According to the "labeled line" theory in sensory processing,different neurons in the primary visual cortex（V1） register different local stimulus features;on the other hand,V1 neuronal responses can be affected by global stimulus *** influences in V1 have been interpreted to play diverse roles in mediating various center-surround interactions,but it is unclear whether the V1 signals conveying figural information defined by different stimulus contexts share similar *** examining the response properties of V1 neurons in monkeys detecting different forms of targets within complex backgrounds,we found that V1 plays a double role in stimulus labeling:registering the local stimulus attributes and marking the local elements within the global context as belonging either to the figure or to the *** latter global labehng,which is superimposed on but can be dissociated from the local labeling,is independent of neuronal feature selectivities and of the global figural attributes when the sahency of the figure is *** instance,when the figure to be detected was a global contour made of collinear lines embedded in randomly oriented tines,we could dissociate a general additive response component that was dependent on the global saliency of the contour but was independent of neuronal orientation selectivity and of the global contour ***,this additive effect was indistinguishable when the neuron’s receptive field was centered on any local element lying on the contour path,even if the element in the receptive field was in marked feature contrast with the other stimulus ***,the response component associated with the global labehng gradually faded when the luminance contrast between the background and the figure was increased,indicating dependence of the global labeling process on the complex *** other forms of stimuli with global figure-ground configurations showed similar results,suggesting a general mec
