Hunger often affects our mood, but is this a conscious or a subconscious process? Using continuous glucose monitoring, we show that differences in mood are driven by hunger ratings, not just glucose. #neuroskyence 🩺

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

🚨 New preprint!

Why do some insights from spikes translate to field potentials while others don't? In this paper we compare visual memory representations in spikes and LFPs to propose a general framework that answers this question.

🧠🟦 🧠💻
Neural representations of visual memory in inferotemporal cortex reveal a generalizable framework for translating between spikes and field potentials
Translating neurophysiological findings requires understanding the relationship between common measures of brain activity in animals (spiking activity) and humans (local field potentials, LFP). Prior ...

New preprint. We show that in addition to reward prediction errors (RPEs), dorsal striatal dopamine signals encode sensory prediction errors (SPEs), the difference between sensory prior & observed stimulus. www.biorxiv.org/content/10.6...
Dorsal striatal dopamine integrates sensory and reward prediction errors to guide perceptual decisions
Perceptual decisions are shaped by expectations about sensory stimuli and rewards, learned through sensory and reward prediction errors. Dopamine is known to convey reward prediction errors that shape...

It happened. One applicant not only mentioned their interest because of a conference abstract we coauthored some day. No, they were captivated by our seminal contribution to a 🥁 Corrigendum.

If you are an applicant using ChatGPT, you must check its suggestions and [insert joke for engagement].

My latest feature for @sciam.bsky.social explores the research connecting problems with interoception to a wide variety of mental illnesses, including anxiety disorders, eating disorders, & PTSD. This work is ultimately circling in on a central message: the body & mind are inextricably intertwined.

Finally, @bjoernhommel.bsky.social's and my paper introducing the SurveyBot3000 is officially out in AMPPS. It's a fine-tuned language model that guesstimates correlations between survey items from text alone. Not perfectly, but useful for search, for example.
