Cells and biology

Every character in Arborwake stands for a real kind of brain cell. The game borrows what these cells do, such as clearing debris, wrapping axons or calming signals, and turns it into play. It never claims that a game rule is a real measurement or a medical fact. See Science guardrails.

Cell types#

• AstrocyteStar-shaped support cells; in Arborwake they are anchored residents whose help is spatial and finite.In the alpha
• Border-associated macrophageImmune cells that live at the brain's borders rather than inside the tissue; Bram is one, and they are not microglia or invaders.Approved
• MicrogliaThe brain's resident immune cells; in Arborwake, the Ranger and every recruitable companion are microglia.In the alpha
• MonocyteBlood immune cells that, in some rodent stress models, are recruited to the brain's vessel walls; in Arborwake they appear only in model-labelled Vessel Margins rooms.In the alpha
• NeuronNerve cells that carry signals; in Arborwake they are rooted gold residents whose pulses the player learns to read and must never lose.In the alpha
• OligodendrocyteThe cells that wrap axons in myelin; in Arborwake they are anchored and only extend, and only they can repair the Quiet District road.In the alpha
• Oligodendrocyte precursor cellThe young cells that can mature into new oligodendrocytes; in the Quiet Tracts they mature in place and wrap by extension.In the alpha
• PericyteCells wrapped around small blood vessels; in Arborwake, Vessa is a pericyte who reads the vessel border.Approved

The science of the story#

• AAcute brain injuryThe science behind the Act V finale, a sudden focal mechanical injury that starts a different immune process from stress.Approved
• MMyelin, demyelination and repairThe science behind the Quiet District's optional road repair, kept separate from the stress story on purpose.Approved
• SScience guardrailsThe rules that keep Arborwake's biology honest; its classes and abilities are fictional mechanics, not clinical claims.Approved
• SSleep and stress researchResearch on sleep, phone use and accidents that once informed a human "owner" storyline; the user excluded that storyline, so sleep is background only.Retired
• SStress-associated neuroinflammationThe research theme behind Arborwake's central story, presented as model-specific and context-dependent, never as a single stress meter.Approved
• SStress-associated neurovascular relayThe rodent finding behind Act II's Relay scenes, in which microglia, blood monocytes and the vessel lining pass an inflammatory signal, and its necessary counter-example.Approved
