iiinova — where your digital self keeps evolving

Here's your brain when you have not listened to an album for too long. You can almost reproduce this with plot_brain(load_example_image("pain_response"), cmap="Midnight2")! Tagging inspiration: www.blakerobertmills.com github.com/karthik/wesa... colorbrewer2.org pni-lab.github.io/quickbrain/

No public funding can match Taylor's pockets when it comes to design. Why reinvent the wheel? We've K-mean clustered your favourite albums, then cherry picked. It’s as simple as scale_color(era.brewer("Lover1", n=5)) in R, or whatever incantation python uses. And it looks better than viridis 🙄

Good scientist, terrible designer? We feel you. Inspired by MetBrewer, the palette chooser for the connoisseurs, @sandra-neuro.bsky.social and I present EraBrewer: great looking colours for us Swifties! github.com/mathias-sm/E... cran.r-project.org/web/packages...

During passive shape perception in MEG in adults, we find dissociation in space and time between two models of geometric shape perception. Early visual activity resembles bottom-up perception as embodied by a CNN. Subsequent parieto-frontal activity is best explained by geometric features.

In a simple fMRI visual localiser, with no task, comparing single shapes to other single visual categories (faces, tools, houses) elicits an under-activation of the visual pathways. It also elicits an over-activation of (right) IPS in adults and children, close to typical math-responsive areas.

First, the behaviour: when faced with finding an intruder within quadrilaterals, the accuracy and response time of humans vary a lot and are well predicted by the exact geometric features of the shapes—more so than by their visual features embodied in a neural network.

Excited to see this Version Of Record of my work out in @elife.bsky.social! elifesciences.org/articles/106... We investigate the mental representation of geometric shapes in adults and children using fMRI and MEG. Each figure has a video of me explaining the figure: go and read it, or read below.

Come join us at #SfN25 for the minisymposium "Cognitive Maps in the Prefrontal Cortex"! Saturday, Nov 15, 2:00-4:30pm, Room SDCC 6CF www.abstractsonline.com/pp8/#!/21171... We will explore how the PFC represents structured relationships across species and how this supports flexible behavior.

Second night of #pint25 was really fun 🧠🍻 @nadinedijkstra.bsky.social and @matanmazor.bsky.social gave spectacular talks and we couldn't stop the audience from asking questions—nor did we want to. Can’t wait for tonight, grab your ticket and join us!

Pr. Mehrnoosh Sadrzadeh explaining "How Can Large Language Models Become More Human?" to a captivated audience. #pint25 has started; it's great fun to see it come together! Join our "Beautiful Mind" theme at The George IV in Chiswick, or any other fascinating topics featured in pintofscience.co.uk
