2/n. The retina is as complex as any other part of the brain, but uniquely accessible to detailed structural and functional analysis. The basic plan of the vertebrate retina is exceptionally conserved across vertebrate species that diverged ~400-500 million years ago.

Neuron's latest issue features two interesting critiques that could be seen as examples of the Freudian 'killing your father' concept. What's amusing is that both critiques are by Dutch researchers (Roelfsema-Vinck) addressing ideas proposed by German scientists (Singer-Fries).

I asked #ChatGPT to list scientific paper estimating prevalence rate of depression in young adults. The estimate rates made sense, and paper titles and authors all seemed (vaguely) familiar.
But none of the papers actually exist.

I spent the weekend playing with ChatGPT, MidJourney, and other AI tools… and by combining all of them, published a children’s book co-written and illustrated by AI!

Here’s how! 🧵

Neuroscientists and psychiatrists really should read this.

**NEW PREPRINT ALERT** co-authored w/ @seb_trem (yes, 2nd in a week!!)

We show that inferring a brain area’s function from neural recordings alone can be misleading, with severe consequences to the field of neuroscience.

Glad to share our new paper out in @PNASNews "Whole-brain neuronal MCT2 lactate transporter expression links metabolism to human brain structure and function"! We use a whole-brain strategy to explore the metabolism of the most energy-expensive organ!

A thread!🧵 (1/N)

Very happy to share our latest preprint, where we explore how individual differences in the diversity of everyday experiences relate to event segmentation: https://t.co/yzd1hxjQe3

You may remember the recent NatureMedicine paper where authors claim to show—as the first author says below—that psilocybin "liberates the entrenched depressed brain". This led to considerable news coverage.

3 pretty remarkable things have happened since this was published 🧵

This debate is getting deep into the discrepancies between how Science should work and how it actually gets done. The issues being raised are simultaneously serious and commonplace. In much of science, the relationship between the storytelling and the data is loose. 1/5

Very proud of this one: “Neural oscillations across olfactory regions encode odorant information in the teleost olfactory system” (🧠🐟). A transatlantic collaboration led by @extoxicon, with @PatricioOrio, Viktor Sadilek, and Oliver Schmachtenberg. Thread below 👇🏽!

Check out paper published today!!!
We review human and non-human primate brain mechanisms for rhythmic and multimodal integration of faces and voices. We also address the relevance of these mechanisms for speech evolution and development

The dominant practice of modeling in neuroimaging is to split the analytical pipeline into two or more steps: subject and then population. The population-level model only involves the number of subjects, so the number of trials or scanning length has no impact on stat efficiency?

I have THOUGHTS and OPINIONS on the current psychedelics 'gold rush', and I pitched an article on it to @ConversationUK, but they don't seem interested, so I'm just going to do a 🧵 here instead, you lucky people. ⬇️ 1.

Important paper re brain-behavior correlations, effect sizes, & sample sizes. Don't view the results as a dig on previous research, but as promise for the future. Information is power; if we are aware of the issues, we can work toward exciting discoveries

Have you ever noticed how nature seems to love symmetry?🔺🟥🔴

Evolution has literally trillions of shapes to pick from, and yet, biological structures often show symmetry and simplicity.

This is the story of the discovery that completely changed how I see biology. 🧵

🚨New preprint on how time pressure⏰ influences human exploration with @cpilab @MaartenSpeek @tpleskac. Through behavioral, RL, RT, and drift modeling, we find that time pressure induces a resource-rational shift towards lower-cost strategies
