This is such a fun meeting. If you are in social neuroscience - you should come. Heck even if you are not - the science is great in general! And a fun mix of animal and human research!

Next time in Canada!

Saykat Ray observed natural behavior in fruit bats 🦇 and found that spatial place cells also encode social information.

These place cells are a cognitive map of the social environment! 😱

🦇 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!

I'm usually not very active here, but good news:
Together with @milliejohnston.bsky.social, our paper on time estimation in #crows got published in @natcomms.nature.com today!
We found crow neurons track time like a stopwatch — without a cortex! 🐦⏱️🧠

A neuronal correlate for time interval estimation in the crow’s telencephalon - Nature Communications

It is unknown how birds estimate time using brains organized differently from mammals. Here, the authors show that neurons in the crow NCL encode duration categories, supporting abstract, cue-independ...

How does a bird remember where it stored its food? @selmaan.bsky.social telling us about neural mechanisms leading to this fascinating behaviour

The new issue is out👉https://www.cell.com/cell/current
⁠
On the cover, Eliav et al. reveal that hippocampal replays in bats flying in very large, naturalistic environments were highly fragmented and short, depicting trajectories covering only a small portion of the environment size.

🚨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

This was a truly collaborative effort! 🧵⬇️

How we’re rebuilding the Weizmann Institute — and our hopes for a better future

Scientific research is at the heart of Israel’s success and has worldwide benefits. Our work will continue despite adversity.

Very, very cool paper from @tamir-eliav.bsky.social and the Ulanovsky lab!

Fragmented replay of very large environments in the hippocampus of bats

Hippocampal replays in bats flying in a 200-m tunnel depict short fragments of long flight trajectories, suggesting constraints on the mechanisms and functions of replay.

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.

How to understand the brain through the lens of natural behaviour?
Here's Nachum's vision on exploring the whole range - from lab experiments to those in the wild.

Join us in this adventure as we uncover what the brain does under the conditions it has evolved in.
