Posting on behalf of the semi-X-less @sNeuroble ! So excited to share: What started with fMRI effect size benchmarks ended up showing that conventional study planning detects ~half of expected brain effects, suggesting more distributed processes than the lit shows🧠

On another exciting note — I’m also on the job market! Always looking forward to discussing potential opportunities :) stop by my poster 1:45-3:45PM and the 6PM poster reception to chat!

Spatial heterogeneity of CSF related-noise in fMRI: why it matters and what we can do about it. My work at #OHBM2025 provides evidence for taking a region-specific approach when isolating CSF artifact in the subcortex. Swing by #P1358 on Fri/Sat to discuss!

@PessoaBrain @sNeuroble Absolutely!!! I’d love to discuss the potential implications for the PAG 🧠

Had a great time presenting my work at #CNS2025. A huge thank you to my advisor @sNeuroble for helping me bring this project to life. Incredibly excited to see how well received our poster was and I can't wait to share new developments at #OHBM this June! #fMRI #CSF

Improving fMRI signal quality starts with better noise modeling. My project at #CNS2025 shows how localized region-specific CSF correction may better isolate neural activity and increase sensitivity in the subcortex. Come by my poster #D138 to learn more! (Mon. 8:00-10:00AM) 🧠

Really fantastic and innovative work led by my amazing NeuroPRISM lab colleague and good friend. Congrats @ShearerHallee!

Curious if movie-watching can improve the reliability of FC from a certain brain region? Check out our Shiny App vanderlab.shinyapps.io/movie_stuff/ to explore the results from our ROI-based comparison of the test-retest reliability of FC between movie-watching and resting-state fMRI.

@PessoaBrain There's rodent work pointing to the BNST's involvement in safety learning/processing. Following exposure to inescapable tail shocks, safety signals decrease Fos immunoreactivity in the BNST and freezing behavior.

In humans the ventromedial PFC is discussed as involved in 𝘀𝗮𝗳𝗲𝘁𝘆-𝗿𝗲𝗹𝗮𝘁𝗲𝗱 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴, among other functions. Other brain regions come to mind? The posterior cingulate also pops up.
