Spreading Activation

How one memory triggers another — just like your brain.

The coffee analogy

Think about coffee. Now your brain is activating: morning, productivity, that bug you fixed at 3am. You didn't choose to think about those things — the activation spread through connected nodes automatically.

BrainBase works the same way. When you mention "authentication", the graph activates "JWT", "session management", "that security decision from last week", "the user model". Connected knowledge rises to the surface.

Multi-hop activation

Activation doesn't stop at direct neighbors. Node A triggers B, B triggers C. The activation weakens with each hop but can reach surprisingly distant knowledge. This is how the brain makes connections you wouldn't think to search for.

Priming

Recently activated nodes are easier to reach. If you discussed "database optimization" yesterday, those nodes are still warm today. The brain is primed — retrieval is faster, context is richer.

Inhibition of Return

Already-visited paths get temporarily suppressed. This prevents the brain from getting stuck in loops and forces it to explore different connections. New pathways, new insights.

Pattern Completion

You mention half a concept, the brain fills in the rest. Mention "that React hook we discussed" — the brain activates the entire pattern: the specific hook, the component it was for, the bug it solved, the architectural decision behind it.
