Misplaced Neurons Reveal the Brain’s Adaptability
Can the brain keep working when its architecture changes?

One of the things that made organizing a lot easier with the GDC was a thing called "GDC in a box." It was a zip file with all kinds of resources. There was a directory structure, templates for all kinds of things like meetings and paperwork you had to file (for legal reasons) and "read me" files.
We had all kinds of support. There were people you could talk to who had been there. There were people you could call to walk through legal paperwork (taxes). Centralized orgs are vulnerable and easy to infiltrate. They're easy for states to shut down. But there are benefits to org structures.
I think it's possible to have the type of support we had with the GDC, but without the politics of an org (even the IWW). I hope this most recent essay has some of the same properties. I hope that it makes building something new, something no one has really imagined before, easier.
This whole project is something a bit different. It's a collective vision and collective project, from the ground up. Some of it has felt like a brain dump, just getting things that have been swimming around in my head down somewhere. But I hope this feels more like an invitation.
Everything thus far written is all useless unless people do things with it. Only from that point does it become a thing that lives, a thing with its own consciousness that can't be controlled by any individual human.
Tech billionaire cultists want to bring a new era of humanity with AGI. That is definitely not possible with LLMs, and may not be possible at all. But there is a super intelligence that is possible, though it's been constrained by capitalism: collective human intelligence.
The grand vision of the tech dystopians is that of the ultimate slave that can then enslave all humans on their behalf. I think we can build a humanity that can liberate itself from their grasp, crush their vision, and build for itself a world in which people will never be enslaved again. Not only do I think it's possible, I think it's necessary. I think there are only two choices: collective liberation or death.
And that's what I plan to write about next time to wrap this whole project up. Today things often feel impossible. But people talked about the Middle Ages as though they were the end of the world, and then everything changed in unimaginable ways. Everything can, and will, change again.
"The profit motive often is in conflict with the aims of art. We live in capitalism. Its power seems inescapable. So did the divine right of kings."

Parallel Neuron Groups in the Drosophila Brain

Abstract: The full connectome of an adult Drosophila enables a search for novel neural structures in the insect brain. I describe a new neural structure, called a Parallel Neuron Group (PNG). Two neurons are called parallel if they share a significant number of input neurons and output neurons. Most pairs of neurons in the Drosophila brain have very small parallel match. There are about twenty larger groups of neurons for which any pair of neurons in the group has a high match. These are the parallel groups. Parallel groups contain only about 1000 out of the 65,000 neurons in the brain, and have distinctive properties. There are groups in the right mushroom bodies, the antennal lobes, the lobula, and in two central neuropils (GNG and EB). Most parallel groups do not have lateral symmetry. A group usually has one major input neuron, which inputs to all the neurons in the group, and a small number of major output neurons. The major input and output neurons are laterally asymmetric. Parallel neuron groups present puzzles, such as: what does a group do, that could not be done by one larger neuron? Do all neurons in a group fire in synchrony, or do they perform different functions? Why are they laterally asymmetric? These may merit further investigation.

Allometric scaling of brain activity explained by avalanche criticality

arXiv:2512.10834v1 Announce Type: new
Abstract: Allometric scaling laws, such as Kleiber's law for metabolic rate, highlight how efficiency emerges with size across living systems. The brain, with its characteristic sublinear scaling of activity, has long posed a puzzle: why do larger brains operate with disproportionately lower firing rates? Here we show that this economy of scale is a universal outcome of avalanche dynamics. We derive analytical scaling laws directly from avalanche statistics, establishing that any system governed by critical avalanches must exhibit sublinear activity-size relations. This theoretical prediction is then verified in integrate-and-fire neuronal networks at criticality and in classical self-organized criticality models, demonstrating that the effect is not model-specific but generic. The predicted exponents align with experimental observations across mammal species, bridging dynamical criticality with the allometry of brain metabolism. Our results reveal avalanche criticality as a fundamental mechanism underlying Kleiber-like scaling in the brain.

Their findings may have implications for better understanding neurodegenerative diseases characterized by declining neurological or brain function, and even shed new light on issues with learning and memory.

Tiny sugars in the brain disrupt emotional circuits, fueling depression
Depression is a serious disorder that disrupts daily life through lethargy, sleep disturbance, and social withdrawal, and also increases the risk of suicide. The number of depression patients has steadily increased over the years, affecting more than 280 million people worldwide as of 2025. Now, researchers have uncovered a new pathological mechanism that could provide clues for the diagnosis and treatment of depression.

fly_larva: Drosophila larva brain (2023)
A complete synaptic map of the brain connectome of the larva of the fruit fly Drosophila melanogaster. Nodes are neurons, and edges are synaptic connections, traced individually from brain image sections using three-dimensional electron microscopy–based reconstruction. Node metadata include the neuron hempisphere, hemispherical homologue, cell type, annotations, and inferred cluster. Edge metadata include the type of interaction (`'aa'`,…

Wireless device ‘speaks’ to the brain with light
In a new leap for neurobiology and bioelectronics, Northwestern University scientists have developed a wireless device that uses light to send information directly to the brain — bypassing the body’s natural sensory pathways.

Astrocytes are superstars in the game of long-term memory
Why are we able to recall only some of our past experiences? A new study led by Jun Nagai at the RIKEN Center for Brain Science in Japan has an answer. Surprisingly, it turns out that the brain cells responsible for stabilizing memories aren't neurons. Rather, they are astrocytes, a type of glial cell that is usually thought of as a role player in the game of learning and memory.

Targeted ultrasound can shape the brain's reward-seeking mechanisms
The nucleus accumbens is a tiny element of the human brain triggered when we experience something enjoyable, and used to help us learn behaviors that lead to rewards. A new study has shown for the first time that its influence on human behavior can be altered using transcranial ultrasound stimulation (TUS).

Prototype device restores lost smell by teaching the brain to feel odors
There is new hope for people who have lost their smell. Scientists have successfully tested a breakthrough device that lets people detect the presence of certain odors. This innovative system helps them "smell" again by translating odors into feelings (like touch) inside the nose.
