Looking forward to presenting our work on the origin and flexibility of reward signals at the @arc-mpib.bsky.social next week!

Many thanks to @klaus-tschira-stiftung.de and @gso-forresearchers.bsky.social for this wonderful opportunity to study the mechanisms underlying naturalistic decision processes in the context of foraging behavior!
We’ll also soon have openings for PhD students, stay tuned!

Congrats, that's fantastic news!

We're so proud of this one - great to see it out in @cp-neuron.bsky.social now! See Johannes' threads for what we did & found. Excited to be using TUS and what it will teach us about the neural basis of affective cognition ✨

Amazing! Congrats Debbie - sounds super exciting in terms of topics! All the best for the start

I'm SO pleased to announce that I'll be starting as an Asst Prof at @psychiowa.bsky.social this August.

The lab will focus on neural & computational mechanisms of motivation, affect, & decision-making, with the aspirational goal of translation to neuropsychiatric disorders. 🧠

Looking at the program again 👀 I can't wait for this! Stoked to contribute a talk on ✨the interoceptive basis of reinforcement learning✨

Dissociable dynamic effects of expectation during statistical learning Neural responses during statistical learning reveal dissociable dynamic effects of expectation, supporting the opposing process theory within trials while demonstrating contrasting effects across tria...

🚨New paper alert 🚨

Using EEG and decoding analyses we find dynamic effects of expectation during statistical learning, both within and across trials 🧠

A Movement-Independent Signature of Urgency During Human Perceptual Decision Making - PubMed How does the brain adjust its decision processes to ensure timely decision completion? Computational modelling and electrophysiological investigations have pointed to dynamic 'urgency' processes that serve to progressively reduce the quantity of evidence required to reach choice commitment as time e …

Check out our new paper which isolates a human brain signal that specifically tracks the growing urgency to commit to a choice pubmed.ncbi.nlm.nih.gov/41611534/. This one was a long time coming! Sterling work from @harveymccone.bsky.social and a bunch of past lab members!

The gut-brain vagal axis governs mesolimbic dopamine dynamics and reward events Gut-brain vagal signals gate dopamine ensembles, reshaping reward and motivation beyond a brain-centric view.

"These findings challenge the traditional brain-centric view of reward processing, supporting a more integrated model in which vagus-mediated interoceptive signals intrinsically shape motivation and reinforcement."
Awesome work by @peppeganga.bsky.social & his team 👏

🎉 My PhD work has just been published in @natcomms.nature.com!

How do we learn who caused what - and how much control we had - when outcomes depend on multiple people? We studied how humans do so using a new social learning task, computational modelling and fMRI.

A figure showing that non-invasive transcutaneous vagus nerve stimulation (tVNS) modulates Pavlovian bias in a state-dependent manner. A milkshake vs. water load reduces hunger and these changes are associated with the effects of tVNS on Pavlovian bias.

Last preprint 🎶(of the year).

If vagus nerve stimulation alters motivation by amplifying internal signals, then bodily states should matter. Using milkshake vs. water loads, we show that tVNS-induced changes in Pavlovian bias are dependent on hunger. #neuroskyence 🩺

Non-invasive ultrasonic neuromodulation of the human nucleus accumbens impacts reward sensitivity - Nature Communications This study shows that non-invasive ultrasound to the human nucleus accumbens can modulate deep brain activity and enhance reward-guided learning, offering a potential alternative to invasive neuromodu...

New study out today in Nature Comms: www.nature.com/articles/s41..., in which we set out to test whether ultrasound could influence the reward-related learning computations of the nucleus accumbens, building on decades of work on dopaminergic prediction error and reinforcement learning. And it did.

Come work with us!

Really excited about this 5-year project starting, funded by @wellcometrust.bsky.social, where we will combine ✨computational modelling✨ with causal intervention techniques such as ✨tFUS✨ to study the neurocognitive mechanisms of repetitive negative thoughts 🚀 led by @mikebrowning.bsky.social

These, and other, studies show that you can decode task-related signals from many brain areas.

But wouldn't we need causal manipulations to conclude that the brain "uses" them?

For example, maybe we can decode equally well from two areas. But, only one impacts behaviour when inactivated.

Couldn't agree more with this
