Using time series graphs to make causal claims be like

One thing I will always give MDPI is that they don't hide what they are. They're fee-for-service publishers and that's it. I don't like, but it's more honest than the "real" publishing houses, who exploit scientists and turn outrageous profits, all while positioning themselves as "the good ones."

Whoa. You can do that?!

Major praise to the @nyulangone.bsky.social podcast team.

I expected just a little internal thing, but they did an AMAZING job digging into the science and creating a great show.

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

@samkrimmelneuro.bsky.social shows the utility of Precision Functional Mapping deep into the brainstem! The red nucleus turns out to be much more potentially interesting for cognitive neuroscience than anyone thought, including connectivity to the Somato-Cognitive Action Network.

The Coming Out of a Transgender Scientist "I know that I am making the right decision because whenever I think about changing my gender role, I am flooded with feelings of relief."

We're disappointed to see Ben Barres's powerful book "The Autobiography of a Transgender Scientist" among the ~400 titles removed from the Naval Academy Library. Needless to say, we're proud to have published his book and will keep it — and his memory — alive.

It's not a bad idea to go to the local Walmart or big box retailer and buy lots of consumables now. From toothpaste to soap, anything you can find storage space for, buy before they have to replenish inventory.

Even if it's made in the USA , they will jack up the price and blame it on tariffs.

Psilocybin’s lasting action requires pyramidal cell types and 5-HT2A receptors - Nature A pyramidal cell type and the 5-HT2A receptor in the medial frontal cortex have essential roles in psilocybin’s long-term drug action.

Our latest study identifies a specific cell type and receptor essential for psilocybin’s long-lasting neural and behavioral effects 🍄🔬🧠🧪

AOC and Bernie in front of the rally crowd in Denver

Zoomed out crowd shot of 34,000 people in downtown Denver with Colorado mountains in the background

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back.

This was the largest political gathering in Denver since Obama in 2008.

Also bigger than the 2024 DNC.

And the largest ever rally in Bernie’s career (and obviously, mine too).

Yes

I'm not sure that our study necessarily implies that one should not average trials - averaging will always have its place. However, our results do show that there is substantial and meaningful variability across trials that is lost when averaging. #neuroscience #neuroskyence
