母婴关系在分娩后迅速发展,并伴随着感官知觉和行为的变化。在这里,我们研究了超声波发声 (USV) 在母亲大脑中的表现。使用允许对活跃神经元进行时间控制遗传访问的小鼠品系,我们发现母亲的颞关联皮层 (TeA) 表现出强大的 USV 反应。对 USV 反应神经元的狂犬病追踪揭示了 TeA 的大量皮质下和皮质输入。一个特别重要的皮层输入源是初级听觉皮层 (A1),这表明 A1 与 TeA 之间有很强的连接性。在幼崽检索试验中,TeA 中 USV 响应神经元的化学遗传学沉默会损害听觉驱动的母体偏好。此外,清醒小鼠的密集细胞外记录揭示了TeA中单个神经元和群体对USV反应的变化;与幼崽相比,提高了母亲对幼崽叫声的辨别能力。这些数据表明,TeA 在编码和感知母性期间幼犬哭声方面发挥着关键作用。
Mother-infant bonding develops rapidly following parturition and is accompanied by changes in sensory perception and behavior. Here, we studied how ultrasonic vocalizations (USVs) are represented in the brain of mothers. Using a mouse line that allows temporally controlled genetic access to active neurons, we found that the temporal association cortex (TeA) in mothers exhibits robust USV responses. Rabies tracing from USV-responsive neurons revealed extensive subcortical and cortical inputs into TeA. A particularly dominant cortical source of inputs is primary auditory cortex (A1), suggesting strong A1-to-TeA connectivity. Chemogenetic silencing of USV-responsive neurons in TeA impaired auditory-driven maternal preference in a pup-retrieval assay. Furthermore, dense extracellular recordings from awake mice revealed changes of both single neurons’ and population responses to USVs in TeA; improving discriminability of pup calls in mothers as compared to naïve females. These data indicate that TeA plays a key role in encoding and perceiving pup cries during motherhood.
