A tad late for , but I submitted a set of my arthropod Lego designs to @LEGOIdeas!

My set idea "Arthropod Model Organisms" features models for a fruit fly, amphipod crustacean, red flour beetle, and two-spotted cricket.

I wanted to share this Call for Vision Statements for New Neuroscience Collaborations funded by the Simons Foundation in case someone finds it useful. This is significant funding to tackle risky research ideas. Scientists can be based anywhere in the world. Share with people you know!

#Introduction
Hi all, I'm a spatial cognition postdoctoral researcher and will post about rats (like these), #PlaceCells (yes it's a new hashtag) and other cool things that the #Hippocampus does, as well as random stuff.

If I have bad habits from "that other site", please help me correct them, and as a Mastodon newbie, do send me your tips or tutorials!

PS: do rats need content warning?

Hi all, instead of a re- #introduction after moving instances, I'd like to introduce you to my graduate student Peter Salvino, who passed away under tragic circumstances last week.

Because of his way too early passing, most of you didn't get to know him. So I wanted to make sure my #neuroscience community knows how brilliant and kind a scientist he was. Peter wore many hats in the lab. Being my very first student, he built with me, and knew the ins and outs of every bit of hardware and software. He was also a masterful engineer and inventor, and had a keen scientific mind. He knew what the big questions in the field were and was completely fearless in going after them. We will slowly publish all his great contributions, so you will read his name again.

Most importantly, he was so generous to his lab mates. He helped every single person in the lab, with such selflessness and genuine humbleness. He was really loved by all of us. This is such a huge loss to our field. He was destined to greatness.

Peter's family has set up a GoFundMe campaign to help support research similar to his at Northwestern. They welcome any contributions to honor the memory of this amazing human being.

IMHO the most complete and remarkable site for #womeninscience #womeninSTEM. 1432 portraits !

An extraordinary source of information. Only in spanish but very easy to browse and understand with an online translator (such as DeepL translate)

Such a beauty 🤩 Looking at one of the earliest #Zeiss microscopes 🔬 with #ErnstAbbe’s equation stating the #diffractionlimit in the background at the Museum of #Optics in Oberkochen - It is always fascinating to learn about the history of #science & #technology - #superresolution #microscopy #photonics 👉 zeiss.com/corporate/int/about-

Great speaker line-up and an awesome location!

Going forward, #DeepLabCut updates will come via medium (and GitHub of course), but not the bird. This is sad, as the science Twitter community, I believe, was so important in getting out the word early on our very first code release and paper. But, it’s not okay anymore 💔

📣🚨To get the latest updates on our code releases going forward, please see our medium blog deeplabcut.medium.com and all resources linked on our homepage: DeepLabCut.org - take care #deeplabcutters 🙏🏼💜

This morning three #chimpanzees from Furuvik Zoo escaped, which triggered a massive man(chimp)hunt, resulting in the three chimps being shot to death. In the ensuing chaos, a fourth chimp managed to escape, which after a long search was also killed. During all this, a fifth chimp also managed to escape! 🤯 Luckily, the fifth chimp returned to its cage/prison. We really should not keep animals in zoos, in particular not advanced primates.

Stages of getting into a new research thing

1. No one has thought of this
2. Oh, some people have, but it’s not exactly the same
3. Oh, it’s exactly the same
4. OMG, everyone already knows about this, but they all call it something different

NIT: an open-source tool for information theoretic analysis of neural population data

Information theory provides a popular and principled framework for the analysis of neural data. It allows to uncover in an assumption-free way how neurons encode and transmit information, capturing both linear and non-linear coding mechanisms and including the information carried by interactions of any order. To facilitate its application, here we present Neuroscience Information Toolbox (NIT), a new toolbox for the accurate information theoretical analysis of neural data. NIT contains widely used tools such as limited sampling bias corrections and discretization of neural probabilities for the calculation of stimulus coding in low-dimensional representation of neural activity (e.g. Local Field Potentials or the activity of small neural population).Importantly, it adds a range of recent tools for quantifying information encoding by large populations of neurons or brain areas, for the directed transmission of information between neurons or areas, and for the calculation of Partial Information Decompositions to quantify the behavioral relevance of neural information and the synergy and redundancy among neurons and brain areas. Further, because information theoretic algorithms have been previously validated mainly with electrophysiological recordings, here we used realistic simulations and analysis of real data to study how to optimally apply information theory to the analysis of two-photon calcium imaging data, which are particularly challenging due to their lower signal-to-noise and temporal resolution. We also included algorithms (based on parametric and non-parametric copulas) to compute robustly information specifically with analog signals such as calcium traces. We provide indications on how to best process calcium imaging traces and to apply NIT depending on the type of calcium indicator, imaging frame rate and firing rate levels. In sum, NIT provides a toolbox for the comprehensive and effective information theoretic analysis of all kinds of neural data, including calcium imaging. ### Competing Interest Statement The authors have declared no competing interest.

What's up with the crow?

Like us, crows are highly intelligent ecological generalists that make a living not by executing simple fixed action patterns, but rather by learning about their environments and figuring out how to exploit them.

This bird has discovered that a metal bracket on a railing is precisely the right size and shape to hold a mussel while cracking it open.

How cool is that: a study on how fungal parasites take over the brain of the fruit fly #Drosophila.The authors report that the invasion of the brain by the fungus, breaking the blood-brain barrier, enables the summiting behaviour, triggered by factors in the hemolymph, and experimentally test this.

And we get to comment before the Americans wake up!

Weeks after I did a dual circuit tracing surgery, we gathered around a computer to see imaging results. Marveled at the beauty of the brain slice image: First result, which we further validated over time and with channelrhodopsin-assisted circuit mapping.

Anterior thalamus and claustrum project precisely to certain layers of the retrosplenial cortex: suggests mechanisms of how fear vs head direction is processed.

I’m wondering if y’all can help me build a community of trans people of colour on the tag #TransPOC as i miss the wonderful people i knew on a different animal themed app.
After seeing reports of racism and bad moderation I guess i’m just trying to find my people. Boosts very welcome.
