🚨New pre-print! How do we form concept representations across vision and language? Using similarity judgements of natural scene images & sentence captions, we show that concepts are formed as structured representations reflecting stable, relational properties of the world.🧵

1/13 Heavily updated preprint! arxiv.org/abs/2209.11737 We show that the contextual information encoded in Large Language Models (LLMs) is beneficial for modelling the complex visual information extracted by the brain from natural scenes. 🧵

The human brain extracts complex information from visual inputs, including objects, their spatial and semantic interrelations, and their interactions with the environment. However, a quantitative...

sourcherries.github.io/blog/… Want to know why #numpy masked arrays are awesome for #DataScience and research?

Carl Gaspar - Why masked arrays are useful for data science. Part 1

Ever needed to compare lots of variables and missing data made things super slow?

We are seeking out ideas for future Generative Adversarial Collaborations at CCN! Which challenges and controversies would you like to see discussed, and who should be involved? Let us know your ideas, even if you are not planning to submit a GAC. app.fillout.com/t/eAAUdbJ3S7…

Future Generative Adversarial Collaborations

Made with Fillout, the best way to make forms, surveys and quizzes your audience will answer.

Fusing #MEG and #fMRI data, we observe the evolution from acoustic to semantically dominated representations in brain responses to naturalistic sounds: tandfonline.com/doi/full/10.…

Cochlea to categories: The spatiotemporal dynamics of semantic auditory representations

How does the auditory system categorize natural sounds? Here we apply multimodal neuroimaging to illustrate the progression from acoustic to semantically dominated representations. Combining magnet...

Prof. @DuprasCharles presenting at #GDO2022 on epigenetic discrimination: "The testing purpose problem - epigenetic testing can provide genetic information, thus providing indirect genetic testing. How should policies consider this?"

Replying to @KordingLab @Quendera @CogCompNeuro
feel free to drop a page break in there after the author list. content (abstract, intro, methods, results, discussion) should be 2 pages, but this is not counting title, author list, acknowledgements, and references!

IT IS NOT A PREPRINT ANYMORE! You find the published paper here:cell.com/current-biology/ful… Huge THANKS to @AlexChatburn @IanCharest George Balanos and of course to @BStaresina. We would also like to thank the reviewers who gave valuable comments that massively improved the paper!

Sleep spindles track cortical learning patterns for memory consolidation

Petzka et al. provide evidence that post-learning sleep spindles track learning-related cortical networks and thereby facilitate memory consolidation.

🔔Check out our new preprint! We show that sleep spindles track cortical learning patterns for memory consolidation. Great teamwork with @AlexChatburn @IanCharest George Balanos and @BStaresina. biorxiv.org/content/10.1101/…

Sleep spindles track cortical learning patterns for memory consolidation

Memory consolidation, the transformation of labile memory traces into stable long-term representations, is facilitated by post-learning sleep. Computational and biophysical models suggest that sleep...
