can be flexibly tuned to locations of particular interest remains unclear. Using large-scale Neuropixels recordings in freely-behaving rats, we show that sweeps and direction signals are rapidly and dynamically modulated: they track moving targets during pursuit, precede orienting responses during immobility, and reverse during backward locomotion — without prior spatial learning. Similar modulation occurs during REM sleep. Canonical head-direction signals remain head-aligned. These findings identify sweeps as a flexible, attention-like mechanism for selectively sampling allocentric cognitive maps. ### Competing Interest Statement The authors have declared no competing interest.
