I would say that artificial neuron nets try to mimic real neurons, they were inspired by them. But there are a lot of differences between them. I studied artificial intelligence, so my experience is mainly with the artificial neurons. But from my limited knowledge, the real neural nets have no structure (like layers), have binary inputs and outputs (when activity on the inputs are large enough, the neuron emits a signal) and every day bunch of neurons die, which leads to restructurizing of the network. Also from what I remember, short time memory is “saved” as cycling neural activities and during sleep the information is stored into neurons proteins and become long time memory. However, modern artificial networks (modern means last 40 years) are usually organized into layers whose struktuře is fixed and have inputs and outputs as real numbers. It’s true that the context is needed for modern LLMs that use decoder-only architecture (which are most of them). But the context can be viewed as a memory itself in the process of generation since for each new token new neurons are added to the net. There are also techniques like Low Rank Adaptation (LoRA) that are used for quick and effective fine-tuning of neural networks. I think these techniques are used to train the specialized agents or to specialize a chatbot for a user. I even used this tevhnique to train my own LLM from an existing one that I wouldn’t be able to train otherwise due to GPU memory constraints.

TLDR: I think the difference between real and artificial neuron nets is too huge for memory to have the same meaning in both.
