This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

I use the restart hotkey in RStudio and I see the restart button in Positron, but what I really mean is that instead of just "source", there would be a "restart R + source" button - and I don't see this in Positron either. Maybe it's just me who misses this :)

Restart R and source script button · Issue #15854 · rstudio/rstudio Problem Statement When analyzing data, frequently restarting R and sourcing a script is a good idea. This can be done in 2 steps while this is a very-very frequent thing to do. Many times sourcing ...

I think, for the same reason, IDEs should have a button for "Restart R session and source script". Do you think that is a good idea? I posted this feature request for RStudio, maybe it can get some traction here: github.com/rstudio/rstu...

That would be great!

Slide titled: "Assumptions of the model and model checking" with a scatterplot with axes how much people should worry vs how much people do worry.

this slide is from a colleague's introductory stats course, I think it fits many statisticians' experiences

Image of brain networks in a group average and individual LPFC. Individuals show: 1) smaller FP network 2) more interdigitation 3) conserved motifs 4) idiosyncratic features This was validated with task and rest fMRI

The lateral prefrontal cortex 🧠— which we think of as critical for goal driven behavior + is a target for psychiatric treatments— is fundamentally different in individuals relative to the group averages we’ve often studied.

You also seem to imply, but definitely 🐇 AND 💤. For me: Rr for exploring literature via citation graphs, Zz mostly for citation. I'm trying to use Zz for storing and keeping track of papers but I'm not completely satisfied. I'd put Obsidian in the stack as well, as a third leg.

I just read the following quote from Mel Robbins, presented as if it were good advice. It makes me shudder:

“You’ll never feel ready to change your life. One day you just get tired of your own excuses and force yourself to do it.”

There is so much badness in that single sentence.

Our new paper - the first peer-reviewed brain and phenomenological examination of 5-MeO-DMT is out in Neuro of Consciousness.

TLDR: We tested whether ‘the mount Everest’ of psychedelics could induce a complete state of consciousness deconstruction while preserving awareness. 1/n

Excited to share our latest paper!

We argue that in MS, the primary immune attack isn’t on myelin or myelinated axons — but on the ion & water homeostasis machinery in astrocyte endfeet.

A short thread on this new perspective

Excerpt from a public letter Roald Dahl wrote encouraging people to vaccinate their children. Olivia, my eldest daughter, caught measles when she was seven years old. As the illness took its usual course I can remember reading to her often in bed and not feeling particularly alarmed about it. Then one morning, when she was well on the road to recovery, I was sitting on her bed showing her how to fashion little animals out of coloured pipe-cleaners, and when it came to her turn to make one herself, I noticed that her fingers and her mind were not working together and she couldn’t do anything. “Are you feeling all right?” I asked her. “I feel all sleepy,” she said. In an hour, she was unconscious. In twelve hours she was dead. The measles had turned into a terrible thing called measles encephalitis and there was nothing the doctors could do to save her. That was twenty-four years ago in 1962, but even now, if a child with measles happens to develop the same deadly reaction from measles as Olivia did, there would still be nothing the doctors could do to help her. On the other hand, there is today something that parents can do to make sure that this sort of tragedy does not happen to a child of theirs. They can insist that their child is immunized against measles. I was unable to do that for Olivia in 1962 because in those days a reliable measles vaccine had not been discovered. Today a good and safe vaccine is available to every family and all you have to do is to ask your doctor to administer it.

The measles outbreak in Texas is reminding me of the public letter Roald Dahl wrote about losing his daughter to measles in 1962, just before the vaccine was publicly available.

Then you probably do :) I very often need to work with quite small n.

No, I mean more observations (eg. subjects an/or trials).

If you treat it as category, you probably need more data. As a cont. factor eg. it can be just one linear term, for cat., it's ncats-1 terms. If you add it to rfx n of parameters further explodes. This is my hunch of what could be happening, but ofc depends on the particular error you get :)

New paper!   People often do not remember information they just searched for (link.springer.com/article/10.3...).
