The Salahi Biological Brain Bridge and a Brain-First Framework for Neural Repair, Modular Organs and Human Longevity

The human brain can change its own wiring. After a stroke, practice can move control of a weak hand to surviving brain areas. In people who are blind from early life, the part of the brain normally used for sight takes part in reading Braille. Children who have had half of the brain removed to stop severe seizures can often still walk, talk and learn. This ability, called neural plasticity, is one of the best-established findings in brain science. This paper takes that proven fact as its foundation and builds a much larger proposal on top of it. Its central concept is the Salahi Biological Brain Bridge, called the Brain Bridge for short. The Brain Bridge is a planned system in which neural tissue grown from a person's own cells, called the companion tissue, is connected to that person's brain. The companion tissue would be trained to take part in a chosen brain function while the original tissue still works. It would then carry that function while the damaged area is repaired, and hand the function back as the repaired area learns it again. The whole process is set out in eight stages: Map, Grow, Connect, Teach, Hand Over, Repair, Hand Back and Release. The paper then joins the Brain Bridge to the author's earlier work on replaceable organs. The Bio-Synthetic Sleeve and Living Pouch describe living pockets that hold machines which can be swapped out. SINVAB describes how blood vessels, nerves and muscle could be built together. Together these form two linked tracks: keeping the body's organs working through repeated repair, and keeping the brain's functions, and the person, through repair. Every ability described here beyond neural plasticity itself is a concept waiting for evidence. The paper sets out a ladder of five levels of proof, from keeping tissue alive to keeping a person's memories and sense of self. It names the risks, lists the tests, and records the design on the public record under its author's name and date.
