The brain is not just a sponge of neurons, but a system of layers, each of which does its job. In cognitive sciences, the term "brain stack" is not a common or formal term. It's more metaphor or popularizing image, used by publicists, popular scientists, futurists or authors who explain complex things in simple words (for example, in books about neurointerfaces, transhumanism or artificial intelligence).
The brain has:
- Physical level <TAG1> neurons, electrical impulses, biochemistry.
- Sensory level <TAG1> vision, hearing, touch, etc.
- Emotional level <TAG1> limbic system, instincts, fear, joy.
- Cognitive level <TAG1> thinking, language, logic.
- Reflexive level <TAG1> self-awareness, self-image.
It's all together — as a stack in IT: from low-level signals to an "interface" through which you think about your own thoughts (metacognition).
Artificial intelligence — also has a stack, only software.
In AI, during the response, it is formed temporary context stack:
- tokens (words, signs),
- conversation history,
- intermediate representations ("I've already talked about it"),
- response-forming logic,
- text generation — one word at a time forward.
But there is a difference:AI has no real emotional memory chi physical experience. In the brain —, emotions can overwrite logic. In AI —, everything is linear and deterministic (so far ̄\_( ⁇ )_/ ̄).
So when you're tired and can't get together — is the top layer of your brain stack hangs, like a bug in a operative. You can "restart": rest, eat, change the focus of attention.
The term "brain stack" was first seen in a book about design patterns by the refactoring guru (google). The book can be bought online in digital version. There's EPUB, PDF, etc.
