New peer-reviewed paper w/ @mheilbron.bsky.social, @predictivebrain.bsky.social & Jakub Szewczyk! Pre-onset brain encoding has been taken as evidence that brains–like LLMs–predict upcoming words. We show that the same signatures arise in systems that cannot predict. (elifesciences.org) (1/8)

Two postdoc opportunities @yale.edu in human neurophysiology. One position in my lab @wutsaiyale.bsky.social focusing on human cognitive neurophysiology. Details at helfrich-lab.com/news/ Plus a possible collab with anesthesiology 👇 #NeuroTwitter #NeuroJobs #neuroskyence #EEG Please share.

🔔PREPRINT: Sleep ripples drive single-neuron reactivation for human memory consolidation 1/9: How does sleep support human memory consolidation? To test this, we recorded hundreds of neurons in the human medial temporal lobe (MTL) across learning, wakefulness, and sleep. doi.org/10.64898/202...

For more than a century, the study of brain lesions has been central to understanding cognitive processes and normal brain function (e.g., Broca’s studies). However, what electrophysiological signatures emerge following a brain lesion?

New in #JNeurosci from Pinggal et al: Medication-withdrawn adults with ADHD exhibit more sleep-like brain activity while awake than neurotypical adults that is linked to poorer performance in a task that requires sustained attention. https://doi.org/10.1523/JNEUROSCI.1694-25.2025

Under Trump, the NIH is giving fewer grants to fewer scientists. The grants awarded are smaller and scientists have less time to spend them. Projects in cancer, diabetes, aging, neurological disorder, and more are going unfunded. “Make America Healthy Again.”

👇 #SleepPeeps Please repost to help me spread the word on this study. This is a very big commitment compared to most "online" studies... but I know there are some good participants out there on the interweb who what to help! 🙂👇

Fresh results now in bioRxiv! 🎉 We know about the function of NREM sleep for overnight memory consolidation. But what about REM sleep? We found that in aging, slow delta waves can intrude phasic REM periods, and this, is associated with worse overnight consolidation 🧠 (1/5) doi.org/10.1101/2025...

Science doesn’t need to be pretty and go according to plan; it just needs to lead to a discovery. If doesn’t have to be done alone or together with someone else; there just needs to be a discovery. It doesn’t need to happen fast or slow; just as long as there’s a discovery, then everybody is happy.

It occurred to me last night that microwaves are kinda like LLMs. Remember when they first came out, people bought microwave cookbooks, and special vented plastic cookware, and they were going to change the way we cooked and ate forever? Now we use them for defrosting mince, and reheating cold tea.
