Inspired by my daughters' books, my first #SpinnerPoster at BAIOSPHERE Medical 2026 turns brain metabolism research into an interactive experience: spin through our project and discover how a contrast-free MRI approach maps changes in the brain’s energy use across tasks and aging. 🧠 lnkd.in/dqCYG5Ra

🧠 Resting-state fMRI is often treated as the gold standard for studying the brain’s intrinsic organization. But is it actually the best way to estimate functional architecture? We tested this directly. 🧵1/8

Samira Epp and Valentin Riedl show that #fMRI blood-flow signals are not a reliable indicator of #BrainEnergy use. Around 40% can oppose neuronal activity, challenging standard interpretations: go.tum.de/211216 #Neuroscience @fau.de 📷G.Castrillon

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 🧵:
Do you ever wish you could just use python to pull together the files and code for running FSL's randomise? Me too! I made this: github.com/jmumford/ran... It will even replace the numbers in the file outputs with contrast names of your choosing (and replace corrp with 1minusp).

Eric Ceballos@cebric.bsky.social · 2y agoHi Bluesky, my first PhD project is finally out! Cells in our bodies can talk to each other in multiple chemical languages, one of the better known being neurotransmitters. Here, we extensively looked at a language that also has its origin in the nervous system — neuropeptides.

Hey Bluesky people! I want to invite you to attend the MRI Together workshop, a free virtual global event dedicated to fostering open, reproducible, and inclusive MR research generously supported by ESMRMB. This event will be held across multiple time zones between 3-6 December 2023.
If you are interested in neural manifolds, dimensionality, brain states, and/or top-down modulation you are gonna like this one! 🧠🙈💫🧪 "Neural manifolds in V1 change with top-down signals from V4 targeting the foveal region" doi.org/10.1016/j.ce... Also enjoy this animation :) #SciArt #neuroskyence
