暗示奖励、威胁或危险的线索的重要性表明，它们在感知和注意力的神经系统中获得了处理特权。先前的研究已经证明了动机显著线索的增强处理，并指出杏仁核是增强的潜在神经结构。在目前的研究中，我们检查了杏仁核是否是这种注意力的情绪调节所必需的。单侧杏仁核病变的患者和匹配的对照组完成了情绪注意力瞬脱任务，其中情绪干扰物损害了对后续目标的感知。在所有参与者中，情绪化的图像都被证明更容易分散注意力，包括那些右侧或左侧杏仁核损伤的人。这些数据反对杏仁核在调节情绪刺激引起的所有类型的注意力捕获中的核心作用。
The importance of cues signaling reward, threat or danger would suggest that they receive processing privileges in the neural systems underlying perception and attention. Previous research has documented enhanced processing of motivationally salient cues, and has pointed to the amygdala as a candidate neural structure underlying the enhancements. In the current study, we examined whether the amygdala was necessary for this emotional modulation of attention to occur. Patients with unilateral amygdala lesions and matched controls completed an emotional attentional blink task in which emotional distractors impair the perception of subsequent targets. Emotional images proved more distracting across all participant groups, including those with right or left amygdala lesions. These data argue against a central role for the amygdala in mediating all types of attentional capture by emotional stimuli.
