Spatial navigation is a crucial ability involving the interplay of multiple cognitive processes and is related to input spatial information (such as landmarks and orientation cues) and output navigational strategies (such as route-based and map-based). It is still not clear where is the spatial navigation system and whether these tasks evoke different activation patterns in human brain. Thus, we analyzed the reported brain activations of 33 related functional neuroimaging studies by using activation likelihood estimation (ALE) meta-analyses. Statistical analysis revealed a navigational system including the hippocampus, parahippocampal place area (PPA), retrosplenial complex (RSC), occipital place area (OPA), and insula. More likely, landmarks activate the left secondary motor cortex (SMC), whereas orientation cues activate the right somatosensory associative cortex (SAC). Although no region showed stronger activation likelihood in route- than map-based navigation, the map-based navigation had stronger activation likelihood in the right SAC than route-based navigation. These findings revealed the brain representation of spatial navigational system and suggested that different parts of this system are involved with the specific navigational tasks.
空间导航是一种涉及多种认知过程相互作用的关键能力,与输入的空间信息(如地标和方向线索)和输出的导航策略(如基于路线和基于地图的导航)有关。目前还不清楚空间导航系统在哪里,以及这些任务是否会在人类大脑中引起不同的激活模式。因此,我们通过激活似然估计(ALE)荟萃分析,对 33 项相关功能神经影像学研究的报告脑激活进行了分析。统计分析显示了一个包含海马体、副海马体位置区域(PPA)、后扣带回复合体(RSC)、枕部位置区域(OPA)和岛叶的导航系统。更有可能的是,地标激活左侧次级运动皮层(SMC),而方向线索激活右侧躯体感觉联合皮层(SAC)。尽管在基于路线和基于地图的导航中没有区域显示出更强的激活可能性,但基于地图的导航在右侧 SAC 中的激活可能性强于基于路线的导航。这些发现揭示了空间导航系统的大脑表征,并表明该系统的不同部分参与了特定的导航任务。
