Does aperiodic activity index neural excitability?
Single-unit and LFP recordings during optogenetic interneuron suppression show that aperiodic activity scales with firing, but it depends on context and oscillatory power. New preprint with @juliaveit.bsky.social.

Can we really measure replay in humans using MEG with current methods? In our most recent paper we simulated replay under realistic conditions via a novel hybrid approach with astonishing results.
we're delighted that it has now been published @elife.bsky.social!

Out now in @natcomms.nature.com, our latest from @bodybrainbehaviour.bsky.social: Visual perception, oscillatory excitability markers, and network connectivity are modulated by the breathing rhythm - depending on how much you know about the stimulus.

I am very happy to share our latest paper, just published in @currentbiology.bsky.social! In collaboration with Olga Garaschuk's lab, we used in vivo 2P calcium imaging to investigate the role of sleep spindles in the hippocampus. 🧠💤

Conjunctive population coding integrates sensory evidence to guide adaptive human behavior. New work led by @jonasterlau.bsky.social in @pnas.org. We used human intracranial EEG to understand how coordinated population activity supports context-dependent behavior. www.pnas.org/doi/10.1073/.... (1/4)
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

Almost always we average responses thus equating response variability with noise.
Well, we shouldn't because variability is also signal, not noise to be entirely discarded.

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
Finally I am looking for a motivated student assistant (HiWi, 80 hours/month) at Uni Freiburg (Neuropsychology) 🧠
Project on sleep, EEG, heart–brain dynamics & memory.
MATLAB/Python a plus.

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.
We are delighted to invite you to the upcoming “Psychology and the Brain” conference, which will take place in Heidelberg from June 3 to 6, 2026. Conference registration and submission of contributions are now open. Visit us at pug2026.org

BOLD signal changes can oppose oxygen metabolism across the human cortex, Nature Neuroscience
fMRI signals “up,” but neural metabolism might be going “down.”
In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes.

Aperiodic activity reflects pathological waveforms in epilepsy (and not necessarily hyper-excitability or altered E/I-balance). The 1/f slope goes up *or* down as function of waveforms during seizures. New work by Laura Heidiri and Frank van Schalkwijk from the lab: www.jneurosci.org/content/45/5...

If comp neuro, ML, and AI4Neuro is your thing, or you just nerd out over brain recordings, apply!
I'm at neurips. DM me here / on the conference app or email if you want to meet 🏖️🌮
It’s not too late to apply for the PhD position in my lab! Please send your documents (cover letter, CV, transcripts, names of references) through the official application platform by Nov 25!
At #SFN2025? Into sleep, brain rhythms, or single-unit–based memory reactivation? Then you absolutely should check out @fabian31415.bsky.social's poster. I might be biased, but this is some truly awesome work.
