What happens in the brain when we breathe? 🧠 🔄 🫁

🧠 The functional state of the brain fluctuates across the respiratory cycle

🫁 Brain activity can be volitionally influenced by varying the rate, depth, and pattern of breathing

📈🧠 We're looking for brains! 🧠📈
Postdoc + PhD positions are available to help pioneer fetal MEG with optically pumped magnetometers, measuring prenatal responses to sound and light to understand how we start making sense of the world even before we're born. 🐣

Please get in touch to hear more!

In some way, it's trivial:

The #brain & the rest of the #body (e.g. the #heart) are coupled.

Yet, we spelled it out

📢Our peer-reviewed article about the AffectTracker is finally out! 😲🕹️📈
Traditional methods for rating emotion often miss the dynamic, moment-to-moment nature of feelings. We designed a tool to capture this continuous affective experience in real-time during dynamic emotional stimulation.
Frontiers | AffectTracker: real-time continuous rating of affective experience in immersive virtual reality
Subjective experience is key to understanding affective states, characterized by valence and arousal. Traditional experiments using post-stimulus summary rat...

Miten äänikirjat vaikuttavat tunteisiimme? Tule mukaan aivotutkimukseen! 🧠

Juuri alkaneessa aivokuvantamistutkimuksessa hyödynnetään äänikirjojen kuuntelua ja mielikuvaharjoituksia, jotta voidaan paremmin ymmärtää, kuinka keho ja aivot toimivat yhdessä tunnekokemuksen aikana.

📰 SUMMARY OF OUR NEW PRE-PRINT 📰

Anticipatory Cardiac Deceleration (ACD) is a temporary slowing down of the heart during the anticipation of task-relevant events.
ACD is typically calculated from the amount of increase in R-R intervals on the ECG signal, which is fair enough...

Could the diversity of findings in heartbeat-evoked response (HER) research be due to variability in methods?

In our new preprint my co-first authors, Maria Azanova and @willenjoy.bsky.social, and me systematically reviewed 132 M/EEG HER studies and found:

You’re now breathing manually 🌬️

What underlies this ability to be consciously aware of own breathing?

In our new Journal of Neuroscience paper, we report the largest study to date linking brain microstructure to respiratory interoception.

Microstructural Brain Correlates of Inter-individual Differences in Respiratory Interoception
Interoception, the perception and integration of physiological signals, is a fundamental aspect of self-awareness and homeostasis. While previous work has explored interoceptive processing in the card...
