"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."

#introduction

I think about how a collective of agents (animals, neurons, mathematical structures) can solve problems. Additionally, I am interested in what it means to produce a good model and understanding of something.

I am excited to be here to learn and discuss.

Hello world, it's time to do an ! I'm a neuroscientist (postdoc) currently based in Göttingen, Germany. I have broad interests in , including sensory coding, neural circuits, and sensorimotor transformations.

So far, I studied how the retina processes natural scenes using a combination of large-scale electrophysiology and computational modeling.

I'll be soon leaving the tidy entryway to the visual system to venture into understanding cortical processing during decision-making.

Just received another offer to sell @glossa to an unnamed 'publisher' from Singapore. Again made it clear that the journal cannot be sold, as stipulated in its Governance by-rules glossa-journal.org/site/govern Very important for #DiamondOpenAccess journals to make themselves impregnable to this sort of 'invitation'.

Mostly in order to practice the Mastodon interface, I'm going to reproduce one of my posts from the now-defunct Google+ service (on probability paradoxes, first posted Sep 11, 2014) as a thread here. 🧵

Please apply - this is a great program!

Hi it's me - hoping all of my great tweeps are here somewhere

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 cbd.sites.vib.be/en.

My favourite grasshopper photo moment: moulting sequence. 

An unusual observation in the wild: a pale-looking large grasshopper nymph, immobile, that started moulting with undulating, rhythmic motions. The head cuticle slowly detached as the new body propelled forward–giving it the appearance of having two heads. Half way through, a yellowjacket wasp attacked!

The wasp munched on the soft, unexpanded wings while the grasshopper helplessly continued its slow moulting procedure into its adult form. Left alive but not unscathed.

Ever looked at a grasshopper up close?

When approached, grasshoppers either jump and fly away–if I'm too fast–or remain very still, as if whispering a mantra "I am not here, you haven't seen me". Except this only works when the camouflage pattern matches their background. Not the case here!

Not all ant-butterfly associations are mutually beneficial. In the case of the Large Blue (Phengaris arion), this relationship has developed a sinister twist!

Large Blue caterpillars are adopted by red ants and carried back to the ants' nest. Once inside, however, the caterpillar turns parasite on its hosts and starts devouring ant larvae! 😱 Much like a Cuckoo, it fools the ants into thinking it is one of their own young, mimicking both their chemical scent and the calls made by a queen ant.

👋🏼 I’m Raghav Chhetri, a scientist at Rockefeller University in NYC. I like to follow cells, neurons, photons through the lens of custom microscopes. I’m broadly interested in developing and applying neuroimaging technologies to understand the brain. I feel strongly about current practices in scientific research and strive to make science open, accessible, and welcoming to minorities, historically marginalized, and societally disadvantaged groups.

"Within about a 48-hour period, a critical mass of scientists had gotten their bearings and Mastodon brio, and were finding each other. Even if Twitter pulls itself out of what looks like a possible death spiral, I can’t see us all ever going back."

Teaching Intro to Neurosci, I’m disappointed in how the textbook handles Mental Illness.
jblearning.com/catalog/product

In short, it does a disservice to behavioral interventions.

And it holds up the idea of a gene>mouse model>a drug as the path forward (which has never happened in that simple way and never will).

It lacks nuance and humility on this topic. Does any textbook/chapter do this better?
