My very first paper is finally out in @pnas.org, with Catherine Tallon-Baudry and Patrick Haggard! Interoception, exteroception, the self and more, it's got it all.

Also it should go open access at some point

Interoception vs. Exteroception: Cardiac interoception competes with tactile perception, yet also facilitates self-relevance encoding | PNAS
Internal bodily signals, notably the heartbeat, influence our perception of the external world—but the nature of this influence remains unclear. Di...

More on the link brain-heart axis and sensorimotor function, relevant for BCI research 🤖: Different bodily rhythms are coupled with cortical regions at rest. Here we show that motor imagery triggers a decoupling of cardiac dynamics with motor cortex functional connectivity 🧠🫀 doi.org/10.1101/2025...
Imagined movement increases the segregation of brain-heart networks
Understanding the mechanisms of motor imagery, the mental simulation of movement without execution, is key for the development of neurotechnologies. For instance, for detecting covert motor intent in ...

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.

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.

After initially being place on the reserve list, my Academy Research Fellowship has now received a positive result from the Research Council of Finland 🥳 Next year I will be starting my own team where we will work on identifying new interoception-based treatment targets for mental health disorders!

Got Butterflies in your Stomach? I am super excited to share the first major study of my postdoc @the-ecg.bsky.social - Now out in @natmentalhealth.nature.com! We report a multidimensional mental health signature of stomach-brain coupling in the largest sample to date www.nature.com/articles/s44...

"Calls for transforming academia have multiplied over the past decade. These include demands for a change in how the university responds to the climate crisis, how it engages with its colonial past &present &how it is governed [with]calls for truly democratic governance" @ferracimo.bsky.social et al
