Preprint of collaboration with @lauradata.bsky.social. We found that infraslow slow sighing at a frequency recently linked to glymphatic clearance (0.02-0.03 Hz) produced significantly higher CSF-BOLD coupling than other breathing regimes. www.biorxiv.org/content/10.6...
Effects of different slow paced breathing regimes on cerebrospinal fluid (CSF) oscillations
Cerebrospinal fluid (CSF) transport is crucial for clearing waste from the brain and is largely driven by blood vessel oscillatory dynamics. During non-REM sleep, large oscillations occur in the infra...

#Respiration influences neuronal activity, and recent work suggests that respiratory phase is coupled to the cortical readiness potential. This study challenges this link and reports that the previously identified association arises from movement onset confounds. 🧪 #AcademicSky plos.io/4ybvJBU
So proud of @teresaberther.bsky.social 🫶🏻 What a beautiful milestone for your first first-author paper - and such a special piece of work to have out in @plos.org
Nothing quite like finding a perfect home for work close to your heart. Out now in @plos.org CompBiol is our #open-source toolbox for circular permutation testing in #brain-body #neuroskyence. 🫂 @teresaberther.bsky.social & @eliobalestrieri.eurosky.social 🔗 journals.plos.org/ploscompbiol... 🧵🔽
📣 My lab at NYU currently has two open post-doc positions. We are interested in understanding perception, thinking, and hallucinations. We employ a range of cutting-edge techniques in human neuroscience (e.g., 7T fMRI, MEG, iEEG/DES) and computational approaches (e.g., DNN modeling).

Sensing your body (‘Interoception’) is everywhere in theories of mental health. But when we tested how well hundreds of people sensed their heart and lungs, the link to symptoms was almost nowhere to be found. 💣 🚨New @natmentalhealth.nature.com paper 🚨🎉 asks why 🧵 www.nature.com/articles/s44...
Can we study MTL ripples non-invasively? New preprint! We show that source-resolved MEG tracks ripple-like activity during sleep that: • localizes to the MTL • follows the canonical SO–spindle hierarchy • matches an iEEG benchmark • indexes memory reactivation www.biorxiv.org/content/10.6...
Non-invasive tracking of ripple-like activity during human sleep using MEG
Hippocampal ripples are considered a key mechanism of sleep-dependent memory consolidation. In humans, however, their direct investigation has relied on invasive recordings from patients with epilepsy...

Neural mechanisms of time-forward predictions for naturalistic auditory tone sequences - Nature Communications
A longstanding question is how the brain predicts complex, naturalistic sensory events and updates those predictions when expectations are violated. Using intracranial recordings, the authors show tha...

Latest preprint from @bodybrainbehaviour.bsky.social by @teresaberther.bsky.social and @martinasaltafossi.bsky.social on cardio-respiratory modulation of arousal and excitability states in the human brain - overlap, distinctions, and implications for brain-body #neuroskyence. osf.io/preprints/ps...
Our new article is out! 🧠🫀 We investigated heartbeat-locked brain activity using #MEG and found that beta-band suppression was enhanced during interoceptive attention and in individuals with higher interoceptive accuracy. #neuroskyence #interoception @uniofjyvaskyla.bsky.social

This study shows that beta-band suppression time-locked to the heartbeat is a reliable neural marker of interoceptive processing, with a distinct fronto-cingulo-somatosensory signature that different...

🎉 Excited to share our publication in PNAS! 🎉 What happens when our stream of consciousness turns towards the body? Our fMRI study of 536 individuals finds that 'body-wandering' is associated with patterns of brain connectivity, physiology, affect, and mental health: www.pnas.org/doi/full/10....

Is there a single "interoceptive sense"? Our new study in @commspsychol.nature.com says: probably not. In 241 participants, cardiac and respiratory interoception were completely uncorrelated — only subjective confidence was shared across domains. www.nature.com/articles/s44... #psychscisky 🧪
Incredibly excited to finally share this project! Most heartfelt thanks to everyone involved for their support 🫶🏻 Looking forward to much more gut-brain research to come!

Ripple oscillations are central for memory and sleep. But ripple detection in humans remains challenging. Here we introduce a simulation approach in @natcomms.nature.com as common ripple detectors mainly pick up 1/f noise and not genuine oscillations 👇 www.nature.com/articles/s41... #neuroskyence
