Fun comparison but I don’t think it is meaningful. MoCA score is only a “proxy” (and not a good one I should add) for cognitive abilities of a “human”, only because of the data we have on how it varies across healthy and impaired population. That an AI scores 25 tells me little about it.

Very true!
Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.

There is a lot we can learn with one image! Check the channels separated
1 - Astrocytes being part of the blood-brain-barrier, look at this vessel shape!
2 - Red blood cells lacking nuclei can be very, very tiny!
3 - Some of the green cells inside the blood vessels are macrophages, not microglia!

Why probability probably doesn’t exist (but it is useful to act like it does)
All of statistics and much of science depends on probability — an astonishing achievement, considering no one’s really sure what it is.

I used to think that art and science are two disjoint disciplines until I came across @daniellebeckman.bsky.social’s work. Truly mesmerizing.
Having a difficult day, but I'm glad to have microscopy to inspire me and hopefully inspire others as well. 💔

A great example of reporting negative results, which is as important as positive ones.
📢 New research! Does the EEG biomarker of central serotonergic activity, LDAEP, link to suicidality in Major Depressive Disorder (MDD)? 🧠 Our meta-analysis and independent cohort study reveal key findings. Dive in! 🧵 #depression
