	pairs of neurons with overlapping or collinear receptive fields.
	By sampling more broadly and employing stimuli that contain partially
	occluded objects, we have conducted a more incisive test of the binding
	by synchrony hypothesis in area MT. We find that synchrony in spiking
	activity shows little dependence on feature grouping, whereas gamma
	band synchrony in field potentials can be significantly stronger
	when features are grouped. However, these changes in gamma band synchrony
	are small relative to the variability of synchrony across recording
	sites and do not provide a robust population signal for feature grouping.
	Moreover, these effects are reduced when stimulus differences nearby
	the receptive fields are eliminated using partial occlusion. Our
	findings suggest that synchrony does not constitute a general mechanism
	of visual feature binding.},
