“…We did not find any evidence for age-related modulations of lower frequencies in the PPA. The PPA processes scene content and layout as the natural statistics of a scene explain a large proportion of its variance (Bonner and Epstein, 2021; Chaisilprungraung and Park, 2021; Dwivedi, Cichy and Roig, 2021; Aminoff and Durham, 2023). The comparable delta/theta synchronization in the PPA across age groups lends credence to the idea that older adults can adequately extract visual information that is devoid of navigational purpose.…”

Position is a key property that allows certain objects in the environment to attain navigational relevance. Symmetrical processing of object position across the horizontal meridian remains an unchallenged assumption of the spatial navigation literature. Nonetheless, a growing body of research reports vertical inhomogeneities in perceptual tasks, and recent evidence points towards a lower visual field preference in healthy aging. Factoring in the vertical position of objects to better apprehend spatial navigation abilities across the lifespan is essential. The occipital place area (OPA), parahippocampal place area (PPA), and medial place area (MPA) are ideal candidates to support the processing of the vertical location of navigational cues. Indeed, they are implicated in scene processing and spatial cognition, functions that may interact with their underlying retinotopic codes. This study aimed to elucidate whether young and older participants adjusted their gaze patterns and EEG activity within scene-selective regions in response to the vertical arrangement of landmarks. A sample of 21 young and 21 older participants completed a desktop-based task requiring them to navigate using objects at different vertical locations. We equipped them with an eye tracker and a high-density EEG cap. We used a fMRI-informed source-reconstruction algorithm to study the OPA, PPA and MPA with high spatial and temporal precision. Older adults exhibited a higher number of errors compared to young adults during reorientation. This age-related decline in accuracy was accompanied by a tendency among older participants to fixate objects in the lower half of the screen. This gaze bias was absent in young participants, who instead adapted their oculomotor behaviour based on the position of navigationally-relevant information. Another primary finding pertains to the differential pattern of theta and beta band activity in the OPA, PPA and RSC for environments that only contained relevant cues in the upper visual field. It thus appears that scene-selective regions process some aspect of the vertical position of information, irrespectively of their inherent retinotopic biases. Moreover, we revealed striking disparities between age groups in beta/gamma band synchronization in all scene-selective regions, indicating compromised top-down attentional mechanisms during spatial navigation in ageing. These age-related disparities in attentional dynamics might account for performance deficits in older participants. This study sheds light on a systematic downward gaze bias and altered attentional dynamics within scene-selective regions during spatial navigation in older age. It also emphasises the importance of considering vertical positioning as a fundamental property of objects within scenes.

“…The role of the PPA in perceiving architectural spaces was further studied in two human fMRI experiments, where it was demonstrated that the PPA and the OPA processed the borders of scenes based on the observer's space rather than the physical environment. The PPA activation was also shown to be more sensitive to changes related to mid-level perceptual characteristics of scenes (such as the rectilinear pattern of window frames) [23]. Furthermore, the PPA seems to be view-point specific [24] and primarily focuses on the perception of an immediate scene [25].…”

The study of neuroarchitecture is concerned with the significant effects of architecture on human behavior, emotions and thought processes. This review explores the intricate relationship between the brain and perceived environments, focusing on the roles of the anterior cingulate cortex (ACC) and parahippocampal place area (PPA) in processing architectural stimuli. It highlights the importance of mirror neurons in generating empathetic responses to our surroundings and discusses how architectural elements like lighting, color, and space layout significantly impact emotional and cognitive experiences. The review also presents insights into the concept of cognitive maps and spatial navigation, emphasizing the role of architecture in facilitating wayfinding and orientation. Additionally, it addresses how neuroarchitecture can be applied to enhance learning and healing environments, drawing upon principles from the Reggio Emilia approach and considerations for designing spaces for the elderly and those with cognitive impairments. Overall, this review offers a neuroscientific basis for understanding how human cognition, emotions, spatial navigation, and well-being are influenced by architectural design.

“…These studies demonstrate that object structures within a scene readily affect scene memory. Another fMRI study suggests that not only the spatial relations between objects within a scene affect memory, but also the task-irrelevant immediate surroundings where the observers view the scene (Chaisilprungraung & Park, 2021). The OPA processes whether a scene is viewed from outside or inside a room through windows.…”

Humans have been exposed to a continuous stream of scenes since the first day of life. Through constant processing and encoding of scenes, the human brain develops scene knowledge that aids current scene understanding and guides future scene memory and decision-making. In this chapter, we will discuss how humans’ scene memories and understandings are shaped by (1) scene-level properties that are intrinsic to a scene or that arise through comparisons, (2) observer-level properties, such as prior knowledge, cognitive states, and ages, and (3) new knowledge generated through the interactions between scene- and observer level information.
