🚨Happy to share a new preprint from Lerner Lab led by graduate student @nadelneurosci.bsky.social! 🚨 “Adolescent stress recruits a latent amygdala-dopamine circuit to drive punishment-resistant reward-seeking” This has been a wholly impressive effort by Jacob; summary below 👇 #neuroskyence🧪

I joined the Sohal lab with one major hypothesis: psychedelic drugs can be powerful psychiatric treatments, depending on underlying neurobiology. Indeed, psilocybin restored cognitive flexibility in one circuit model of dysfunction, but not another! Then, we had to find out how! 🧠🍄🧪

New preprint led by @christineliu.art! How do psychedelics improve cognitive flexibility? Psilocybin prevents inflexibility caused by aberrant mesocortical error signaling (but not inflexibility due to other mechanisms); this is tied to plasticity of PFC-MD neurons: www.biorxiv.org/content/10.6...

Why do people stop pursuing goals they care about❓ Motivational deficits are among the most disabling symptoms, yet current treatments often have only modest effects. In @lillyt.bsky.social new paper, she asks if we're missing an important piece of the puzzle 🧠 #neuroscience #cogpsyc #psychscisky

I partly blame journal editors for unacceptable conduct such as this. They need to read the reviews before sending them to the authors (isn't this why editors of some journals take weeks to make a decision?) and ask reviewers to modify their reviews if they see inappropriate or unreasonable language

If you don't like a paper, it is obviously totally fine to point out the issues. But please do NOT make egregious and unpleasant comments about the first author's qualifications. A first author who is usually a trainee. Beyond inappropriate and unprofessional.

Congratulations to Professor Wang on winning the Fields Medal (Nobel Prize for Math). Only the 3rd woman in history to win. And she won for a preprint article! We have some ways to go in biology before preprints receive this level of impact and recognition.

Hong Wang, who proved the three-dimensional Kakeya set conjecture, has just won the Fields Medal, making her the third woman in the award’s 90-year history to receive math’s highest honor. Read our profile: www.quantamagazine.org/hong-wang-wi...

Our new study ⬇️inspired by the question: does psilocybin influence meta-learning and cortical processing of unexpected uncertainty? Why is this important? Meta-learning may be critical for therapeutic effects of psychedelics and how the trip creates a window that facilitates clinical intervention

was recently told by a few young scientists to avoid submitting to a (fancy) journal because that journal has bad juju 👹 I laughed but then realized everyone I know who has recently published there has had horrid professional dramas maybe bad juju will finally bring down the publishing enterprise

Breaks my heart that the beautiful and magical south of Iran is being destroyed Nice piece by @arashtehran.bsky.social on the subject highlighting that so many Iranians wished the hardliners “had as much zeal for southern Iran” as they have “for southern Lebanon” www.theatlantic.com/internationa...

Where the War Is Still a War

The southern coast of Iran is still getting battered. Some Iranians want their government’s hawks to see for themselves.
