The superior colliculus (SC) plays a crucial role in spatial attention. Additionally, the occipital place area (OPA) in the dorsal occipitoparietal cortex is involved in perceiving the affordance structure of navigable space. Research on spatial navigation indicates that intersections play a pivotal role in the early development of spatial representations, supporting the parallel hypothesis of combining self-motion and landmark cues. Spatial navigation is a multi-componential function crucial for navigating complex environments, with older individuals more likely to use egocentric strategies. The OPA is identified as the perceptual source of boundary information crucial for spatial navigation, as disruptions in the right OPA impair spatial memory for boundary-tethered objects.
