We used functional magnetic resonance imaging (fMRI) to assess cortical involvement in a hidden pattern task. The experimental and control conditions involved judgment of the presence/absence versus the position of a complex pattern. Activation specific to hidden pattern identification was concentrated on frontal, dorsal parietal, and mesolimbic cortex. This was consistent not only across individual subjects, but with hidden figures tasks used in previous fMRI investigations. Results suggest that pattern identification relies on a relatively stable neural network controlling selective attention. In combination with fMRI, hidden pattern tasks may be useful in neuropsychological assessment of visual search and object identification.
我们使用功能磁共振成像（fMRI）来评估隐藏模式任务中的皮质参与情况。实验和对照条件涉及对复杂模式的存在/缺失与位置的判断。特定于隐藏模式识别的激活集中在前额、背侧顶叶和中脑边缘皮质。这不仅在个体受试者中一致，而且与以前 fMRI 研究中使用的隐藏图形任务一致。结果表明，模式识别依赖于控制选择性注意的相对稳定的神经网络。与 fMRI 相结合，隐藏模式任务可能有助于视觉搜索和物体识别的神经心理学评估。
