Activity in the monkey hippocampal formation (HF) was analyzed during movement guided by auditory and visual cues. The monkey could control a motorized cab by pressing the proper 1 of 4 available levers within a 2.5 x 2.5 m field. Of 238 HF neurons analyzed, responses of 79 were place related and responses of 110 were task related. Of the task-related neurons, 33 were also place related, and responded to task cues only where place-related responses occurred. The results suggest HF gating of incoming non-spatial information, depending on information about location.
在由听觉和视觉线索引导的运动过程中，对猴子海马结构（HF）的活动进行了分析。猴子可以通过在2.5×2.5米的区域内按下4个可用杠杆中的适当一个来控制电动驾驶室。在分析的238个HF神经元中，79个的反应与位置相关，110个的反应与任务相关。在与任务相关的神经元中，33个也与位置相关，并且仅在发生与位置相关反应的地方对任务线索做出反应。结果表明，HF对传入的非空间信息进行门控，这取决于有关位置的信息。
