#JNeurosci: Tarrasó et al. explored how breathing impacts behavioral and neural representations of memory recall in people. They found exhaling shapes two neural signatures for memory recollection to influence the strength of personal memories. https://doi.org/10.1523/JNEUROSCI.1221-25.2025

How are memories consolidated during sleep?
Excited to share another preprint: hippocampal SWRs route memory content to the cortex via interregional co-reactivation of concept cells, optimized by slow-oscillation–spindle coupling. With the great @tschreiner.bsky.social @humansingleneuron.bsky.social

How does the brain replay memories during sleep?
Excited to share our new preprint, the outcome of an extensive effort led by Johannes Niediek, showing that reactivation of human concept neurons reflects memory content rather than event sequence.

Excited to share our new study on how respiration modulates neural dynamics during successful memory retrieval—led by @estebanbt.bsky.social, alongside the exceptional team of @fabian31415.bsky.social, @maritpetzka.bsky.social, @tobiasstaudigl.bsky.social, and @bstaresina.bsky.social. 👇

A huge extra thank you to all the team who made this possible @fabian31415.bsky.social @maritpetzka.bsky.social @tobiasstaudigl.bsky.social @bstaresina.bsky.social @tschreiner.bsky.social

Hope to see it published soon 🚀

Altogether, our findings unveiled the role of respiration as a pacemaker during memory retrieval, modulating the neural aspects of successful recall and their consequent behavioral response.

Finally, we showed that respiration does not only coordinate α/ß power and memory reactivation separately, but also their interplay. Exclusively in remembered trials, stronger power desynchronizations led to higher memory decodability, again before exhalation troughs.

(6/8)

We further demonstrate that respiration has an impact in concomitant memory reactivation, with memory decodability increasing just before exhalation troughs.

Additionally, the coupling strength between memory reactivation and respiration across trials was associated with memory performance.

INHP = inhalation peak (i.e., inhalation-to-exhalation transition) EXHT = exhalation trough (i.e., exhalation-to-inhalation transition)

Then, we checked that respiration impacts memory retrieval: trials where participants inhaled during cue presentation and subsequently exhaled present better memory performance.

Similarly, we examined its modulation of the EEG, showing α/ß power decreases along the respiratory cycle.

(Top) Time-frequency representation of remembered vs. not remembered trials locked to cue onset. (Bottom) Results from a timepoint-to-timepoint classification, showing memory reactivation after cue onset.

First, we identified the key signatures of successful memory retrieval. We showed a stronger desynchronization of the α/ß band in remembered vs. not remembered trials, and memory decodability happening after cue onset.

(3/8)

Past evidence showed that respiration has an impact in memory retrieval. However, the neural modulation by which respiration leads to an effect in memory recall remains unknown. Here, we assess this issue by analyzing EEG and respiratory recordings from participants performing a memory task.

Very excited to share the first preprint of my PhD thesis!

Together with @tschreiner.bsky.social, we investigated how respiration coordinates signature neural expressions of successful remembering during memory retrieval. 🫁🧠

In our recent @cp-trendsneuro.bsky.social forum article www.cell.com/trends/neuro..., we highlight respiration's potential role in coordinating sleep oscillations and memory consolidation. With the fabulous @tschreiner.bsky.social and @estebanbt.bsky.social

Ready for an exciting day at #ScienceIsWonderful! Together with @estebanbt.bsky.social and Benjamin, we’ll show kids how to become sleep scientists and explore how breathing influences brain activity. Can’t wait to share the wonders of science!
