Consciousness & Attention
- Theory 08 · Attention Trades Precision for Bias
Attention operates by trading sensory precision against prior bias, and the operating point is set by the ratio of expected reward to sensory noise, so the same cue can sharpen or bias perception depending on that ratio. - Theory 07 · Access Is a Timing Ratio
Whether a stimulus reaches consciousness is set by the ratio of recurrent processing time to the interval before the next stimulus, so identical stimuli can be seen or missed depending on timing rather than on strength. - Theory 09 · The Self Is Interoceptive Confidence
The sense of self is a model of the precision of interoceptive prediction rather than of body ownership, so manipulations that change interoceptive noise should change self-report more than manipulations of ownership.
Transplant & Immune Tolerance
- Theory 02 · Chronic Rejection Is a Shear Response
Chronic rejection is driven by the mismatch between the graft's design shear stress and the recipient's flow, so the disease is a remodelling response to a haemodynamic error rather than an antibody attack on the vessel wall. - Theory 01 · Acceptance Is a Local Ratio
Graft acceptance is set by the ratio of regulatory to effector T cells inside the graft rather than by systemic chimerism, so a systemically tolerant animal can still reject and a non-tolerant one can still accept. - Theory 03 · Xenograft Survival Is a Complement Ratio
The survival of a xenograft is set by the ratio of donor complement regulators to recipient complement activity rather than by antibody titre, so a lower-titre recipient can reject faster if its complement is more active.
Regenerative Biology
- Theory 06 · Regeneration Needs Nerves, Not Factors
Appendage regeneration requires a threshold in nerve density at the stump rather than a specific trophic factor, so denervation abolishes regeneration even when the factors are supplied exogenously. - Theory 04 · Regeneration Is a Ratio
Regenerative capacity is set by the ratio of progenitor pool to inflammatory load rather than by the size of the progenitor pool, so a tissue with many progenitors can fail to regenerate if inflammation consumes them. - Theory 05 · Scarring Needs Tension
Scarring is a mechanised default that regeneration overrides below a tension threshold, so reducing mechanical tension across a wound should shift healing from fibrosis to regeneration without changing the inflammatory environment.
