需要动物模型来了解人类大脑发育的遗传、分子、细胞和网络机制。在啮齿类动物中,大量的体外和体内方法允许详细的分析和特定的实验操作,用于研究皮质生成的发育步骤顺序。神经发生、神经元迁移、细胞分化、程序性细胞死亡、突触发生和髓鞘形成在啮齿动物皮层和人类皮层中惊人地相似。出生前和出生后早期人类皮质中的自发EEG活动类似于新生啮齿动物皮质内多电极阵列记录的活动模式。这种早期活动是由丘脑激活通过间隙连接偶联的亚板驱动的局部网络产生的,该网络控制皮质柱的发育和凋亡的时空模式。这种活动的紊乱可能会引起皮质结构和功能的紊乱,导致神经和精神疾病。
Animal models are needed to gain an understanding of the genetic, molecular, cellular, and network mechanisms of human brain development. In rodents, a large spectrum ofin vitroandin vivoapproaches allows detailed analyses and specific experimental manipulations for studying the sequence of developmental steps in corticogenesis. Neurogenesis, neuronal migration, cellular differentiation, programmed cell death, synaptogenesis, and myelination are surprisingly similar in the rodent cortex and the human cortex. Spontaneous EEG activity in the pre‐ and early postnatal human cortex resembles the activity patterns recorded with intracortical multi‐electrode arrays in newborn rodents. This early activity is generated by thalamic activation of a subplate‐driven local network coupled via gap junctions, which controls the development of cortical columns and the spatio‐temporal pattern of apoptosis. Disturbances of this activity may induce disturbances in cortical structure and function leading to neurological and psychiatric disorders.
