A unifying account of replay as context-driven memory reactivation A context-driven memory model simulates a wide range of characteristics of waking and sleeping hippocampal replay, providing a new account of how and why replay occurs.

Really thrilled that this paper led by @neurozz.bsky.social is now published in its final version in @elife.bsky.social!!

This is a memory-focused (as opposed to RL-focused) account of the detailed characteristics of forward and backward awake and sleep replay!

We've got ISSUES. Literally.

We scraped >100k special issues & over 1 million articles to bring you a PISS-poor paper. We quantify just how many excess papers are published by guest editors abusing special issues to boost their CVs. How bad is it & what can we do?

🚨 Another reminder that corridor care is dangerous.

Patients are collapsing out of sight. Staff are forced to deliver care in unsafe conditions. This is not normal, and it’s not acceptable.

This must change now - that's why we're taking a stance.

Distraught woman says ICE killed her wife in video after deadly Minneapolis shooting
"They killed my wife," the distraught woman says, adding, "They shot her in the head."

"They killed my wife. I don't know what to do," the woman says through sobs in the footage, with a damaged SUV visible in the distance behind her. "We stopped to videotape, and they shot her in the head," the woman cries.
"We have a six-year-old at school," she says, almost unable to breathe, as a chaotic scene in which federal officers prevented at least one doctor who was on the scene from assisting the shot victim unfolds. "We're new here," the distraught woman says in despair.

You and your wife drop your 6-year-old off at school. You just moved here. You see ICE terrorizing your new neighbors. You film them, as is your legal right. Your wife complies with orders. She is then shot in the head. You still have to pick up your child later today.

This could be you.

A Voyage Into the Art of Finding One’s Way at Sea

In my latest for @nytimes.com, scientists and Indigenous sailors in the Marshall Islands are studying seafaring and the human brain. I became completely fascinated by navigation while reporting this story.

What happens in the brain when we manipulate our thoughts?

We asked 30 epilepsy patients to mentally invert short melodies.

Intracerebral #iEEG recordings suggest brain synchrony and sensory inhibition are key for mental manipulation:

Decoding performance (MVPA) better for OPM-MEG than SQUID-MEG 😎. The improved spatial specificity of OPM-MEG due to the reduced brain-sensor distance is key. And more sensors (beyond 40) don't improve decoding.

Psychologists & related fields: what is a big methods question that you believe remains somewhat unanswered & that you'd love to see adressed? There may be an opportunity for a large-scale meta-science project with many teams trying to figure out a question.

Any thoughts welcome! #psychscisky
