以前的研究已经确定了一个人口的细胞记录在后下托和丘脑前核（ATN），放电作为一个功能的动物的头部方向（HD）在水平面上。本实验监测HD细胞的活动时，大鼠面临的情况下，从内部感觉来源（如本体感受，前庭，或运动传出复制）的方向信息与来自熟悉的，外部地标的方向信息相冲突。结果表明，当一个显着的，熟悉的线索被重新引入到大鼠的环境到一个位置，与细胞的电流发射方向相冲突，HD细胞在ATN和后下托改变他们的首选方向，以反映他们最初建立的方向与此线索。这一发现表明，从外部地标线索到HD细胞的感觉输入能够覆盖通过内部感觉线索开发的空间信息。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
Previous studies have identified a population of cells recorded in the postsubiculum and the anterior thalamic nucleus (ATN) that discharge as a function of an animal's head direction (HD) in the horizontal plane. The present experiments monitored HD cell activity when rats were confronted with a situation in which directional information from internal sensory sources (eg, proprioceptive, vestibular, or motor efference copy) conflicted with directional information derived from familiar, external landmarks. Results showed that when a salient, familiar cue was reintroduced to rat's environment into a position that conflicted with the cell's current firing direction, HD cells in both the ATN and the postsubiculum shifted their preferred direction to reflect their originally established orientation with this cue. This finding suggests that sensory inputs onto HD cells from external landmark cues are capable of overriding spatial information developed through internal sensory cues.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
