- fMRI signals “up,” but neural metabolism might be going “down.” In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes. rdcu.be/eUPO8 funds @erc.europa.eu #neuroskyence 🧵:
- 1: The BOLD signal is a complex representation of various hemodynamic processes. We used quantitative fMRI to measure all hemodynamic factors contributing to positive and negative BOLD signal changes.
- Reposted by Valentin RiedlWhat started as a spinoff project for Madeleine's PhD became one of the most striking indications that glucose levels play an important role in regulating everyday stress responses. This shows the potential of biosensors to evaluate whether metabolism alters stress reactivity #neuroskyence 🩺
- 📣I’m excited to share our new preprint on how our body’s energy supply shapes everyday stress experiences: 📄𝐇𝐢𝐠𝐡𝐞𝐫 𝐠𝐥𝐮𝐜𝐨𝐬𝐞 𝐥𝐞𝐯𝐞𝐥𝐬 𝐛𝐮𝐟𝐟𝐞𝐫 𝐚𝐠𝐚𝐢𝐧𝐬𝐭 𝐞𝐯𝐞𝐫𝐲𝐝𝐚𝐲 𝐬𝐭𝐫𝐞𝐬𝐬 𝐥𝐨𝐚𝐝 www.biorxiv.org/content/10.6...

- Reposted by Valentin Riedl🧵 What does it take to build a small, scrappy, and successful communication neuroscience lab? Our lab, @gongxuanjun.bsky.social, @rachaelkee.bsky.social, Allyson Snyder, Ziyu Zhao, and I put out heads together to answer this question. Here's what we came up with: link.springer.com/chapter/10.1...

Our MEG + eye tracking study out in Nature Communications study from @thechbh.bsky.social reveals orthographic & semantic previews predicting reading speed www.nature.com/articles/s41...
- Reposted by Valentin RiedlHello! It has been a while, but for the Hector Fellow Academy I created a small project at the interface of neuroscience and music. In short, it is like a neuro-jukebox of projects of friends and colleagues integrating music and art. I thought it would be nice to share here cng-lab.github.io/kiosk

- Reposted by Valentin RiedlYour brain doesn’t just passively track time ⏳ - it structures it. In @Science.org we show that activity in 🧠 memory circuits (LEC) drifts constantly, but makes sharp jumps at key moments, segmenting life into meaningful events. (1/2) 👉 www.science.org/doi/10.1126/...
