Our new preprint is out! We show that deviance detection in auditory cortex conveys the theorised comparison of internal prediction to sensory input. Our data confirm this key assumtion that links theoretical models of sensory processing to experimental data. www.biorxiv.org/content/10.6...

Cortical deviance detection represents a canonical difference signal

Context modulates neural processing of sensory stimuli. Neural responses are suppressed to stimuli that are typical in their context and augmented to stimuli that deviate from their context. The latte...

My wonderful co-authors (including @alexjbillig.bsky.social) & I have just published a case report of acquired misophonia & amusia following right temporal resection (including posterior insula). This represents the first case of acquired misophonia. Please find the paper freely accessible below🧠📈

With excellent colleagues at U Iowa including first authors Emily Dappen and @joelberger.bsky.social : a very rare case of acquired misophonia and amusia following right temporal resection: www.sciencedirect.com/science/arti... (and free til mid-Jan here: authors.elsevier.com/c/1mAun1M5IZ...)

I rarely come on here or any social media, but wanted to share our latest preprint of large-scale human single neuron recordings during an auditory working memory task: doi.org/10.1101/2025... I'm very grateful to our patients, my co-authors and the funders. And to anyone who reads it :-) 🧠📈🧵👇(1/5)

Brain-wide single-neuron bases of working memory for sounds in humans

In order to understand the constantly changing acoustic world our brains must maintain elements of auditory scenes in memory. The neural mechanisms for this fundamental process remain unclear. Here, w...

Out now in Nature Comms. To learn a new word, we need to remember it. We track factors driving memory of novel words, showing which words we remember or forget is predictable across people, and isolate a distinct region of fusiform cortex sensitive to this memorability. 🧠📈 #VisionScience 🧠💬 🧵👇

Memorability of novel words correlates with anterior fusiform activity during reading - Nature Communications

To learn new written words, we need to be able to remember their associated letters. Here, the authors show the factors that predict how memorable or forgettable new words are and show a region of hum...

Our new preprint is up now, wherein we directly record from a relatively large population of single neurons in human insula, as well as primary auditory cortex, while intracranial participants passively listen to simple sounds (tones/clicks). doi.org/10.1101/2025... (1/5) 🧠📈🧵👇

Human insula neurons respond to simple sounds during passive listening

The insula is critical for integrating sensory information from the body with that arising from the environment. Although previous studies suggest that posterior insula is sensitive to sounds, auditor...

I'll be presenting the poster below at APAN this afternoon and SfN on Tuesday afternoon, based on the intracranial local field potential and unit data we collect at Iowa. Come and say hi! Thank you to my lovely colleagues and our patients 🧠🟦

A poster on auditory working memory local field potential and single neuron data collected intracranially in humans.

We publish today with @alexwiesman.bsky.social in Progress in Neurobiology another advance in the fight against Parkinson’s disease. Slowing of 🧠 activity is not systematically an adverse effect of pathology: it can also be a sign of compensatory activity that preserves cognitive functions.

Adverse and compensatory neurophysiological slowing in Parkinson’s disease

Patients with Parkinson’s disease (PD) exhibit multifaceted changes in neurophysiological brain activity, hypothesized to represent a global cortical …
