CORE DEFINITION

A hypothesis that there exists a specific neuron in the brain that activates only when you see your grandmother. It represents a "highly specific" encoding method.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Single-point dependency risk. If there is a "grandmother cell" type person in your system (or team) (only they understand the core business), once this neuron (person) dies, your cognition of "grandmother" collapses. Pursue distributed encoding rather than single-point encoding.

anchor

Anchor fast decisions

A compromise in the 'grandmother cell' debate: a single concept (like grandmother) is not encoded by a single neuron, but by a group of distributed neurons 'cell assembly' that collectively represent it, combining specificity and redundancy.
