title: Processing of visual and non-visual naturalistic spatial information in the
|
|
"parahippocampal place area"
|
|
description: "The \u201Cparahippocampal place area\u201D (PPA) in the human ventral\
|
|
\ visual stream exhibits increased hemodynamic activity correlated with the perception\
|
|
\ of landscape photos compared to faces or objects. Here, we investigate the perception\
|
|
\ of scene-related, spatial information embedded in two naturalistic stimuli. The\
|
|
\ same 14 participants were watching a Hollywood movie and listening to its audio-description\
|
|
\ as part of the open-data resource studyforrest.org. We model hemodynamic activity\
|
|
\ based on annotations of selected stimulus features, and compare results to a block-design\
|
|
\ visual localizer. On a group level, increased activation correlating with visual\
|
|
\ spatial information occurring in the movie is overlapping with a traditionally\
|
|
\ localized PPA. Activation correlating with semantic spatial information occurring\
|
|
\ in the audio-description is more restricted to the anterior PPA. On an individual\
|
|
\ level, we find significant bilateral activity in the PPA of nine individuals and\
|
|
\ unilateral activity in one individual. Results suggest that activation in the\
|
|
\ PPA generalizes to spatial information embedded in a movie and an auditory narrative,\
|
|
\ and may call for considering a functional subdivision of the PPA."
