摘　　要：在由内部程序和外部互动所引导的发育过程中,大脑神经元会找到各自特定的位置。封面图展示的这张来自果蝇幼虫的共焦显微镜图像显示了神经元在视神经叶中的特征位置。通过免疫荧光法可以检测到,神经元是按照出生次序层叠排列的,每一层的颜色对应于神经元对转录因子的独特表达。本期特刊重点介绍了引导大脑发育背后的力量及制约因素。Neurons of the brain find their places during development guided by internal programs and external interactions. This confocal microscopy image from a Drosophila larva shows the characteristic placement of neurons in the' optic lobe. The neurons are organized in layers according to their birth order, with the color of each layer corresponding to its neurons1 unique expression of transcription factors, as detected by immunofluorescence. This special issue highlights the behind-the- scenes forces and constraints that guide brain development.
