LED action potential

weekend project: built an LED action potential 💡

I created a few custom feeds for Bluesky based on regular expressions. If a post matches certain patterns, it will get added to the feed (so the occasional stray post appears also). Current feeds include:

neuroscience training courses for summer courses and workshops
job feed based on keywords: cog/neuro jobs
brain rhythms fetching posts about neural oscillations.

Also I played around with building a Bluesky labeler for neuroscience methods. Subscribe to: neuromethods.bsky.social and like the corresponding post to have a shiny methods label appear in your profile. People with specific method labels will be automatically added to method-specific starter packs, e.g. here is the EEG starter pack.

MEG artifacts: railway traction power

Published: April 10, 2026

more MEG artefacts: the tram runs in ~200 meter distance from the MEG lab here. even though the MEG sensors are shielded by a few tons of metal, they still pick up the railway traction power signal (at 16.67 Hz in Germany), a demo of their high sensitivity.

MEG artifacts: metal belt buckle

Published: March 25, 2026

artefacts in MEG: here, the participant forgot to remove a belt with a metal buckle. the buckle moves when breathing, introducing low frequency artefacts. taking off the belt solves resolves this. 🙂

Bluesky vs. Twitter at COSYNE 2026

Published: March 16, 2026

I am interested in network effects in social media & post activity related to recent conferences may be an indicator of this.

Therefore, I counted Bluesky vs. X/Twitter posts mentioning #cosyne2026 hashtags, with more Bluesky posts this time around.

For comparison: during SfN 2025, it was fun to check the hashtag activity for #sfn25 or #sfn2025 here on Bluesky, so I wondered how it would compare to Twitter. Grabbed the number of posts for each day via the API and it seems to be pretty comparable.

time-frequency representation of ECoG data

Published: March 13, 2026

time-frequency representation of human electrocorticography data. 🌊 one axis shows frequency, the other time. the high peaks correspond to a prominent alpha rhythm at 10 Hz which appears and subsides during the experiment.

frequency ratios of brain rhythms

Published: January 23, 2026

if you look into the activity of any brain, usually many different rhythms can be seen. is there any systematic relationship between their frequencies? there are proposals (often by physicists 🙃) that rhythms are organized according to specific ratio, e.g. the golden ratio or simply factor 2.
