定义水平和垂直联想记忆概念。垂直联想内存涉及分块：新（先前空闲）节点的规范来表示旧（绑定）节点的组合。分块被认为是语义记忆、条件反射配置和认知（与刺激-反应相反）学习的基础。大脑皮层有分块的能力，但是海马体（边缘）唤醒系统在分块过程中起着关键作用，它通过不同的启动（部分激活）自由神经元，而不是束缚神经元。绑定一个神经元会产生负加速抑制其与海马体唤醒系统的连接，通过保护新绑定的神经元不受漫反射海马体输入的影响来巩固记忆，从而延缓遗忘。海马体唤醒系统的破坏会产生失忆症，即无法进行新的组块（认知学习）——顺行性失忆症——以及无法检索最近指定的组块——逆行性失忆症。（106 ref）（PsycINFO Database Record (c) 2016 APA，版权所有）
Defined horizontal vs vertical associative memory concepts. Vertical associative memory involves chunking: the specifications of new (previously free) nodes to represent combinations of old (bound) nodes. Chunking is considered to be the basis of semantic memory, configuring in conditioning, and cognitive (as opposed to stimulus–response) learning. The cortex has the capacity for chunking, but the hippocampal (limbic) arousal system plays a critical role in the chunking process by differentially priming (partially activating) free, as opposed to bound, neurons. Binding a neuron produces negatively accelerated repression of its connections to the hippocampal arousal system, consolidating the memory by protecting the newly bound neuron from diffuse hippocampal input and thus retarding forgetting. Disruption of the hippocampal arousal system produces the amnesic syndrome of an inability to do new chunking (cognitive learning)—anterograde amnesia—and an inability to retrieve recently specified chunks—retrograde amnesia.(106 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
