The head direction (HD) system signals HD in an allocentric frame of reference. The system is able to update firing based on internally derived information about self-motion, a process known as path integration. Of particular interest is how path integration might maintain concordance between true HD and internally represented HD. Here we present a self-sustaining two-layer model, capable of self-organizing, which produces extremely accurate path integration. The implications of this work for future investigations of HD system path integration are discussed.
头部方向 (HD) 系统以一种以自我为中心的参考系来表示 HD。该系统能够根据关于自身运动的内部推导信息来更新其发射活动，这个过程被称为路径整合。特别有趣的是，路径整合如何保持真实 HD 和内部表示的 HD 之间的一致性。在这里，我们提出了一个能够自我组织的自维持两层模型，它能够产生极其准确的路径整合。本文讨论了这项工作对未来研究 HD 系统路径整合的意义。
