I couldn't find a tool to plot different #neuroimaging data in one consistent style, so I made one! Meet yabplot (yet another brain plot) - a #Python package for (sub)cortex & tracts.🧠
- Simple API
- Built-in atlases
- Custom atlas support

neuromapr 0.2.1 has been accepted and published on CRAN!
Very excited to get this out to users in the simplest way possible, and hope the #rstats #neuroimaging community finds it useful!

The Neuromodulatory Subcortical Systems PIA within @istaart.bsky.social is requesting nominations for the best paper of 2025 on neuromodulatory subcortical systems in Alzheimer's disease!! ISTAART members: promote the work of your colleagues (or yourself) here: alz.surveymonkey.com/r/Publicatio...
Nine subcortical/cerebellar atlases included in the subcortex_visualization Python package (and subcortexVisualizationR package in R). The atlases are depicted in two-dimensional vector graphic format.
The extended version of my thesis procrastination project/subcortex visualization package is out now in both Python and R, now that I’ve graduated 🤠 This figure shows the 9 atlases included (and counting)!

Excited to share our new preprint! We explore the link between the locus coeruleus (LC) and arousal for astrocytes, pyramidal cells, interneurons in the hippocampus. A fantastic collaboration with @sianduss.bsky.social @bohaceklab.bsky.social, and many others: www.biorxiv.org/content/10.6... 1/5
Reposting this postdoc position, we are still reviewing applications. I will also be at Human Amyloid Imaging from 1/12 till 1/15 and happy to meet.
Thrilled this is out, led by former PD Cameron Ogg (now with her own lab at @rhodescollege.bsky.social!). It was a driven by a desire to see, in real-time, how LC activity/NE release influences downstream targets in behaving animals. SO hard to do, but Cameron did it! www.cell.com/cell-reports...
BOLD signal changes can oppose oxygen metabolism across the human cortex, Nature Neuroscience
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.

#neuroskyence 🧵:
This new ERC study uses an overlapping set of human 🧠 donors as our just dropped locus coeruleus preprint. Availability of data from both regions in the same donor facilitates our current efforts to analyze molecular signaling across the circuit, which is highly vulnerable in Alzheimer's disease.
Postdoc position: our team is looking for a postdoctoral colleague interested in developing and testing theories of brainstem function in AD using fMRI/PET. The Martinos Center / MGH in Boston is a superb place to work. Reach out if you have any questions. Come and join us! 🎉🔵

Academic mentoring across generations: earlier this week, I heard my mentor commenting on writing and how to convey findings clearly, and realized that I now mentor in the exact same way. When my student received compliments for clarity in writing from a co-author, I was immensely proud & grateful.
