burst parameters and resulting spectra

Published: August 20, 2020

lots of EEG studies are looking at changes in oscillatory alpha-power. but different types of time domain changes can manifest as changes in alpha-power. for instance, de-/increases in:
- duration or
- number or
- amplitude of oscillatory bursts. pic.twitter.com/voHmOvac9e

Bluesky for neuroscientists

Published: April 19, 2026

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.
