The Neural Basis for Spatial Relations
Studies in semantics traditionally focus on knowledge of objects. By contrast, less is known about how objects relate to each other. In an fMRI study, we tested the hypothesis that the neural processing of categorical spatial relations between objects is distinct from the processing of the identity of objects. Attending to the categorical spatial relations compared with attending to the identit...
متن کاملThe neural basis of anosognosia for spatial neglect after stroke.
BACKGROUND AND PURPOSE The present study investigated the lesion anatomy of anosognosia for visuospatial neglect resulting from right hemispheric stroke. METHODS In 63 patients, self-ratings of performance in paper-and-pencil tests were contrasted with external performance ratings. Lesion analysis was conducted on patient subgroups with different degrees of anosognosia but comparable visuospa...
متن کاملA neural circuit basis for spatial working memory.
The maintenance of a mental image in memory over a time scale of seconds is mediated by the persistent discharges of neurons in a distributed brain network. The representation of the spatial location of a remembered visual stimulus has been studied most extensively and provides the best-understood model of how mnemonic information is encoded in the brain. Neural correlates of spatial working me...
متن کاملLearning to Compose Spatial Relations with Grounded Neural Language Models
Language is compositional: we can generate and interpret novel sentences by having a notion of meaning of their individual parts. Spatial descriptions are grounded in perceptional representations but their meaning is also defined by what neighbouring words they co-occur with. In this paper we examine how language models conditioned on perceptual features can capture the semantics of composed ph...
متن کاملImplementing Spatial Relations in Neural Nets: Figure/Ground and Containment
There is, no doubt, a division among mental functions. Some are learned, while some are innate. I argue that lower functions, that is, those that are perceptual primitives and are required for much higher level processing, are more likely to be innate than are higher functions, which are more likely to be learned (and therefore culturally a ected). In the eld of object recognition, it is likely...
