validity of phase measures

Published: December 09, 2020

2 different signals, for which the phase is extracted via the hilbert transform. one will get some numerical values for phase in any case, but these values are not always meaningful in a physiological sense, without an oscillation present. pic.twitter.com/UhDStvlwgt

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.
