听觉注意对感知和听觉皮层的声音处理过程具有重要影响，但对皮层下听觉通路中注意调节的程度仍知之甚少。我们使用功能性磁共振成像的下丘和听觉皮层在一个苛刻的通道间选择性注意任务，使用沉默的成像范式，旨在优化下丘激活的影响，检查通道间的注意。下丘和听皮层对声音都有较强的激活，但注意调节仅限于听皮层。
Auditory attention powerfully influences perception and modulates sound processing in auditory cortex, but the extent of attentional modulation in the subcortical auditory pathway remains poorly understood. We examined the effects of intermodal attention using functional magnetic resonance imaging of the inferior colliculus and auditory cortex in a demanding intermodal selective attention task using a silent imaging paradigm designed to optimize inferior colliculus activations. Both the inferior colliculus and auditory cortex showed strong activations to sound, but attentional modulations were restricted to auditory cortex.
