摘要：

In V1, neurons preferring similar orientations are grouped in columns too small to be resolved by conventional fMRI. Two studies circumvent this limitation by using algorithms to recognize patterns of activation across a large area. This new trick allows the authors to distinguish responses to different orientations in human V1 and to study its contribution to conscious perception.
