关于海马体系统功能的理论主要基于两个基本发现:在著名的病人H.M.以及海马神经元放电活动与大鼠空间位置有关的观察。在这些发现的脚步声中,人们做了许多尝试来调和这些看似不同的功能。在这里,我们提出,记忆和规划的机制已经从物理世界中的导航机制演变而来,并假设在真实的和心理空间中导航的神经元算法基本上是相同的。我们回顾支持这一假设的实验数据,并讨论如何特定的放电模式和振荡动力学内嗅皮层和海马可以支持导航和记忆。
Theories on the functions of the hippocampal system are based largely on two fundamental discoveries: the amnestic consequences of removing the hippocampus and associated structures in the famous patient H.M. and the observation that spiking activity of hippocampal neurons is associated with the spatial position of the rat. In the footsteps of these discoveries, many attempts were made to reconcile these seemingly disparate functions. Here we propose that mechanisms of memory and planning have evolved from mechanisms of navigation in the physical world and hypothesize that the neuronal algorithms underlying navigation in real and mental space are fundamentally the same. We review experimental data in support of this hypothesis and discuss how specific firing patterns and oscillatory dynamics in the entorhinal cortex and hippocampus can support both navigation and memory.
