Mother-young bonding is a type of early learning where the female and their newborn recognize each other through a series of neurobiological mechanisms and neurotransmitters that establish a behavioral preference for filial individuals. This process is essential to promote their welfare by providing maternal care, particularly in altricial species, animals that require extended parental care due to their limited neurodevelopment at birth. Olfactory, auditory, tactile, and visual stimuli trigger the neural integration of multimodal sensory and conditioned affective associations in mammals. This review aims to discuss the neurobiological aspects of bonding processes in altricial mammals, with a focus on the brain structures and neurotransmitters involved and how these influence the signaling during the first days of the life of newborns.
母婴联结是一种早期学习形式，其中雌性个体与其新生儿通过一系列神经生物学机制和神经递质相互识别，这些机制和递质建立了对幼崽个体的行为偏好。这个过程对于通过提供母性关怀来促进幼崽的福利至关重要，特别是在晚成雏物种中，这些动物由于出生时神经发育有限而需要长期的亲代照顾。嗅觉、听觉、触觉和视觉刺激触发了哺乳动物多模态感官和条件情感联想的神经整合。本综述旨在讨论晚成雏哺乳动物联结过程的神经生物学方面，重点关注涉及的脑结构和神经递质，以及这些如何影响新生儿出生后最初几天的信号传递。
