Why You Can’t Remember Being a Toddler This form of amnesia is almost universal, but has long been overlooked.

To get a better sense of precisely when #memories are formed and forgotten, Sarah Power @mpib-berlin.bsky.social built a media room where she observed 400 toddlers: "We've been very surprised at their ability to encode and retain these episodic-like memories." time.com/7380496/why-... @time.com

Neuroscience undergrad abducted at 6:30am. No judicial warrant. ICE lied to gain entry into the residence.

State-sanctioned kidnapping. And I’m supposed to somehow teach class this afternoon?

Why can't you remember being a toddler? Or can you?

Nice feature in Time of our lab's work on infantile amnesia at @tcddublin.bsky.social

Also of the labs of @sarahdpower.bsky.social at MPI Berlin, @franklandlab.bsky.social at Sick Kids, and Nick Turk-Browne at Yale.

Do you work or study in the fields of psychology, neuroscience, computer science, artificial intelligence, or philosophy?

What does the term 'representation' mean to you?

We invite you to participate in a brief survey on key conceptual questions across fields.

Imagination in bonobos!

I am thrilled to share a new paper w/ Amalia Bastos, out now in @science.org

We provide the first experimental evidence that a nonhuman animal can follow along a pretend scenario & track imaginary objects. Work w/ Kanzi, the bonobo, at Ape Initiative

1/7 Can infants recognise the world around them? 👶🧠 As part of the FOUNDCOG project, we scanned 134 awake infants using fMRI. Published today in Nature Neuroscience, our research reveals 2-month-old infants already possess complex visual representations in VVC that align with DNNs.

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

Why emotion research is stuck—and how to move it forward Studying how organisms infer indirect threats and understand changing contexts can establish a common framework that bridges species and levels of analysis.

My perspective in @thetransmitter.bsky.social on why emotion research feels stuck and how we might move forward—by focusing on how the brain uses internal brain models to shape emotional processing across species. www.thetransmitter.org/emotion/why-...

Video of the Minneapolis shooting on Reddit shows a group of ICE agents beating a man on the ground. One of the ICE agents then steps back and shoots the victim multiple times.

A nearby witness says “they killed the guy.”

If you have read even a single history of fascism, you are already aware that one thing that its rise has in common in every case is an opposition party that refuses to intervene for fear of looking weak or putting the left into power

Just spoke to The Hill about how the dismantling of the NIH is impacting science in America. We still face a cliff of unfathomable heights, w easily 1000+ labs poised to close in the next year due to funding ending. A generation of young scientists lost because there is nowhere for them to train.
