Surprisingly, the block prior was represented by few neurons in very few regions. To investigate this further, we devoted a whole companion paper to it, where additional analyses discovered widespread representations of the prior. (7/8)

We are excited to present a Brain-Wide Map of neural activity during a complex decision-making behavior, a product of the monumental effort of 22 labs: 547 Neuropixels recordings in 267 brain regions from 115 mice collected in 11 labs 🐭 (1/8)

Is food addiction real? Apparently if it is “ultra-processed”

As Van Tulleken explains, “Addictive products are not addictive for everyone. Almost 90% of people can try alcohol and not develop a problematic relationship; many can try cigarettes, or even cocaine.” Equally, not everyone who eats UPFs will become addicted – but, based on current studies, one in seven will. “Many UPFs for many people are addictive,” Van Tulleken summarises. “And when people experience food addiction, it is almost always to UPF products.”

Excited to share our _open access_ paper in Nature Neuroscience investigating the role of the rat frontal and parietal cortices in economic decisions under risk.

We found that silencing the frontal orienting field (FOF) in rat secondary motor cortex increased risk-aversion and we could decode the value of the lottery on each trial from the population activity of the FOF.


p.s. We are looking to hire a postdoc to work in mice models of economic (esp. strategic) decisions. Message me if you will be at SFN and would be interested in working at the amazing @SWC_Neuro

I was wondering what right now must feel like for the Israelis that have been fighting the Netanyahu government and/or pushing for an end to hostilities with the Palestinians. The visceral pain of the brutal terrorism Israel experienced has to conflict with the awareness of the inevitably brutal response that is happening/coming. That tension must be unbearable.

blavaan 0.5-1 is now on CRAN, including initial functionality for two-level structural equation models. Estimation happens via #mcmc_stan

If you don't know these models, they are multivariate Gaussian models with three levels (e.g., multiple response variables within people within schools).

“Our study revealed a previously unknown cooperative thalamocortical circuit mechanism in which the VIP neurons work as a switching board. When VIP neurons are off, pulvinar suppresses the neocortex, but when VIP neurons are on, pulvinar can boost the neocortex. Sensory prediction error signals thus emerge through a collaborative action of neocortex and thalamus.”

Shohei Furutachi and colleagues in the Hofer and Mrsic-Flogel labs have shown how sensory prediction error signals arise in V1, in a new preprint.

🔬🧠🌐 The Neuro-Cooper Open Science Prizes

I am thrilled to announce that the 2023 Neuro-Cooper Open Science Prizes are officially open for applications! For those unfamiliar with the prize, it stands as a beacon in the scientific community, recognizing and rewarding both junior and senior researchers who are pushing the boundaries of open neuroscience.

Check out the full details of the application process here

Three years ago, we launched this prize with a simple yet ambitious goal - to elevate those who embody the spirit of open science, fostering collaboration, data sharing, and transparency within neuroscience. Today, the Neuro-Cooper Open Science Prizes have become a respected staple in our community, and I am humbled by the impact it has made.

On a personal note, after serving as the chair of the selection committee for the last three years, I have decided to step down from my role. The journey has been enlightening, full of inspiring people and innovative ideas. I'm so happy that Thomas Duncan has accepted to take over the committee, perpetuating our shared commitment to open science.

As we open the floor for the 2023 applications, I want to extend my gratitude to all the researchers, collaborators, and institutions who have made the Neuro-Cooper Open Science Prizes what it is today. Your relentless pursuit of open and collaborative science is the driving force behind this initiative.

To the future applicants - I can't wait to see how you're transforming the world of neuroscience. Keep breaking those boundaries!

I slightly wish the media would switch its messaging from "We're all gonna die!!!" to "Here's what we need to do to stop the dying" (starting with - defund the fossil fuel companies and vote environment...)

I finally carved out some time to sit down and finished what I promised
@steffilazerte almost 15 months ago.

I wrote about how I use the r-universe (by @rOpenSci) to not only deploy The #CarpentriesWorkbench packages, but also stable versions and bugfixes _for its depenendencies_.


Congratulations to @lili on a superb PhD defense today!

I went to sign some books at Woodstock's The Golden Notebook bookshop today and they gave me this book as a thank you. Two hours later her death was announced.

Nurture versus nature:

"Betty Hart and Todd Risley wanted to know why, despite best efforts in preschool programs to equalize opportunity, children from low-income homes remain well behind their more economically advantaged peers years later in school. Each month, they recorded one full hour of every word spoken at home between parent and child in 42 families, categorized as professional, working class, or welfare families. Two and a half years of coding and analyzing every utterance in 1,318 transcripts followed. By age 3, the recorded spoken vocabularies of the children from the professional families were larger than those of the parents in the welfare families. Between professional and welfare parents, there was a difference of almost 300 words spoken per hour. Extrapolating this verbal interaction to four years, a child in a professional family would accumulate experience with almost 45 million words, while an average child in a welfare family would hear just 13 million—coining the phrase the 30 million word gap."

I don't think everyone realizes how much #neuroscience #opendata is really downloaded and reused...

e.g. our dataset of responses to visual stimuli has 18,000 downloads; wholebrain #zebrafish neural activity from the Ahrens lab has 7,000 downloads; Nick Steinmetz's eight-probe Neuropixels data has 6,500 downloads. and there are many commonly used neuro datasets on websites that don't count downloads that must have thousands too!

post your data and they will come :) #openscience

We are delighted to announce that Tim Behrens (@behrenstimb) has joined SWC as a Group Leader.

The Behrens Lab will strive to understand the neural mechanisms that support flexible goal-directed behaviour. In doing so, the team hope to build new bridges between human and animal neuroscience, between biological and artificial intelligence, and new methods for integrating across scales of neural activity.
