Twitching during REM sleep is important for honing the sensorimotor system during development in humans and other animals. But why do adults twitch during sleep?

Hi Greg,
This looks very interesting.
Would you mind sending me the pdf at mark-Blumberg@uiowa.edu?
Until someone proves otherwise, I remain of the opinion that twitches are distinctly non-cortical. That was shown long ago in adults by Pompeiano’s group
and I have not seen any reason yet to doubt it.
New paper (with lots of cute animal videos!)
Ever watch your dog "run" while asleep and wonder what’s going on in their brain? In Current Bio we suggest that those twitches aren't just leaky dreams—they’re a vital maintenance system for the most precise movements

Some brags land differently than others.
Congratulations to @antbergel.bsky.social and Paul-Antoine Libourel on their new paper. It was a pleasure being a part of the effort. I also enjoyed reading this article about the new findings: www.thetransmitter.org/sleep/snoozi...
⚠️ New paper alert and what a way to end 2025! 🎉
Happy to share our story “Sleep-dependent infraslow rhythms are evolutionarily conserved across reptiles and mammals.” published today in Nature Neuroscience.
Sleeping dragons 🦎 and functional ultrasound!

This is a wonderful thread by @kohngregory.bsky.social! Read it carefully, follow the links, and spread it around. More scientists, including neuroscientists, will think better if they take the time to understand these important issues.
Thanks for this great thread! These ideas cannot be communicated often enough. It seems that every generation seems to invent new reasons to invoke innateness. Today, many neuroscientists think that claiming innateness for their preferred phenomenon somehow makes their work more important. Sad...
The deadline for our open-area senior search is approaching. If you're looking for a new academic home and, perhaps, the security of a hard-money position, please consider applying.
If you have any questions about this position or the one in clinical science, please don't hesitate to reach out to me. We're a growing, interdisciplinary, closely-knit, and supportive department. And we're looking for exceptional junior and senior scientists to join us.
The ad for the tenure-track Clinical Science position is live. Please spread it around!

"chronic venous insufficiency." So that's what they're calling _____ these days.
Two faculty positions in my department this year. Please spread the word! And don't hesitate to reach out if you want to learn more.
"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?" "Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."
I think a lot about what Carl Sagan said in one of his final interviews.
The National Institutes of Health, the largest funder of biomedical research in the world, has fired 1,300 employees and cancelled more than $2 billion in federal research grants. https://cbsn.ws/4daiCrv
Our cover this week.
Geez, if only the University of Iowa were among those mentioned in this article. Is it really that difficult? Even Nebraska is ahead of us. Nebraska!
From The Atlantic: “The Trump administration is manipulating government-sponsored research to get the answers it wants.”
Who remembers Lysenko?
We are all Harvard now. (gulp)
Kerr is such a class act.
Well, at least we know something horrifies her. It just ain't the people around her.
I'm ashamed of the silence from campus leaders across the country as our international students are terrorized by threats, intimidation, and deportation. Ducking and covering is not the strategy they seem to think it is. Soon enough, they will find there's no place left to hide.
I’ve committed myself to learning James Gadson’s brilliant drum pattern on Bill Withers’ Use Me. I’ve got the pattern down now; making it groove is the next big challenge.
“Wildly destructive stupidity.” Nothing like simple clarity.
Oh Susan Collins. Bless her heart.
I’m totally with David Frum on this. We have a lot of farmers in Iowa. If Trump grants them a bailout from his tariffs, which they desperately want, I don’t want to hear them whine about welfare and socialism ever again. They voted for this pig sh*t. They can roll around in it with the rest of us.
Ouch. @benwikler.bsky.social has got game. Congrats and thanks to Wisconsin. We all needed this.
Very proud of my wonderful former doctoral student for Standing Up For Science!
