time-frequency representation of human electrocorticography data. ๐
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.
haha, no, I find the sound is just soothing. if it's gone you know that something is wrong. ๐ฌ
need to record the sweet soothing sound of the gas compressor as a sleep aid for home ๐
booked the MEG again to do some final data collection after winter break, always very fun to be there. ๐ (also: my last MEG experiment ever? ๐ฅฒ)
& love our pretty recruitment poster (designed by Claudia Kernberger)
always very cool to see developmental transitions!
reminds me of the large-scale burst type signals of human preterm babies; which become decorrelated after a while. interesting to see this general type of dynamics in young rats. ๐
cosyne people sleeping on the link to dimensionality and latents?
love the loopy nature of this, mirrors my internal state ๐

I could tell who this was about just from the image, very iconic figure ๐
but somatosensation is a great topic, very cool ๐

the initial image is just super typical for resting state (at least 1 + 2), so I was wondering whether I was doing things wrong the whole time ๐ but makes sense @ motor task!
what is the problem?
it looks like a typical posterior alpha + temporal alpha distribution + harmonics?
I learned a lot from Christoph & Paolo when doing TMS-EEG experiments back then. all this methods knowledge now condensed here! ๐
thanks to TMS-EEG, I feel that phase effects for sensorimotor mu-rhythms are now nicely established. (in contrast to visual alpha, which imho still needs work)
brain prize recipients over the years.
I remembered that I made this plot last year for a bias watch project (yes, because of that 2013โ2018 period ๐). the prize for this year will be announced later this afternoon, let's see. ๐ฎ
oscillatory bursts in unexpected places ๐
(even with harmonics!)
methodwise, this paper from @maciekszul.bsky.social may also be interesting ๐ www.sciencedirect.com/science/arti...
thank you! (distance to surfing is a feature dimension with high weighting ๐)
beautiful plots! & structural changes clearly have implications for the strong changes in electrophysiological activity across development.
one aspect that I find tricky: in the HBN dataset, ~70% of participants have a neurodevelopmental disorder, which is not discussed here.
in the background: always the thought whether it makes sense to invest in a commercial space again...
but I guess the early blogging days will not come back (miss them immensely).
yes, the other aspects are:
1) increasing connections between especially ECRs (playful measure/attempt: bsky.app/profile/nsch...) and 2) encouraging people to post interesting stuff (measure: not sure how, except shower some people in likes ๐, but visibility also helps with that)
cool! I played with making regexp-based feeds & it works reasonably well for jobs & training courses, but broader content ones it's tricky, so this is interesting. increasing the visibility of OC here is good. ๐
I feel degree of separation to neurocommunity-accounts could be a useful feature too.
wow! @ data analysis archaeology
I want to see the LFP for this. ๐
the power of procrastination ๐ (I should be writing)
also, just a few more people for a OPM starter pack! (probably these starter packs are most interesting for more specialized methods.)
How dynamics arise from the structure is my biggest interest. In this study, we started with a small step and asked how structure constrains dynamics. Spoiler: would that it were so simpleโฆ (1/6)
now all researchers associated with a label get added to a method starter pack. these are created automatically once a label reaches 10 people or so; updated in intervals; randomized order every time for democracy. ๐ซ
for example, ใฐ๏ธMEG starter pack bsky.app/starter-pack...
there is a bit of a lag when creating the label descriptions. but I checked, now it should work!
strange... you are not in the list of people who liked the methods that I would expect you to. if you did, maybe unlike and re-like?
added DBS!
(mixed feelings about zapping emojis, but for now)
fair fair, I now put at least the kinematics, other things maybe later. ๐
I feel these are more research topics, not neuro methods, no? possibly the related method would be motion tracking/pose estimation?
I think topics are outside of scope for now. ๐
