Wow this was interesting to see. I bought synapse.town and started setting up mastodon there, will post an update when it's ready!

@Excuse_haver brains.slime would be fun! Whoever decides domain extensions should definitely consider .slime and .sludge in the next standard

#Introduction post:

Hi! I'm Alyssa MacKenzie. My pronouns are she/her/they. I'm a non-binary trans woman, activist, LGBTQ+ media consultant, VERY active in my community & live in Orlando, FL.

I'm prominent in the trans community and on social media, mainly for being positive, supportive, yet fiercely protective of trans people and the entire LGBTQ+ community. I've been featured in many newspapers throughout the United States, am a former Field Organizer for the Human Rights Campaign and advocate for pro-equality candidates who will help advance trans liberation.

My contact info is in my profile, and you'll likely see my posts floating around on Fridays, as I typically do 'Trans Appreciation Friday', where all trans/non-binary people are welcome to participate, telling us their name, pronouns, a bit about them and posting a pic, if they feel comfortable.

I'm happy to be here. Please feel free to say hello any time! I'm a friend, a resource and will help in any way I can.

Most of my outdoor ferns are starting to die back for winter, but indoors, this Staghorn Fern brings me joy.

Some recent work suggests that these ferns may be on the cusp of eusociality. They grow on tree with overlapping generations of adult plants in a colony. Some plants specialise in leaf-litter collection and reproduction, and some in water-storage. Not quite an ant or a mole rat, but getting there... doi.org/10.1002/ecy.3373 #ferns #FernFriday #Platycerium #StaghornFern

Can any point me to books or resources about the use of physical models in scientific discovery? (I'm thinking of like how Watson and Crick played around with metal plates to make a double helix, etc)

@aeble That would be a great name, but it's already taken sadly... The ones above are still available

What's a good name for themed mastodon server?

Are people really not posting about the awful Ph.D. salaries on here? Or is the search bar just wonky?

Either way, here is a reminder that Biology Ph.D. students are not expected to be able to afford basic living costs.

As the largest living #reptile, the saltwater #crocodile can reach 23ft and 2200lbs. With 66 teeth up to 5" long and the world's strongest bite, this modern #megafauna is a formidable predator that feeds on anything. It usually lurks in brackish waters, lunging onto land to capture prey including buffalo, sharks, and humans.
Unlike most reptiles, crocodiles protect their young. Mothers stay with eggs, carry hatchlings to water in their mouths, and care for them for months after hatching.

@freemo Oh wow, I didn't realize that the cost for storing and searching past posts would be so high! It's good to know this in advance.

Also that's a great point about listening to people but not pleasing everyone. I'll keep that in mind as well!

@freemo Thank you for the reply! The second point about longer limit is definitely from me being spoiled here and seeing how much nicer the discussion can be.

I'm curious about two things:
1) If you can share, how much does it cost to run qoto.org per month? How big of a machine do you use?
It helps a lot to see cost breakdown from other servers for planning.
2) Do you have advice on setting up a welcoming culture?

Seems like a lot of the science/humanities/academia instances are closed or getting really big. I'm thinking of making my own instance. Some aspects I'd like it to have:
* domain blocks for hateful sites
* longer text limit to promote deeper discussion (maybe 20k characters)
* latest mastodon+glitch ( glitch-soc.github.io/docs/ ) with all the nice features
* culture welcoming especially to people identifying with LGBTQIA+ and PoC

I looked into the technical and financial aspects and I can do this!

Would anyone be interested in this? Any suggestions on the last point?

It was three years ago that I started to see the shadow animals.

@ichoran @albertcardona Ah yes that's a good point! Yes, perhaps I was overzealous in comparing GCaMP to BOLD. It's more like doing widefield imaging with GCaMP6s.. Even in flies it could be interesting to do this, although there it would be more powerful complemented with genetics and anatomy. Sophie Aimon did some work along these lines, although this whole subfield is still early.

@csdashm @albertcardona Ah, I wanted to add also that I totally agree with you about knowing much more details about the structure of fly brain and nerve cord as well as mouse cortex, yet still grasping at a nice explanation of how it all works.

I have found the integration of connectomics with functional imaging in central complex so satisfying to watch unfold. Certainly you couldn't do this with fMRI! The genetic targeting, spatial resolution of imaging, and connectomics are just not there at this time.

Still in other places my impression is that the strangeness and complexity of the connectome is truly humbling. IMO, we need better constraints from functional studies and from behavior. Then again, my research is in quantifying behavior so I'm probably biased there haha.

@csdashm @albertcardona
To expand on the "cognitive fingerprint" comment, cognitive neuroscientists often treat the pattern of neural activations evoked by a stimulus or mental concept as a "fingerprint" for that concept.

For instance, I remember going to a talk by a social scientist where she showed similarities in the neural activity between two tasks: reading about companies interacting or reading about people interacting. In contrast, reading about objects interacting produced different neural responses. To see whether corporations are seen as people or objects, the specific areas activated are not important, but the similarity of the patterns is. The activation pattern is treated as a fingerprint: the grooves in the finger matter only in that they consistently identify the finger's owner.

Treating the neural activity as a fingerprint and inferring mental concepts is a big part of cognitive neuroscience. However, this can frustrate biologists who care about the specifics of the neural computations. What's more, in systems neuroscience, my impression is that behaviorism rules and it frowns upon inferences about the psychology of non-human animals. Thus the gap is even bigger!

So here's a cool thing. These little devices (magnets that attach to the back of your knife) keep delicate slices of, well, whatever you’re slicing, from sticking to the knife-back while you’re working. Garlic is a good test….

@albertcardona

I'll note that I think part of the confusion is a cultural one. Having gone from a cognitive neuroscience fMRI/ECoG lab to a drosophila neuroscience lab, I feel there is a disconnect between the goals and methods between the two fields. The drosophila neuroscientists (unfairly) dismiss cognitive neuroscience as not rigorous enough, whereas the cognitive neuroscientists (unfairly) dismiss work on drosophila as they see flies as "too simple".

I think this reflects a larger gap that I've seen of neuroscientists approaching the brain from a cognitive versus biological angle and how this leads to them to pursuing different goals using different methods. Cognitive scientists are often looking at neuroscience for fingerprints that can clarify cognitive concepts, whereas biologists often look at neuroscience trying to understand natural computation and biological processes connecting to the rest of the body.
