title: Automatic spread of attentional response modulation along Gestalt criteria in primary visual cortex.
abstract: Visual attention can select spatial locations, features and objects. Theories of object-based attention claim that attention enhances the representation of all parts of an object, even parts that are not task relevant. We recorded neuronal activity in area V1 of macaque monkeys and observed an automatic spread of attention to image elements outside of the attentional focus when they were bound to an attended stimulus by Gestalt criteria.
