The International Conference on Retinal Proteins (ICRP2026) registration and abstract submission are now opened!!! www.congressi.unisi.it/retinalprote...

The buzziest neuroscience papers of 2023, 2024 The field took note of work on brain-computer interfaces for speech, the mechanism of psychedelics, defining hippocampal representations, and more.

The field is buzzing about work on brain-computer interfaces for speech, the mechanism of psychedelics, a broader definition of hippocampal representations and more.

Our microbial-opsin work (and most of the field ) is basic science, but it was intriguing to review clinical progress–direct & indirect–with a wonderful team of co-authors

Really cool stuff! Engineered excitatory opsins responding to 15nW light

A Letter by Israeli Social Psychologists Dear friends of the Social Psychology community, After October 7, a group of Israeli social psychologists, including many of us, wrote a letter expressing our deep shock at the massacre, abuse, rape,...

Breaking a hiatus to post this.

A group of Israeli Social Psychologists, myself included, wrote a letter to speak out clearly against the Israeli government’s decisions and the resulting devastation in Gaza.

Cries into ties Oxytocin neurons in mouse pups regulate vocalization to maintain maternal bonds

Very cool study by @oyiz.bsky.social using optogenetics to shed light on how oxytocin signaling regulates vocalization to maintain maternal bonds (with nice write-up by @bellonec.bsky.social, “Cries into ties” indeed) 🧪

Congrats Noa, Yuval and the team! Beautiful work!

And to Shari Ross for the beautiful drawings

Many thanks to my amazing team at @weizmanninstitute.bsky.social, our colleagues at the Dept. of Brain Sciences and at the Dept. of Molecular Neuroscience and the generous support of @erc.europa.eu and the NIH BRAIN Initiative

Oxytocin shapes both mouse mom and pup behavior Distressed pups emit distinct cries for help, which depend on oxytocin neurons in their hypothalamus.

Oxytocin signaling regulates maternally directed behavior during early life Oxytocin is essential in shaping social behavior across the lifespan. Although the role of oxytocin signaling in parental care has been widely investigated, little is known about its function in socia...

This study was led by my fantastic PhD student Daniel Zelmanoff and a wonderful team from the lab. Check out the full paper here: www.science.org/doi/10.1126/...

Using this approach, we were able to show that silencing oxytocin neurons specifically alters the vocal behaviors of pups when they are separated from their dam and littermates, and also alters their vocal behavior upon reunion.

Since optogenetic manipulations are very difficult to perform at such a young age, we devised a new approach that uses our mosquito opsin eOPN3, which is red-shifted and highly light-sensitive, for transcranial silencing of hypothalamic oxytocin cells in freely-behaving pups.

We found that oxytocin neurons are activated during a 3-hour separation from the home cage, and are also transiently recruited during the emission of ultrasonic vocalization bouts.

This study was ignited by the discovery that oxytocin receptors reach peak expression in the brain during early life - both in humans and rodents! In mice, P14-21 and in humans from birth to 3 years. We wondered how oxytocin contributes to behavior at this critical period in an animal's lifetime.

Excited to share our latest paper - now out in @science.org - we showed how oxytocin modulates maternally-directed behavior in young mice (P15).

In the past year and a half, we have been intensively protesting and fighting the Israeli government in an attempt to stop the war, secure the release of all hostages, and prevent the ongoing humanitarian crisis. Until now, our protests have primarily been focused internally.

What time is it? ⏰
Time to talk about the brain! 🧠

Opening the Neurotechnologies plenary session is @oyiz.bsky.social of Weizmann Inst. of Science. He is discussing new tools that allow highly light-sensitive silencing AND facilitate spectral multiplexing for modulation + imaging.

Also, a thread 🧵 below.

One difference is that the DIO approach leads to the permanent removal of DNA, making it irreversible. For SIO an equilibrium between forward and reverse recombinantion is created. However the reverse probability is low, creating a bias to the activated state. In practice expression levels are good.
