Fig. 1: Stability-plasticity dilemma and proposed neural solution.
From: Domain-specific schema reuse supports flexible learning to learn in the primate brain
a Illustration of the stability–plasticity dilemma, highlighting the balance between reusing existing knowledge (schemas) and the need for flexible adaptation. For example, individuals trained in one racquet sport, such as tennis, can often learn related sports like badminton or table tennis more efficiently, suggesting the transfer of stable motor schemas across contexts with variable demands. b Hypothesized neural solution: domain-specific NCS are preserved to maintain core task-relevant knowledge, while near-orthogonal neural subspaces allow flexible adaptation to task changes without disrupting the stable representations.
