The important bridge is discrepancy-driven updating, not a claim that one chemical simply encodes pleasure or that biological learning is identical to a software algorithm. ## Backlinks - [[wiki/Schedule and Loop|Schedule and Loop]] - [[articles/Schedule and Loop|Schedule and Loop]] ## Related Work in the Corpus <!-- BEGIN HUMANIZED CORPUS ROUTES 2026-09-11 --> - In [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]], **FlyWire: Whole-Brain Completeness at Insect Scale** provides the narrative context for **Dopamine**: Tools developed include Codex (Connectome Data Explorer)—an open-access web interface enabling anyone with internet access to navigate neurons and synaptic pathways without downloading massive datasets, already used by over… <!-- END HUMANIZED CORPUS ROUTES 2026-09-11 -->
