03 / EDITORIAL READING
Separating which connections can change could protect prior learning even when neurons are shared.
04 / WHAT REMAINS UNKNOWN
The context signal was supplied externally in the model. Memory preservation in vivo remains to be tested.
05 / NEXT CHECK
Manipulate branch selection during new learning and distinguish effects on storage from effects on recall.
A hypothesis to keep honest
HYPOTHESIS · NOT YET TESTEDBranch selection during learning may protect old connections.
What would change our view: Reconsider the protective mechanism if prior memory persists after disrupting branch selection during learning.
A prospective test proposal, not a prediction score. A graph connection does not validate this hypothesis.
