New preprint out! In this opinion paper, we review our recent work showing that frontal beta frequency shifts signal categorical decisions. We propose that the observed frequency modulations emerge from the recruitment of distinct neural ensembles when different (categorical) decisions are made.
Beta frequency shifts in decision making: Spectral fingerprints or communication channels?
Recent evidence suggests that beta-band activity plays a key role in decision-making. Here we review our recent work in humans and non-human primates showing that beta-band frequency shifts in frontal...

thank you for listening to my EEG TED talk! (the vibes from these chairs 😅).
we ran a MNE-python tutorial for >100 people for a week. the program going from preprocessing to source estimation to group analysis was ambitious, but I hope seeing all the steps involved was helpful for participants. 🙂

this week at #PracticalMEEG2025 in Aix!
having run an MEG pipeline by trial and error, I was doubting myself between all parameters. lectures on the analysis steps + hands-on application together were very helpful!
& seeing women on stage sharing what they're excited about just hits different ⭐️

I always learned a great deal from simulating data (aka mostly how things don't really work the way they are advertised 🙃).
so I can definitely recommend playing with this toolbox for simulating EEG/MEG sources with desired properties (location, coupling) for connectivity. ⬇️

We (I and @willenjoy.bsky.social) created a toolbox for simulations of EEG/MEG because we needed to simulate data. Our initial aim was to simulate connectivity. For this short clip, I simulated two sources with phase connectivity using our toolbox.

made a mini-game for events: find pairs of matching brains, the Allen mouse brain & a macaque brain are smuggled in to make it easier. meanwhile, we can talk about brain structure, cortical folding, twins, individual differences, & etc. 🙂💗🧠

this looks great! (+ cool plots)
given that alpha rhythm is often decreased in frequency (e.g. 8 Hz instead of 10 Hz) for epileptic patients and this is #iEEG data, I find it tricky to call this theta-activity; but it's also different from classical mu-dynamics (Fig. S4). 🤔

ok, imagine you have an oscillation that is not symmetric around 0 (small direct current shift) with some amplitude modulation, for instance with 1/f-dynamics.
➡️ then these 1/f-dynamics will show up in low frequency part of spectrum (red); in addition to around oscillation peak (yellow).

I love baby EEG, so had to check this! here, a dichotomy is drawn between theta & alpha rhythms, but this is tricky. the posterior dominant rhythm emerges in the infant at 3-4 Hz & increases until ~10 Hz in adults. I think there is much evidence that this 'theta' rhythm is the equiv of adult alpha.
In an EEG study spearheaded by Marlena Baldauf, we show that 8-month-old babies’ visual systems resonate at 4Hz (theta rhythm) — unlike adults, who resonate around 10Hz (alpha).

a seemingly general electrophysiological phenomenon: once you have to process stimuli, low-frequency rhythms disappear, spectrum becomes flatter & sometimes an increase in broadband gamma activity.
we also found this for visual memory encoding in #iEEG data: doi.org/10.1523/JNEUROSCI.2404-24.2025

this figure from 1944 is cited as the first topoplot, from Koiti Motokawa. in an era where only handful of EEG channels across space were used, he measured the mean alpha amplitude for 90 points across the scalp. ❗

something curious I noticed when working with this dataset, related to the ease of access for different data components. I am not exactly sure what to do with this observation, but here you have it:

oscillation frequency changes across development (one of the most robust findings in the oscillation world). in this work, we also look at waveform shape changes.
