Those doctors would still not be able to improve school performance of the kids with learning disabilities and they would still not be able to prevent cognitive impairment and loss of memory in older adults because at this point we don't really understand enough about learning To know which neurons and synapses within a circuit would need to be tinkered with.

他恐怕还是改变不了有学习障碍的孩子们的表现,阻挡不了老年人的认知功能损害和记忆力的衰退,因为我们对这一学科的确知之甚少,不知道知道回路中的到底是哪些神经元和神经突触需要修复。
