Накратко на български

Невронните механизми, чрез които мозъкът разпознава групи от свързани обекти, като например вилица и нож около чиния, са в центъра на анализа. Това помага да се разбере как се обработва информацията между виждането на единичен предмет и цяла сцена.

Exploring the continuum between objects and scenes: The neural basis of object-constellation processing

Where much is known about the partially distinct neural bases of single-object and whole-scene processing, neural investigations of stimuli along the continuum between these two anchorpoints have been rare. Yet there is a conflict here with our daily experiences, where we rarely encounter objects in complete isolation (e.g., a lone fork). Instead, we regularly find objects as part of a group whose multiple components bear conceptual relevance to each other (e.g., a fork and knife either side of a plate). Despite the importance of such ‘object constellations’ for human behaviour, we presently know remarkably little about the neural representation of them in the brain. The goal of the project is to address this substantial in our understanding of the intermediate representational space between objects and scenes. By bringing advanced neurocognitive methods to bear on the question of how the brain processes object constellations (OCs), I aim to provide the first systematic investigation of how the brain represents familiar / meaningful configurations of objects. Results will shed new light on the statistical regularities the brain is specialised to exploit, and advance our understanding of the intermediary representational space between single-objects and whole-scenes. The project’s twin objectives are centred on revealing the neural representations of object constellations in both space and time.

Цел на проекта

Human visual recognition is remarkably efficient. With just a single glance, we can identify our surroundings as a forest, a street, or an office, or determine whether a specific object contained in the scene is a deer, a car, or a computer. Uncovering the neural mechanisms underlying such fast and accurate recognition has been a core initiative in cognitive neuroscience, such that the structural and functional characteristics of object-selective and scene-selective cortex are now well understood. Yet there is a surprising and substantial gap in our understanding of the intermediate representational space between objects and scenes: One relevant level of visual organisation that has received very little attention to date is the 'object-constellation', defined here as a familiar configuration of objects bearing conceptual relevance to each other (e.g., a fork and knife arranged either side of a plate). Just as the visual system exploits physical regularities in Gestalt-like grouping, we hypothesise that the learned statistical regularities contained in object-constellations give rise to a higher-order perceptual unit, the neural basis of which has yet to be explored. This project will bring advanced neurocognitive methods to bear on the question of how the brain processes familiar object-constellations, using fMRI and MEG to characterise the spatiotemporal profile of object-constellation representation in the human brain. In providing the first systematic investigation of the neural representation of object-constellations, this work will shed new light on the statistical regularities the brain is specialised to exploit, and advance our understanding of the intermediary representational space between single-objects and whole-scenes.
