Quantifying rhythmic and arrhythmic brain activity is a hot 🥵 topic. But how independent are the two components from one another? 🤔 In my latest work with @smfleming.bsky.social & @matlandry.bsky.social, I explore the relationship between the two.

🧠 New preprint: Why do deep neural networks predict brain responses so well?
We find a striking dissociation: it’s not shared object recognition. Alignment is driven by sensitivity to texture-like local statistics.

Very excited to share this work (it’s been a long time in the making). Here we show that both top-down 📖 and bottom-up ‼️attention modulate 🧠alpha-band activity, which partially explains the interference between the two attention systems when oriented 👀to opposite spatial locations.
