Hi Bluesky! I guess it's #introduction time!

🎓 I'm Mikkel, I'm a PhD student at University of Sussex dabbling at the intersections between computational ethology, #neuroethology and behavioural ecology.

✨ Super stoked to announce that I will soon be joining the #SLEEB-Lab with @roesslerdaniela.bsky.social at @unibonn.bsky.social! Really excited for what’s to come!🕷️💤

Two awesome news for our #SLEEB-Lab @unibonn.bsky.social 1) we finally had a lab photoshoot and 2) I can now officially announce @roald-arboel.com is joining our team as a Postdoc starting in November!!! Sweet tracking stuff ahead. Welcome to the #spider #behavior fam, Mikkel!

Breaking News: Jane Goodall, one of the world’s most revered conservationists, died at 91. Her discoveries in the 1960s about how chimpanzees behaved in the wild broke new ground and represented what was called “one of the Western world’s great scientific achievements.” nyti.ms/42kpGxt

I’m super excited to finally put my recent work with @behrenstimb.bsky.social on bioRxiv, where we develop a new mechanistic theory of how PFC structures adaptive behaviour using attractor dynamics in space and time!

Might be something I need to have a closer look at for a current project which currently uses {reactable} and {crosstalk}. Have you seen any examples of styling a table as a car view by any chance?👀

Mikkel Roald-Arbøl @roald-arboel.com · Aug 30

This is probably the one I have the highest hopes for to provide good privacy - really hope @proton.me up the open source game for Lumo!

For now just on the data structure in the 2/3 and 3/3 subskeets. 😊 If you have a fellowship in mind, then feedback on the form would also be helpful: opnform.com/forms/eu-fel...

Love that you’ve included that detail!

Turned out that Nature solved the problem with hardware rather than software!

Funny you should mention it: It was my PhD supervisor’s PhD supervisor Malcolm Burrows who discovered these “cogs” - it solved a conundrum in both biomechanics and neuroscience: Neural coordination, even with its millisecond precision, would be way too inaccurate and the jumps wouldn’t work!

I guess I’m just speculating about whether the tech is there so it’d be possible to avoid taking a sample. The difference is likely tiny, but, especially in the times, I’d rather not leave the door open for “but what if the sample was different”-arguments that I’d attempted to twist the facts.

This looks great, thanks for sharing! Seems to be an abandoned project - maybe worthy of a fork to add a density plot 👀 (argh, must resist another project!😅)

Mikkel Roald-Arbøl @roald-arboel.com · Aug 27

Ping @gmcd.bsky.social just because I know you dabble so much with duckdb. 🤞

Mikkel Roald-Arbøl @roald-arboel.com · Aug 27

#rstats folks, is anyone aware of whether it is possible to plot data loaded with @duckdb.org - say I want to generate a density plot on a data set that's too large for in-memory?

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇

Interoceptive Ability is Unrelated to Mental Health Symptoms: Evidence From a Large Scale Multi-Domain Psychophysical Investigation

Interoception-the sensing and perception of the internal viscera-is widely cast as a transdiagnostic mechanism linking brain-body interaction to mental illness. Prevailing models propose that altered ...

Could someone try to submit a fellowship to the #EU #Fellowship Database - and give some feedback on the form: Is everything clear? Have I missed anything? Feel free to just try it out with a fictive fellowship (please label the title as "FICTIVE").

Inspired by @deniswirtz.bsky.social and team, I'm collating a database of #PhD and #postdoc fellowships in the #EU. I'm standardising the information an entry needs, making it easier to (1) search and (2) contribute - and I would appreciate input, especially from other #ECR! Please share!
