Our brain-computer interface paper was just published in NeuroImage 🧠🫀🤖 We show that motor imagery engages specific brain-heart circuits associated with accuracy and learning through longitudinal sessions: doi.org/10.1016/j.ne...

Well, chatgpt got the two versions of myself at work lol

Thinking about attending ICCN2026 in beautiful Cartagena? We have a dedicated session on brain-body interactions in clinical neurophysiology, together with Jessica Hazelton and @paulasalamone.bsky.social

Pleased to share the acceptance of our #ESCAN2026 Symposium: Dynamic brain-body interactions in perception, selfhood, and cognition across health and disease, featuring Francesca Garbarini, Nicholas Hedger, @jellinap.bsky.social and @paulasalamone.bsky.social, see you in Rome! @escaneu.bsky.social

This Week In HRV Edition - Episode 13 This Week’s Studies: Cardiac-vagal rhythm echoes on the heartbeat's mechanosensory imprint in the brain Candia-Rivera & Chavez — Communications Biology https://www.nature.com/article...

This podcast commented about our recent paper on the vagal effects over the heartbeat strength, published in Communications Biology: heart-rate-variability-podcast.castos.com/episodes/thi...

We kindly asked to replace that reviewer, but our request was denied without further comment. I truly embrace a future with AI-assisted peer review. However, we are not at the stage to fully trust AI capacities on this. A human additional check should remain, especially when concerns are raised.

Since @pnas.org didn't give us reasonable feedback, I want to share with my peers that we recently received comments from an AI-based reviewer (and the only negative one). While many of us use AI to correct readability, this was clearly not the case.

It's because every field call it differently

Cardiac-vagal rhythm echoes on the heartbeat’s mechanosensory imprint in the brain - Communications Biology Vagal-driven heart rhythm fluctuations modulate the heartbeat strength sensed in the head, linking cardiac rhythms to brain mechanosensation. These findings highlight vagal tone’s role in shaping brai...

Out now in Communications Biology 🧠 🫀We show that cardiac oscillations associated with vagal tone influence the strength of the heartbeat as sensed at brain level. We hypothesize that the heart may send information to the brain, encoded by the heartbeat strength doi.org/10.1038/s420...

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 ...

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...

A method for dyadic cardiac rhythmicity analysis: Preliminary evidence on bilateral interactions in fetal–maternal cardiac dynamics Cardiac activity responds dynamically to metabolic demands and neural regulation. However, little is known about this process during pregnancy. Reports show occasional fetal–maternal heart rate coupl...

Nice! We recently showed that mother and fetus hearts listen to each other and react. Since there's no direct nerve link between the two hearts we hypothesized that part of this effect could be explained by mechanosensation doi.org/10.1113/EP09...

📢Fully Funded PhD position in Barcelona!

I'm excited to announce that I’m opening a PhD position at @idibaps.bsky.social, Barcelona!
We'll investigate the role of bodily signals in autobiographical memory, using virtual reality, EEG and TMS, in healthy volunteers and patient populations.

Next week is the world congress of the physiological societies IUPS in Frankfurt 🇩🇪. We have a symposium on the Heart-Brain Axis and also a poster 🫀 🧠. Please get in touch if interested in chatting about science www.eventclass.it/iups2025/sci...

I recently discovered the series Pantheon. The plot around the mind and machines is really cool 🤖

I receive several requests of collaboration. Please don't take it personal if I decline your invitation. I'm just trying to keep coherence on my outputs, but I'm also being extra cautious, since a recent collaboration where I was kicked out without clear reason at the moment of manuscript writing.

Congrats Leah!

More indexed conference proceedings. Every time I see people failing at demonstrating Klimesch brain-body frequency architecture or cardiac-phase stuff is in conferences.

yup that's me

Ah ha! Many consciousness studies might just not be valid, or at least exaggerated. Who would have thought that about this very healthy, pluralist and friendly field of research

Just published our study on brain-heart interactions and COVID-19. We found that brain-heart interactions at the ICU onset indexes mortality risk and acute encephalopathy duration. We also found that maladaptive dynamics are associated with acute cognitive impairment 👾
