A new paper uses a deep neural network and biophysical models to compare, and quantify, the different functional complexity of human and rat neurons, showing that individual human neurons carry out more complex information processing than rat neurons. The authors suggest that neuronal complexity has coevolved with connectivity structure.

🧠 What can a single neuron compute?
A new #bioRxiv #preprint introduces #TwinProp, using a differentiable digital twin to optimize synaptic strengths and locations in a detailed layer 5 #pyramidal #CellModel. One #neuron classified images and speech and even solved 10-bit parity with 91% accuracy. The key: distributed #dendritic nonlinearities, especially #NMDA-dependent integration:

`Our results point to these neurons being an important orchestrator of neural and vascular dynamics, as loss of these neurons causes desynchronization between hemispheres of both neural and vascular signals, as well as altered responses to sensory stimulation.`

Ez lett a végeredmény.
Nem jó, de nem is tragikus.
Az biztos, hogy a legutóbbi Claude által készítettnél informatívabb, edukatívabb, viszont vizuálisan eléggé katasztrófa és sok gombja nem is teljesen működik.Viszont, sokkal jobban tanul, nem fagy ki, de amennyire nyomorodott, nem látni nagyon semmit belőle.
De, ez azzal az alap prompttal készül, amelyiket mindegyik modell megkap a teszt során. Ahhoz képest viszont jó!
Most akkor kicsit finomítok rajta, mert lehet ebből tényleg lehet személetes oktató anyag a végén. (Mindegyiknél ezt mondom, aztán néhány kör után megy a kukába mégis.)

Kívácsi vagyok!
De eddig ez a GPT-5.5 valami nagyon... huhh...!
Előre blikkre nálam tényleg jobban teljesít, mint a Claude Opus-4.7!
Most kipróbáltatom vele a "szokásos" edukatív neuronhálós promptomat. Igazából, nálam ez az egyik összehasonlítási alapom.
Várom mi lesz belőle! Dolgozik vele rendesen, már több, mint tíz perce.

`Here, we demonstrate artificial neurons that not only closely emulate biological neurons in functions but also match their parameters in key aspects such as signal amplitude, spiking energy, temporal features, and frequency response. Moreover, these artificial neurons can be modulated by extracellular chemical species in a manner consistent with neuromodulation in biological neurons.`

RAG на PHP + Qdrant: быстрый MVP для внутренней базы знаний
RAG на PHP - звучит непривычно. Делюсь опытом построения чат-бота для поиска по внутренней базе документов: Symfony, Qdrant с гибридным поиском, YandexGPT для embedding и генерации ответов. Внутри — готовый код, подводные камни чанкинга и советы, которые сэкономят вам время.

#ITByte: An #Artificial #Neuron, or node, is a basic computational unit in an artificial neural network (ANN) that mimics a biological neuron.
It receives inputs, multiplies them by associated weights, adds a bias, applies an activation function to the weighted sum, and produces an output.

🧠 New preprint by Tilbury et al: Characterizing #NeuronalPopulation geometry with #AI equation discovery
The approach generates & evaluates 100s of candidate equations, finding "peaky" non-Gaussian tuning functions whose Fourier structure matches power-law dimensionality observed in real #V1 pops. Links shape of single-#neuron tuning to #PopulationLevel geometry using both data fits & analytical derivations.

An interesting essay by Oliver Hobert on 'Paraneurons':
"unifying sensory receptors
located on external or internal epithelial
cells feeding into the nervous system,
as well as effector cells of the nervous
system that respond to neuronal
stimuli by releasing hormonal cues "https://doi.org/10.1016/j.cub.2025.09.072

should by CC BY but seems still paywalled, so here is the pdf:

Собираем простейшую RAG-систему на PHP с фреймворком Neuron AI за вечер
RAG (Retrieval-Augmented Generation или генерация, дополненная поиском) - это метод искусственного интеллекта, сочетающий генеративную большую языковую модель (LLM) с внешней базой знаний для создания более точных, контекстно-зависимых и актуальных ответов. Принцип его работы заключается в том, что сначала извлекается релевантная информация из набора документов или источников данных, а затем эта информация передается в LLM для формирования окончательного ответа. Этот процесс позволяет модели выдавать более точные ответы, менее подверженные “галлюцинациям”, и ее можно обновлять без дорогостоящего переобучения. Сегодня мы разберёмся, как собрать базовую RAG-систему на PHP (да, да, не надо удивляться) с помощью фреймворка Neuron AI . Это будет наш маленький proof-of-concept - минимально работающий, но вполне реальный пример. Ну что, начнём генерацию?

🧬 The Molecular Tragedy of Neurodegeneration
When proteins misfold, they corrupt others into their twisted shape. This cascade creates Alzheimer's, Parkinson's, and ALS. Specific neurons fall while others persist because cellular architecture and metabolic demands determine vulnerability.
