Robotic Spine Universe

Changelog

Newest first. Corrections to content are listed here as well as new features.

  1. All articles, shared caching and free licensing

    • 27 more sourced articles: 33 in all, covering the column, the cord, its pathways, reflexes, autonomic control, injury and neurotechnology
    • Five more flow diagrams (walking rhythm, bladder, breathing, brain–spine interface, BCI signal chain) and the pelvic incidence formula
    • Sourced pages for the filum terminale, interspinous ligament, alar ligaments, tectorial membrane, posterior spinal and segmental medullary arteries, and Rexed laminae
    • Shared page cache: in memory, Redis or Valkey across instances, and Next.js's filesystem cache; nginx and Docker setup for peak traffic
    • Free, non-commercial showcase: code MIT, content CC BY-NC-SA 4.0
    • Glossary grown to 46 terms; two new reading paths

  2. Learn section

    • Six articles at three depths (Overview, Student, Specialist), each paragraph cited
    • Formula registry with worked examples recomputed by the build
    • Flow diagrams for the corticospinal tract, dorsal columns, spinothalamic tract and two reflexes
    • Glossary and reading paths

  3. Structure pages

    • A page for every vertebra, disc, cord segment, spinal nerve and white-matter tract, plus sourced named structures
    • Model facts labelled as measured on one supine cadaver; anatomy quoted from its source

  4. Corrections

    • Reflex pathways now say exactly what the textbook states: the stretch reflex inhibits the antagonist through a spindle collateral, and the withdrawal reflex inhibits the triceps through a dorsal-horn interneuron
    • Root-exit rule and counts now cite the textbook sentences that state them
    • OpenStax attribution added to every page

  5. Pathways

    • Eleven tracts and reflex arcs routed through the body model and the cord cross-section

  6. Simulation lab and frontier

    • Neuron lab, signal journey, lesion explorer, alignment and load, BCI decoder, digital bridge and walking rhythm
    • Validation page with checks against published values
    • Frontier registry with evidence tiers and as-of dates
    • Variation page

  7. Body tab

    • Full skeleton, muscles, arteries, veins, organs and brain from BodyParts3D, with sourced connections to each spinal level

  8. Spine viewer and themes

    • 3D spine with both level systems and cord cross-sections
    • Auto, Light, Dark (true black) and Eye comfort themes; live motion with a pause control
