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.

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...

So happy this paper is now out in @plosbiology.org! We investigated whether fluctuations in MEPs can be explained by phasic influences from internal bodily rhythms, and whether this might happen independently per organ system. #interoception #neuroskyence

How do internal bodily rhythms influence #brain activity & motor function? @tahnee-engelen.bsky.social &co show that #cardiac, #respiratory & #gastric rhythms independently modulate motor excitability, revealing distinct #interoceptive profiles across individuals @plosbiology.org 🧪 plos.io/4nMtpLT

Top: Experimental set up. Single pulses of TMS were applied to the hand area of the right primary motor cortex with an inter-pulse interval randomized between 6 and 10 s. Simultaneously, the neuronavigated coil position (yellow), electrocardiogram (red), respiratory signal (blue), electrogastrogram (green), and electromyography from the left hand (gray) were recorded. The figure shows traces of a 20-s time segment from one participant of the cardiac (raw), respiratory (filtered), gastric (filtered), and EMG (raw) signals. The experimental measure was the Motor Evoked Potential amplitude measured on a hand muscle (first dorsal interosseous), analyzed against the phase of the cardiac, respiratory, and gastric rhythms. Note that the three rhythms have very different periods (~1 s for the heart, ~ 5 s for respiration, and ~20 s for the gastric rhythm). Bottom: Artwork illustrating how rhythms of the internal organs interact with the moment-to-moment fluctuations observed in corticospinal motor excitability. Image depicts an outline of a brain with representations of the three rhythmic organs influencing the motor system: the heart, lungs, and stomach. Image credit: Tahnée Engelen.

This has been such a pleasure to work on and make new friends across the senses! In this review, we compare the evidence for perceptual penetrability across the senses-that is, to what extent cognition shapes experience as opposed to biasing it. High in olfaction, low in gustation is my take home :)

Evaluating cognitive penetrability of perception across the senses Review by Petra Vetter, Stephanie Badde, Elisa Raffaella Ferrè, Janina Seubert & Barbara Shinn-Cunningham Web: go.nature.com/4hOrQeV PDF: rdcu.be/d0K0k #psychology #psychscisky #cogpsy

Flow diagram showing how cognition (red boxes) can influence scene and object perception (green and purple boxes) in audition, vision, pain and haptic perception (arising from a combination of tactile perception and proprioception), olfaction and gustation (with flavour arising from both smell and taste). Cognition also influences tactile perception via changes in body representations (blue box). By contrast, proprioception and vestibular processing (grey) are largely unaffected by cognition.
