Subordinate Categorization Enhances the Neural Selectivity in Human Object-selective Cortex for Fine Shape Differences
There is substantial evidence that object representations in adults are dynamically updated by learning. However, it is not clear to what extent these effects are induced by active processing of visual objects in a particular task context on top of the effects of mere exposure to the same objects. Here we show that the task does matter. We performed an event-related fMRI adaptation study in whi...
متن کاملThe representation of subordinate shape similarity in human occipitotemporal cortex.
We investigated the coding of subordinate shape similarity in human object-selective cortex in two event-related functional magnetic resonance adaptation (fMR-A) experiments. Previous studies using faces have concluded that there is a narrow tuning of neuronal populations selective to each face, and that tuning is relative to the expected "average" face (norm-based encoding). Here we investigat...
متن کاملVisual task enhances spatial selectivity in the human auditory cortex
The auditory cortex represents spatial locations differently from other sensory modalities. While visual and tactile cortices utilize topographical space maps, for audition no such cortical map has been found. Instead, auditory cortical neurons have wide spatial receptive fields and together they form a population rate code of sound source location. Recent studies have shown that this code is m...
متن کاملCategorization Training Results in Shape- and Category-Selective Human Neural Plasticity
Object category learning is a fundamental ability, requiring the combination of "bottom-up" stimulus-driven with "top-down" task-specific information. It therefore may be a fruitful domain for study of the general neural mechanisms underlying cortical plasticity. A simple model predicts that category learning involves the formation of a task-independent shape-selective representation that provi...
متن کاملSubordinate-level Object Recognition 1 Running Head: Face and Object Recognition Does Visual Subordinate-level Categorization Engage the Functionally-deened Fusiform Face Area? Subordinate-level Object Recognition 2
Functional magnetic resonance imaging was used to compare brain activation associated with basic-level (e.g., BIRD) and subordinate-level (e.g., EAGLE) processing for both visual and semantic judgments. We localized the putative face area for eleven subjects, who also performed visual matching judgments for pictures and aurally-presented words. The middle fusiform and occipital gyri were recrui...
