Using functional magnetic resonance imaging, ten healthy subjects were scanned whilst listening to consonant-vowel syllables under three different conditions: (i) a 'no-attention' condition required subjects to ignore the stimuli; (ii) an 'attend' condition requiring attentive listening to stimuli; (iii) a 'detect' condition requiring detection of a specific target syllable. Hemodynamic responses were measured in the primary and secondary auditory cortex. These three conditions were associated with significantly different activations in the primary and secondary auditory cortex. The strongest activations were found for the 'detect' condition, followed by the 'attend' condition. The weakest activation was evident during the 'no-attention' condition. There were also stronger activations in the left hemisphere and within the primary auditory cortex. These results suggest that the primary and secondary auditory cortex play a main role in the selective attention.
使用功能磁共振成像技术，对10名健康受试者在三种不同条件下听辅音-元音音节时进行扫描：（i）“不注意”条件要求受试者忽略刺激；（ii）“注意”条件要求专注地听刺激；（iii）“检测”条件要求检测特定目标音节。在初级和次级听觉皮层测量血流动力学反应。这三种条件与初级和次级听觉皮层中显著不同的激活相关。“检测”条件下的激活最强，其次是“注意”条件。在“不注意”条件下激活最弱。左半球和初级听觉皮层内也有更强的激活。这些结果表明，初级和次级听觉皮层在选择性注意中起主要作用。
