I mean, of course there are heartbeat evoked potentials, but I think they are some magnitudes smaller in amplitude. π

from my understanding: pretty much only artifact. in non-invasive EEG it's very localized, only on 1 channel = unlikely to be of neural origin (more spatial spread otherwise).
here, the signal also only appears on 1 electrode. electrodes are far apart, difficult say something about vessel-closeness.
intracranial EEG artifact: if an electrode is located over a blood vessel, you can occasionally see some nice rhythms. sadly, these are not neural rhythms, but reflect the pulsation of the blood vessel, which moves the electrode around slightly. can also be seen in non-invasive EEG occasionally.
definitely agree with you on the ASAP! we need community standards fast, given the usage by PhD students who are under pressure to obtains results quickly, but have limited domain knowledge to even evaluate the AI outputs => occasionally feels like watching a car crash in slow motion... πΆβπ«οΈ
small joys π
we have a themed bathroom on the ground floor of the institute π
(designed by our fantastic graphic designer Claudia Kernberger)
Really happy for my awesome colleague Jiajie Zou! He is now leaving us for a postdoc at the MPI for Biological Cybernetics. TΓΌbingen folks, please give him a warm welcome, aka invites for talks and such. π
very cool topic!
we record at 12 kHz to look at some fast responses. it just that the files become large and annoying to handle & for things that people usually are interested in, a much lower rate is sufficient, as you said. π
Mon-Thu: reformat figure legends for the 17th time and other equally exciting tasks, mild questioning of life choices.
Friday!: look at the brain in real time! π€©π
the median number of authors on a research paper who are familiar with the underlying code: 1
it generally feels like that number will decrease even further, honestly a quite scary development. πβ¬οΈ
very surprised to learn this, don't the editors know you exist given that you are a former editor?
(I get like at least 5 requests per month and assumed it would be similar for other people)
"delta" activity across species π
wrestling with the bureaucracy is an art in itself, but sometimes there are creative ways, or they can be created.
continue the advocacy, if it comes from male established professors (the more grey hairs the better), the chances of success are increased. π
time extensions (contracts & grants): great, but if they are not applied automatically, it leaves you at the mercy of bureaucrats & PIs.
small grants for travel & etc: great, but why do organizers & agencies need like 10 documents & 2 rec letters for such limited $ amounts?
core requirements as always: time & money.
e.g.: UCSD childcare $2,6k per month = over 50% of postdoc salary (& long waitlist also). I talked to a research director who felt it was out of scope for him to be concerned with that. but maybe these 'fringe topics' should be more front & center.
I agree, the responsibility for structural problems is shifted to the individual. I am sure the article is well-intentioned, but the advice here is very supergeneric (plan & communicate), which probably reflects the fact that there is not much room for what you can do as an individual.
beautiful race! & such a well-deserved win π
wow beautiful blog post!
π
but I am not complaining, other than that the data in Frankfurt is really nice! (compared to the artefacts in NYU data, which are 1 hot mess)
but please still do setup the camera!!
sometimes I feel 50% of my posts are just advertising for SSD/GED type methods, it's really super powerful. π
yes, I myself was just curious if it could be something more in my data. π
before posting, I asked my fav local MEG expert whether it could be something else given the almost magical nature of artefacts, but they were not aware of other 16.67 Hz sources. would be curious to know!
π fun + great procrastination project.
but I think you can easily regress this out with SSD (which I used here to extract the component) since it's so narrowband.
(would be fun to xcorr this with videos of trams arriving and leaving, but sadly I don't have time for this π)
component isolated from resting state MEG data
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.
I thought these where only to show reviewer #2 that I am a true scholar. π
crazy that people actually read these! π
