ABSTRACT 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.

一种速度精确的自持头部方向细胞路径整合模型，无需反复激励

摘要 头部方向 (HD) 系统在同心参考系中发出 HD 信号。该系统能够根据有关自运动的内部衍生信息更新射击，这一过程称为路径整合。特别令人感兴趣的是路径集成如何保持真正的 HD 和内部表示的 HD 之间的一致性。在这里，我们提出了一个自我维持的两层模型，能够自组织，产生极其准确的路径整合。讨论了这项工作对未来 HD 系统路径集成研究的影响。
