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.

Questions are being raised about microplastics studies—here's what's solid science and what isn't

But a recent investigation by The Guardian suggests that some of these claims may be less robust than they first appeared.

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.

To flexibly organize thought, the brain makes use of space
MIT researchers tested their theory of spatial computing, which holds that the brain recruits and controls ad hoc groups of neurons for cognitive tasks by applying brain waves to patches of the cortex.

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.

Consensus AI: Why will The vOICe sensory substitution defeat Neuralink Blindsight and other brain implants for restoring vision? https://consensus.app/search/why-will-the-voice-sensory-substitution-defeat-neu/dWrnJDjIR9uP48YkWTX_Ag/

Why will The vOICe sensory substitution defeat Neuralink Blindsight and other brain implants for restoring vision? - Consensus
Restoring vision in blind individuals can be approached through invasive brain implants (like Neuralink or visual prostheses) or non-invasive sensory substitution devices (SSDs) such as The vOICe, which converts visual information into sound. Each method has distinct strengths and limitations. Current evidence suggests that sensory substitution devices like The vOICe offer unique advantages in safety, flexibility, and practical visual rehabilitation, but do not fully replicate natural vision.

Brain stimulation improves vision recovery after stroke
Scientists at EPFL have developed an innovative, non-invasive brain stimulation therapy to significantly improve visual function in stroke patients who have suffered vision loss following a stroke. The approach could offer a more efficient and faster way to regain visual function in such cases.
