在过去的十年中，有助于方向感的神经结构的轮廓已经开始出现。一些研究揭示了前庭输入和视觉输入对头部方向表征的影响。在本文中，一个模型，制定的头部方向系统的神经机制。该模型由简单的成分组成，只依赖于连接特异性、吸引子动力学、赫布学习和S形非线性，但它的行为方式很复杂，与真实的头部方向细胞的大多数观察特性一致。此外，它还提出了一些预测，这些预测应该可以通过合理简单的实验来检验。
In the last decade the outlines of the neural structures subserving the sense of direction have begun to emerge. Several investigations have shed light on the effects of vestibular input and visual input on the head direction representation. In this paper, a model is formulated of the neural mechanisms underlying the head direction system. The model is built out of simple ingredients, depending on nothing more complicated than connectional specificity, attractor dynamics, Hebbian learning, and sigmoidal nonlinearities, but it behaves in a sophisticated way and is consistent with most of the observed properties of real head direction cells. In addition it makes a number of predictions that ought to be testable by reasonably straightforward experiments.
