I'm going to do some science outreach in my son's primary school, and I've received the most wonderful advice:

'when they start speaking, first ask them if it's a story or a question. if it's a story, make sure to cut them off early or they'll talk forever.'

*it works exactly the same with senior academics after presentations*

Make your next discovery using #Rastermap, a visualization method for large-scale neural data. Paper now out: https://www.biorxiv.org/content/10.1101/2023.07.25.550571v1 (click on the gif)

Late #introduction:

I'm a junior group leader in neuroscience. Expertise in calcium imaging, microscopy, data analysis, ephys.

PhD with Rainer Friedrich on computations in adult zebrafish brains and postdoc with Fritjof Helmchen on hippocampal astrocytes. Now I'm interested in hippocampal plasticity.

And Github: https://github.com/PTRRupprecht

I'm here for interesting papers, scientific discussions, methods questions, useful links.

Heading direction maps in the larval zebrafish? 😲
With an anatomical organisation? 🤯

Finally time for a paper tooth!
Check out the final version of our work from the Portugues lab with coauthors Hagar Lavian, You Wu, Fabian Svara and @vilim: https://doi.org/10.1038/s41593-023-01308-5

While imaging (restrained) fish larvae, we observed a peculiar bump of activity propagating clockwise and anti-clockwise over a paired hindbrain nucleus. The bump was moving when the fish was turning left or right!

Welcome to all! ❤️​🐀​
Potential new followers: can we try something out?

- if you're a #Neuroscientist (of any status, yes, undergraduate students can be neuroscientists), could you answer with your neuro 'categories': Experimentalist, Computational, Philosopher, Fly, Human, Rodent, Whale, Tetrodes, Calcium imaging, fMRI, EEG, etc. This is so that I (and possibly others) can put you in a List! I'll share my lists once they have grown enough 😀​

- if you're not a Neuroscientist, this account will probably not follow you, but you are totally free to follow it, and also to tell us about you and any questions you might have about neuroscience!

- if you want to learn about neuroscience, I will try to post beginner-level explanations with the hashtag #NeuroForNewbies. Just an experiment...

One of the hardest lessons I’ve had to learn, but it changed everything.

@albertcardona The renderings of this data set by Amy Sterling on https://FlyWire.ai are beautiful. Others wanting to make their own videos can press one of the "3D viewer" buttons on that site to launch Neuroglancer, and then import its URL into neuVid. See the "Usage with Neuroglancer" section at https://github.com/connectome-neuprint/neuVid. Here's an example video showing the first 6 MBON pairs.

The connectome of the adult female fly brain, Drosophila melanogaster:

A project that started with Davi Bock and Wei Lee developing the TEMCA for the mouse visual cortex in Clay Reid’s lab (Bock et al. 2011 https://www.nature.com/articles/nature09802), then Bock moving to #HHMIJanelia and developing the instrument much further to deliver the #FAFB volume (Zheng et al. 2018 https://www.sciencedirect.com/science/article/pii/S0092867418307876 ), and then the Seung, Murthy and Jefferis labs automatically re-registering, segmenting and annotating the whole volume via #FlyWire and more.

Extraordinary!

On odour landscapes:

"How many compounds do natural odours typically contain? How often are those compounds shared across stimuli? What are the best statistical strategies for discrimination?"

"We quantitatively characterize the odour of 64 vertebrate species (mostly mammals), representing 29 families and 13 orders."

It was a pleasure to host Loic Royer (CZI Biohub) for a Napari-ChatGPT Code Review @hhmijanelia

It was very exciting and I think watching it will give you a nice introduction to the project, but also how to get started using the #ChatGPT API for your own projects:
