移情是社会交往的重要组成部分,涉及体验他人的感官和情感状态。我们观察到,与经历疼痛或吗啡镇痛的小鼠进行短暂的社会互动,导致这些经验转移到其社会伙伴。光遗传学的操作表明,前扣带皮层(ACC)和它的投射到丘脑核(NAc)选择性地参与疼痛和镇痛的社会转移。相比之下,ACC→NAc回路对于恐惧的社会传递并不是必需的,而是依赖于ACC对基底外侧杏仁核的投射。这些发现表明,ACC是一个与人类共情反应密切相关的大脑区域,通过影响不同的下游靶点来介导小鼠不同形式的共情。小鼠表现出不同的移情样行为,这取决于前扣带皮层的不同下游目标的投影。
Empathy is an essential component of social communication that involves experiencing others sensory and emotional states. We observed that a brief social interaction with a mouse experiencing pain or morphine analgesia resulted in the transfer of these experiences to its social partner. Optogenetic manipulations demonstrated that the anterior cingulate cortex (ACC) and its projections to the nucleus accumbens (NAc) were selectively involved in the social transfer of both pain and analgesia. In contrast, the ACC→NAc circuit was not necessary for the social transfer of fear, which instead depended on ACC projections to the basolateral amygdala. These findings reveal that the ACC, a brain area strongly implicated in human empathic responses, mediates distinct forms of empathy in mice by influencing different downstream targets. Mice exhibit different empathy-like behaviors that are dependent on anterior cingulate cortex projections to distinct downstream targets.
