#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.

"These results have broad implications for biological processes regulated by membrane potential, particularly in contexts such as neuronal signaling, where condensate interactions with membranes may play a previously unrecognized regulatory role."

`We report that plasma concentrations of ubiquitin C-terminal hydrolase-L1 (UCH-L1) and neurofilament light (NfL) become exponentially higher from ages 2 to 85 in cross-sectional samples, serving as neuronal death/damage biomarkers across the lifespan.`

🧠 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 "

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.
