Classification methods show that the spatial pattern of a functional magnetic resonance imaging response across the cortex contains category information, but whether such patterns are used, or 'read out', in behavioral performance remains untested. We show that although the spatial pattern in both the retinotopic and lateral occipital cortex (LOC) in humans contains category information, only in the LOC is the pattern stronger for correct than for incorrect trials. Thus, some, but not all, spatial patterns are read out during task performance.
分类方法表明，功能性磁共振成像在整个皮层的响应空间模式包含类别信息，但这种模式是否在行为表现中被使用或“读出”仍未得到验证。我们发现，尽管人类视网膜拓扑和枕叶外侧皮质（LOC）中的空间模式都包含类别信息，但只有在LOC中，正确试验的模式比错误试验的模式更强。因此，在任务执行过程中，一些但不是所有的空间模式会被读出。
