模式是集成和组织较低级别表示的较高级别的知识结构。作为内部模板，图式是根据事件如何被感知、解释和记忆而形成的。虽然这些高级单位被认为在我们的日常生活中起着重要的作用，但图式形成和使用的神经基础和机制在很大程度上仍然是未知的。重要的是要阐明大脑如何构建和维持这些更高层次的单位。为了研究图式可能的神经基础，我们概括了以前的工作，并讨论了他们的发现有关的图式作为大脑模板。我们特别关注低β/纺锤波振荡，这被认为是图式的关键组成部分，并提出大脑模板是由三重神经振荡实现的，即δ，低β/纺锤波和涟漪振荡。
Schemas are higher-level knowledge structures that integrate and organise lower-level representations. As internal templates, schemas are formed according to how events are perceived, interpreted and remembered. Although these higher-level units are assumed to play a fundamental role in our daily life from an early age, the neuronal basis and mechanisms of schema formation and use remain largely unknown. It is important to elucidate how the brain constructs and maintains these higher-level units. In order to examine the possible neural underpinnings of schema, we recapitulate previous work and discuss their findings related to schemas as the brain template. We specifically focused on low beta/spindle oscillations, which are assumed to be the key components of schemas, and propose that the brain template is implemented with a triplet of neural oscillations, that is delta, low beta/spindle and ripple oscillations.
