📰 "Multimodal social context modulates behavior in larval Drosophila"

#Drosophila #Behaviour #Sensory

bioRxiv · Multimodal social context modulates behavior in larval DrosophilaAll animals need to navigate and make decisions in social environments. They influence each other's behavior, but how important this is and how they process and represent social information in their brain is less well understood. This includes fruit flies and fly larvae, which are usually not known as social insects. Using a Drosophila larva assay with reduced stimulation, we found that larval groups show enhanced dispersal and distance from each other in the absence of food. This social context-dependent modulation overrides responses to other external sensory cues and is shaped by developmental social experience. Leveraging the genetic toolbox available in Drosophila , we find that different sensory modalities are required for normal social context modulation. Our results show that even less social animals like fly larvae are affected by conspecifics and that they recognize each other through multimodal sensory cues. This study provides a tractable system for future dissection of the neural circuit mechanisms underlying social interactions. ### Competing Interest Statement The authors have declared no competing interest.

📰 "The tardigrade as an emerging model organism for systems neuroscience"

#Drosophila #Behaviour #Q-Bio.Nc #Genomics

arXiv.orgThe tardigrade as an emerging model organism for systems neuroscienceWe present the case for developing the tardigrade (Hypsibius exemplaris) into a model organism for systems neuroscience. These microscopic, transparent animals (~300-500 microns) are among the smallest known to possess both limbs (eight) and eyes (two), with a nervous system of only a few hundred neurons organized into a multi-lobed brain, ventral nerve cord, and a series of ganglia along the body. Despite their neuroanatomical simplicity, tardigrades exhibit complex behaviors, including multi-limbed walking gaits, individual limb grasping, phototaxis, and transitions between active and dormant states. These behaviors position tardigrades as a uniquely powerful system for addressing certain fundamental questions in systems neuroscience, such as: How do nervous systems coordinate multi-limbed behaviors? How are top-down and bottom-up motor control systems integrated? How is stereovision-guided navigation implemented? What mechanisms underlie neural resilience and recovery during environmental stress? We review current knowledge of tardigrade neuroanatomy, behavior, and genomics, and we identify opportunities and challenges for leveraging their unique biology. We propose developing essential neuroscientific tools for tardigrades, including genetic engineering and live neuroimaging, alongside behavioral assays linking neural activity to outputs. Leveraging their evolutionary ties to Caenorhabditis elegans and Drosophila melanogaster, we can adapt existing toolkits to accelerate tardigrade research - providing a bridge between simpler invertebrate systems and more complex neural architectures.

@freemo @messaroundmarx There are 2 quotes here.
I assume it's the 2nd quote mostly about authoritarianism that is mostly the focus...

...which, if so, would you consider authority or authoritarianism as an uncaring (or almost financially-only caring) Bank and State Authority as the kind of dictator(s) or de-facto equivalent (i.e. without you totally using Bank or State then you are a mere nothing deliberately made increasingly conditional, whether they declare themselves as this or that political label.

Those two (or just for the purposes of this reply) are sole rulers and sources of life (or monopoly of it) and soon imprisoning people for non-conforming reasons (more examples of kangeroo #courts / #juries asked to #ignore evidence / terrorism chargers used on Twitter / Mastodon style social people silences and in jail / mothers arrested fpr speaking etc)...

So theoretically or de-facto would you agree Modern #Capitalism (or just today's type of actions and non-action of Banks 🏦 and State 👮 (whatever we call their actions as) is requiring these two authorities and not just the softer or neutral types of Capitalism.

The increasing #ultimatum and #conditional demanding #conforming to (or take it or leave life if you want) makes increasingly everything #illegal or incompatible by default and today's kind of Capitalism is more #punishment orientated...

Capitalism here as a constantly changing or added #restriction / #redefinition which is why we can not just focus on #labels like Authoritarianism but the #behaviour and track #record / #history, as well as what they #finance (#war), how they have things failed constantly in echange for profit / power etc etc, that contribute to similar things...

As part of constant systematic pattern (whatever we call that) and even considering people being #ignorant also (yes), but definitely no change to that model of #business as usual. Namely #tax, #territorial #aggression etc.

And on the other side more positive to humans, today it's hardly about #communication between #state and people, giving power to people, talking about well-being of humans, which I'd include as part of what makes it "Authoritarian style" behaviour also when it's without those components and considerations... would you agree?

Happy New Year by the way :)
