We also compare the group-based probabilistic location of the place memory areas with resting state networks, functional atlases, and large-scale gradients.

These results establish the PMAs at inflection points along the cortical hierarchy between unimodal sensory and transmodal, apical regions.

In this larger cohort of participants, we replicate our original work, wherein we show that place memory activity is located anterior to scene perception.

We combine three datasets (N=44 participants) to demonstrate the reliability of the place memory areas' location.

Results did not depend on the localizer conditions used.

Contrasting memory of scene vs faces, or scenes vs. familiar faces, bodies, objects, and famous faces yielded the same areas.

Have you wondered where scene perception and memory intersect in the brain?

Do you want to localize these areas?

In a preprint, @carolinerobertson.bsky.social, Deepa Prasad, Brenda Garcia, and I detail this topography and release these parcels and our localizer.

This visuospatial coding scheme (retinotopy) is widespread in the brain.

So, retinotopy might be a “common currency”, allowing information to be translated seamlessly between neural systems.

This opponent coding scheme flips during recall: memory areas are active, and perceptual areas are deactivated in a retinotopically-specific manner.

Turns out, mnemonic brain areas implement the same neural coding principle as the visual system (retinotopy). 

Surprisingly, their retinotopic code is inverted: visual stimulation leads to spatially-specific deactivations. (see work from Thomas Knapen and @chrisklink.bsky.social )
