Abstract
The neural systems supporting scene-perception and spatial-memory systems of the human brain are well-described. But how do these neural systems interact? Here, using fine-grained individual-subject fMRI, we report three cortical areas of the human brain, each lying immediately anterior to a region of the scene perception network in posterior cerebral cortex, that selectively activate when recalling familiar real-world locations. Despite their close proximity to the scene-perception areas, network analyses show that these regions constitute a distinct functional network that interfaces with spatial memory systems during naturalistic scene understanding. These "place-memory areas" offer a new framework for understanding how the brain implements memory-guided visual behaviors, including navigation.

Mapping the organization and dynamics of the posterior medial network during movie watching

TL;DR: In this paper, the authors investigated the functional connectivity of the posterior medial network (PMN) during movie watching to identify its pattern of connections and subnetwork functions in a split-sample replication of 136 participants.

The human brain uses spatial schemas to represent segmented environments

TL;DR: In this article, a virtual courtyard was divided into two halves by a river, and the spatial locations were encoded within this environment using spatial schemas and integrated spatial maps, and participants' spatial judgments and multivoxel activation patterns were affected by the division of the courtyard.

Perception and memory have distinct spatial tuning properties in human visual cortex

TL;DR: In this paper , the authors leverage population receptive field models to parameterize fMRI activity in human visual cortex during spatial memory retrieval, and demonstrate that this property is well explained by the hierarchical structure of the visual system.

Three cortical scene systems and their development

TL;DR: In this article , the authors proposed that cortical scene processing regions support three distinct computational goals (and one not for navigation at all): (i) the parahippocampal place area supports scene categorization, which involves recognizing the kind of place we are in; (ii) the occipital place area supported visually guided navigation, which involved finding our way through the immediately visible environment, avoiding boundaries and obstacles; and (iii) the retrosplenial complex supported map-based navigation, and (iv) the this article proposed that these systems develop along different timelines, with both navigation systems developing slower than the scene categorisation system.
