1. Introduction Spatial cognition concerns the ability to acquire, organize, store and retrieve knowledge of spatial properties (e.g., location, distance, direction) in the complex environment in order to navigate and perceive location precisely (Allen et al., 1996; Hardiess et al., 1999). It is one of the most important abilities that animals and humans have to help them adapt and survive in the world. For example, identifying food location, wayfinding, perceiving scenes are all based on this ability. For many years, elegant behavioral, neurobiological and neuropsychological methods have been used to investigate the spatial behavior of human and non-human species (Denis & Loomis, 2007). In this essay, I am going to talk about how different neuroscientific approaches contribute to our understanding of neural bases of spatial cognition and their role in related processes. 2. Brain regions involved in spatial cognition and related processes Much studies using various methods, including single-unit recordings, patient/lesion studies, non-invasive brain imaging and brain interference studies, have been done to investigate neural mechanisms underlying spatial cognition. As results, researchers have found several brain regions involved in processing of spatial information, including parietal cortex and hippocampus (Burgess, Jeffery, & O'Keefe, 1999). Also, it is very important to know which reference frame is used when we discussing spatial functions of these brain regions
