Does transplanted neural tissue help surviving circuits, take over missing functions, or both?
04 / WHAT REMAINS UNKNOWN
This was not adult injury repair. Gait and maze signals do not establish improvement over ungrafted mice, and graft activity has not been shown necessary for the behaviors.
05 / NEXT CHECK
Manipulate graft activity during specific tasks to distinguish modulation of host circuits from information processing.
A hypothesis to keep honest
HYPOTHESIS · NOT YET TESTEDFunctional support may depend on the combination of graft and surviving host circuits, not graft survival alone.
What would change our view: If performance persists when graft activity is silenced, consider support of host development or reorganization.
A prospective test proposal, not a prediction score. A graph connection does not validate this hypothesis.
