Time for my #neuroscience #introduction here. I am studying the nervous systems of jellyfish using computational modelling, trying to understand their dynamics and their evolution. I use biophysical neuron models and feed the resulting dynamics of their network into fluid dynamics simulations to study how their neuronal dynamics control the swimming and turning of these strange creatures.

@Mill_lab @florianjug While I left the other site behind, I still keep a foot there to drag out stragglers.
On the energy, it's deliberate. This is a time of great opportunity to shape the public discourse channels of the scientific community for years to come. So I got to work to assist as best I know.
I've been in online communities since 1995, when my parents bought an intel 386 "clone" (as we called them back then) with (the horror) MS Windows 95 and dial-up internet. Living in online communities comes natural. Been a moderator of IRC chats, poetry forums, software forums, and more, for decades.
One aspect I see as key is a variation of the founder effect: nobody moves unless there's something to move into, and there won't be something to move into unless most move. To push over this bistable system into its other state, energy must be applied. Here, "something" is both interesting commentary, links, news, photos, and more, as well as people with similar interests.
Putting in energy (time and effort, really) at the beginning can make a dramatic difference to the outcome. My approach was then, indeed, deliberate: post here what I used to post on the other site, reach out to those who have moved and engage with them, lure those on the other side with links to here and never the other way, promote here relevant news (job posts, conferences, papers) and showcase examples of community-triggered switching (publishers and journals), stimulate commentary, seed insight.
Eventually I'll wind down, but at the moment, this fire needs kindling. So far, so good.

We have an exceptional opportunity at our center for a new group leader at VIB in Leuven. We are looking for a new colleague who wants to use computational methods to investigate molecular and/or cellular aspects of neurobiology. This position not only comes with substantial and renewable core funding and start-up package, but it is also linked to a tenure track position at KU Leuven.
More information on our center can be found on our website https://cbd.sites.vib.be/en.

Neuro-evo conference at HHMI Janelia on May 15-18, 2023. Join us for the third edition!
Application deadline: Jan 27 (11:59 p.m. EST) 2023.
"Historically, with the study of the most convenient animal models —from the giant axon of the squid and the lobster's stomatogastric circuits to Aplysia's synapses and C. elegans' circuits — neuroscientists revealed some of the operating principles of the nervous system, which were then found to apply broadly across phyla. The third instalment of this meeting will once again bring together neuroscientists working on a broad diversity of animal models in an effort to compare circuits across phyla as a means to crack their function."

Hi! 👋
It's time for an #introduction here on #neuroscience mastodon.
I'm Hannah Haberkern and I study flies to learn more about how animals navigate. I'm especially interested in visual orientation and the role of plasticity in #navigation. Currently I'm a postdoc at HHMI Janelia in Vivek Jayaraman's lab.
I'll take this new start as an opportunity to start sharing a bit more #pigeon and #quilting content. Here's me with a semi-recent quilt finish, a quilt that's in progress, and my Boab.

Hi #ScienceMastodon. We, at #J_Cell_Sci, are a #community journal covering all areas of #cellbiology. We also host the microscopy community site @focalplane_jcs. Journal of Cell Science is led by Editor-in-Chief Michael Way & published by the not-for-profit @Co_Biologists.
We will toot about our content, including #research papers, #reviews, #interviews, charitable activities, and news from @focalplane_jcs.

Beautiful work by Omaya Dudin @DudinLab reminding us of the massive undersampling of diversity in modern functional #biology.
The first look at the #development of just one Ichthyosporeans (close relatives of animals) opens up completely new worlds that we could not have predicted from genomes only.
Check out this life-cycle video:

and there is a lot more diversity of life cycles and cleavage patterns across the group

"The controlled expression of one cellular feature -- the cilium -- was likely critical during early animal evolution. Two key transcription factors, RFX and FoxJ1, coordinate ciliogenesis in animals but are absent from the genomes of most other ciliated eukaryotes, raising the question of how the transcriptional regulation of ciliogenesis has evolved."

#Introduction to #ScienceMastodon
I am a #Cilia #Islet #Biologist and endocrinologist at WashU in St Louis.
#PrimaryCilia because it is the center of the cell and my world.
Unafraid to challenge convention and do difficult experiments (because we don’t know better).
Also #Microscopy because seeing is believing.

For neuroscientists attending #sfn22: don’t miss the poster by Mitya Chklovskii’s group describing the completion status of the whole brain #connectome of the fairy wasp #Megaphragma, of expected completion early in 2022. Find the poster tomorrow Monday morning, number 328.16 / YY35.
Mitya kindly shared the poster image publicly elsewhere.
This tiny #wasp is famous for being the size of a large paramecium (a unicellular organism) and for enucleating the vast majority of its central neurons while pupating. The adult has less that 10,000 neurons in its central brain yet it isn’t missing any organ or body part. See the paper that jumpstarted this effort:
