It was an honor to be part of this work! Getting the sparse knockout in CA1 to work with dual color 2p imaging — letting us compare Syntaxin3-KO cells to WT cells in the same animal — was particularly challenging and fun 😄

Interesting, thanks! What about tank air — clean enough?

Calling all neuroscientists with optical tables: do you float them with air or nitrogen? Why?

Have used air in the past but am hearing arguments for both and trying to decide which is best!

1st McKinley Lab grad student’s 1st preprint!
@claireang.bsky.social studied how the uterus safely excises massive amounts of tissue during menstruation and pregnancy.

Come for her GORGEOUS images, stay for her incredible discoveries.

How basic neuroscience has paved the path to new drugs A growing list of medications—such as zuranolone for postpartum depression, suzetrigine for pain, and the gepants class of migraine medicines—exist because of insights from basic research.

Awesome article on medical breakthroughs that came from basic neuroscience research in rodents. Major success examples in postpartum depression, non-opioid pain and migraine treatment.

This is exactly why funding basic science is so important!

Very cool and elegant use of a model: “what might we have missed in our data?”

Estrogen modulates reward prediction errors and reinforcement learning - Nature Neuroscience Dopamine encoding of reward prediction errors naturally fluctuates over females’ reproductive cycles with estrogenic signaling due to reduced expression of dopamine reuptake proteins.

Thrilled to share our new paper, out now in @natneuro.nature.com, uncovering how estradiol, the most potent estrogen, modulates reinforcement learning and reward prediction errors across biological levels. www.nature.com/articles/s41...

A “promise of a vote” is no better than a “concept of a plan”

This White House made a choice to pay ICE instead of SNAP and ATC - we could just as easily be flying just fine and feeding people instead of harassing them. Don't cave now

Yep. And it means all that suffering was for nothing because “a promise of a vote” is just a “concept of a plan”

Tell me more about “there’s still time to stop them.” What do we do to stop them?

Sosa Lab - Postdoctoral Researchers We are seeking postdocs to start in 2026!

The Sosa Lab is going to #SfN25 and actively recruiting ✨postdocs✨ with systems neuroscience experience! We study both fundamental memory processes and how memory changes during pregnancy and postpartum.

If you are interested in meeting at SfN, please email me! www.sosaneurolab.com/join/postdoc...

Candid photo of Zara Weinberg. She has short red hair, bangs and glasses. She is laughing.

The Leading Edge Fellows gathered this week to celebrate Zara Weinberg, a beloved member of our community. Our 7th cohort of Leading Edge Fellows (2026) will be named in her honor.

Zara Weinberg passed away earlier this week. She joined my lab earlier this year when her postdoc lab formally closed.
She was a brilliant scientist, supportive mentor, dear friend, avid music fan, rabid believer in public transit, open science champion, and above all just an amazing human.

There are no sufficient words for how profound an impact she had on the Leading Edge community. I'm so sorry for your and all of our loss. We will miss you terribly, Zara

Quantifying funding sources across neuroscience labs We want to hear from you about the sources of funding for your research.

Hi everyone! We are taking a look at the state of funding in the neuroscience field so we are looking for PIs to answer this survey. Please feel free to fill out and share with colleagues.

Ty!

We will be seeking a postdoctoral researcher to join the growing team! If you are a rodent neuroscientist and interested in doing systems neuro work in the mountains 🏔️, please check out the "Join" page.

PIEZO channels link mechanical forces to uterine contractions in parturition Mechanical forces are extensively involved in pregnancy and parturition, but their precise roles and mechanisms remain poorly understood. Here, we identify mechanically activated ion channels PIEZO1 a...

New preprint alert! The uterus expands ~500-fold in pregnancy, yet we know little about how pressures are sensed. Led by @yunxiao-dr.bsky.social, we show PIEZOs are required for contractions and birth in mice, with dual roles of PIEZO1 in muscle and PIEZO2 in neurons

Great news for science and for Stanford!! Laura’s research is amazing! 🤩

Thank you Abhilasha!!! 🤗🤗

Congratulations Chris!! 🥳 Excited to follow the amazing discoveries from your lab!

Will the Senate Save NIH? Rescuing biomedical research is every bit as important as saving Medicaid.

The proposed budget slashes NIH by ~40%, devastating medical research, clinical trials, treatment breakthroughs—life-saving work.

Thousands of lives at risk for tax cuts for the rich? NO THANKS.

Tell your senators to oppose the cuts HERE:

Expanded view of hippocampal function comes into focus After decades of debate, the region’s role is being rewritten. Rather than using sensory input to simply log key points in time and space, the hippocampus may serve to contextualize our experiences…

Great piece from @thetransmitter.bsky.social about the field’s current understanding of the hippocampus! Honored for the nod to our recent paper among these many other excellent studies www.thetransmitter.org/memory/expan...
