对其他处于困境中的人的社会敏感性对于生存至关重要。前扣带皮层 (ACC) 是一种参与行为选择的结构,并受到观察到的疼痛或痛苦的影响。然而,我们对这种敏感性背后的神经回路的理解并不完整。在这里,我们揭示了当亲代小鼠通过将陷入困境的幼崽送回巢穴(“幼崽回收”)来做出反应时,ACC 的意外性别依赖性激活。我们观察到父母照顾期间兴奋性和抑制性 ACC 神经元之间相互作用的性别差异,并且 ACC 兴奋性神经元失活增加了幼崽的忽视。蓝斑 (LC) 在幼崽回收过程中在 ACC 中释放去甲肾上腺素,LC-ACC 通路的失活会扰乱父母的照顾。我们得出的结论是,ACC 在 LC 调制下保持对幼犬痛苦的性别依赖性敏感性。我们认为 ACC 参与养育子女提供了一个机会来识别支持对他人情绪困扰敏感的神经回路。科罗娜等人。确定从蓝斑到扣带皮层的去甲肾上腺素能通路,这对父母的照顾很重要。利用全脑活动图谱、纤维光度测定和化学遗传学失活,他们表明该通路中的性别依赖性活动对于母性行为很重要,并且去甲肾上腺素调节 ACC 对幼崽应激的反应。
Social sensitivity to other individuals in distress is crucial for survival. The anterior cingulate cortex (ACC) is a structure involved in making behavioral choices and is influenced by observed pain or distress. Nevertheless, our understanding of the neural circuitry underlying this sensitivity is incomplete. Here, we reveal unexpected sex-dependent activation of ACC when parental mice respond to distressed pups by returning them to the nest (“pup retrieval”). We observe sex differences in the interactions between excitatory and inhibitory ACC neurons during parental care, and inactivation of ACC excitatory neurons increased pup neglect. Locus coeruleus (LC) releases noradrenaline in ACC during pup retrieval, and inactivation of the LC-ACC pathway disrupts parental care. We conclude that ACC maintains sex-dependent sensitivity to pup distress under LC modulation. We propose that ACC’s involvement in parenting presents an opportunity to identify neural circuits that support sensitivity to the emotional distress of others. Corona et al. identify a noradrenergic pathway from locus coeruleus to cingulate cortex important for parental care. Using brain-wide activity mapping, fiber photometry, and chemogenetic inactivation, they show that sex-dependent activity in this pathway is important for maternal behavior and that noradrenaline modulates ACC’s response to pup distress.
