🚨 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

Sparse-to-dense coding transformation between hippocampal areas CA3 and CA1 - Nature
The hippocampus exhibits a CA3-to-CA1 coding transformation that combines fast learning with an efficient, compressed neural code.

Bat brains code space similar to how bird brains code songs, so now 🦇 == 🕊️? 😅 Cool stuff from Shir Maimon and @tamir-eliav.bsky.social

This is Latham Island, a seven-acre speck of land in the Indian Ocean. Here, neuroscientists recorded the brain activity of Egyptian fruit bats as they explored the novel habitat to study the animals’ "internal compass" in the wild, beyond the lab. www.quantamagazine.org/how-animals-...

How does your brain build a sense of direction? New studies into animals’ internal compass could help explain the feeling of getting “turned around”, or even why some of us are so bad at finding our way. @yaseminsaplakoglu.bsky.social reports: www.quantamagazine.org/how-animals-...

Neuroscience projects last several years, and you are usually a bit jaded by the time you wrap it up. Not this one– spending several months on an island in the middle of nowhere, away from all the craziness of the world reminds you how beautiful the world really is. www.youtube.com/watch?v=46sv...

🦇 In a bat colony, neurons build more than a map of space. They code for identity, interactions, and social ties, creating a socio-spatial “map” of the community and social life itself! Read the full story 👉 zurl.co/JInQs 🧪 #HFSPFellowships #sts #HFSPscience

🚨Very happy that my PhD work is now out in @nature.com! We discovered that evolution, by acting in the midbrain, shifted the threshold to escape in Peromyscus mice, to fine-tune defensive strategies in different environments www.nature.com/articles/s41... This was a truly collaborative effort! 🧵⬇️

Happy 99th birthday to the man who gave voice to the wild. 🎉 Sir David Attenborough, thank you for a lifetime dedicated to the natural world, and for sharing its story with wisdom, wonder, and grace. You've inspired generations to fall in love with nature.
This photograph captures Sir David Attenborough seated outdoors on the rugged terrain of Skomer Island. Behind him, the ocean and coastal cliffs form a scenic backdrop under a clear sky. Sir David, dressed in a khaki jacket and light trousers, looks towards the camera with a gentle expression, exuding a sense of warmth, calm, and wisdom. Around him, puffins can be seen flying and perched on the rocky ground, illuminated in rays of golden sunlight as the sun sets behind the cliffs.
