#eNeuro | Scene Perception–Memory Pairing Extends to the Superior Parietal Cortex https://doi.org/10.1523/ENEURO.0155-26.2026

doi.orgScene Perception–Memory Pairing Extends to the Superior Parietal CortexVisual scene analysis relies on a set of scene-selective regions in the posterior cerebral cortex (OPA, PPA, MPA), with a paired memory-responsive counterpart located in the anterior (LPMA, VPMA) or overlapping (MPMA) cortex. The interaction between these pairs of regions is thought to integrate visual input with mnemonic context. Recently, a fourth scene perception area in the superior parietal cortex (the superior place area, SPA) was identified, with a proposed role in visually guided navigation. Whether this region also has an anterior paired memory region is currently unknown. Across two independent fMRI datasets (total N  = 24, 14 females) using static or dynamic stimuli and distinct memory tasks, we show that recalling visual scenes evokes robust responses in a region immediately anterior and dorsal to SPA (referred to here as the superior place memory area, SPMA). During resting-state fMRI, SPA preferentially coupled with the other scene perception areas, while SPMA preferentially coupled with the other place memory areas. At the whole-brain level, seed-based connectivity revealed that SPA sits at the confluence of four processing streams spanning regions implicated in egocentric scene perception, map-based navigation, perspective taking, and goal-directed movement. These findings extend the perception–memory motif associated with visual scene processing to a fourth cortical surface. The widespread anatomical coupling between scene perception and memory processes reflects the importance of this interaction for flexible, context-grounded navigation.

Nottingham staff will strike on 30 September and 1 October as University Council meets to decide the future of jobs and courses. Further strike action will run from 5 October to 11 December. Management can still stop this: rule out compulsory redundancies and protect teaching and research.

👁️🧠🧪 Vision takes time. But how does visual information flow through the human brain? Our new PLOS Computational Biology paper uses population receptive field (pRF) modelling to bring the spatial precision of fMRI to MEG, revealing the temporal dynamics of visual areas. 📖 doi.org/10.1371/jour...

Taken together, our results suggest the visual brain encodes information in a statistically efficient way that reflects the co-occurrence of features within natural variation of real world objects.

Component scores indicate many object features are represented on each component (seen here for MEG again). Each component embodies multiple features, suggesting the brain is tuned to statistical co-occurrences of features amongst natural variation in real world objects.

Importantly, we find good correspondence of the components between the MEG, EEG, and fMRI datasets. This indicates the PLSR identified robust neural representations which are at least partially shared over subjects, imaging modalities, and experimental paradigms.

Similarly, the component loadings show smooth oscillations post ~100ms, along with smooth spatial topographies over sensors, as they track the evoked response over time (seen here for an example MEG subject)

This is a follow-up to our previous Journal of Neuroscience paper. There we applied a data-driven analysis to fMRI data to uncover organising gradients of the visual brain. Here, we adapt our approach for time-resolved analyses of EEG & MEG data.

Finally, today is the day: Josefine Zerbe will present and release our new multi-echo 7T fMRI dataset LAION-fMRI during #VSS2026, with >30 fMRI session per subject and unprecedented stimulus diversity. Come to Talk Room 1 (Scene perception) today at 5:15. Details will follow in a separate thread!

We also compare connectivity fingerprints for individual regions in the face & scene networks. Fingerprints are similar but still distinct between regions in each network, indicating connectivity profiles track differences in functional specialisations between regions.

We measure whole-brain functional connectivity "fingerprints" of face & scene regions, representing patterns of connectivity with the rest of the brain, in multiple movie-watching and resting-state datasets. We compare these fingerprints across 2 independent splits of each dataset.

Connectivity fingerprints are highly similar across people, but also more similar within a person than between people, showing connectivity profiles of face & scene regions track individual differences.

Excited to share a new article from @icevislab.bsky.social! In a sample of over 60 people, we found distinct neural differences underlying object and face recognition in dyslexia. These findings highlight crucial domain-general visual processes that may contribute to word reading challenges.
