人类医学对脑的研究从宏观到微观,从形态到机能已有大量记载,如脑的形态、沟回、重量、大小、大脑皮层的平均厚度、面积、脑的神经细胞数,以及采用现代最先进的物理化学方法从各种水平对脑的结构与功能进行着大量的基本理论研究。目前在临床上对新生儿头颅的发育儿科仍以头围和身长与头长之比做为生理指标,其间也包括着脑的发育。 Human medicine research on the brain from the macro to the micro, from morphology to function has been recorded in large quantities, such as brain morphology, ditch back, weight, size, the average thickness of the cerebral cortex area, the number of brain cells, and the use of modern Advanced physical and chemical methods from a variety of levels on the brain structure and function of a large number of basic theoretical research. At present, the development of pediatric head of newborns in the clinic is still head circumference and body length and head length ratio as a physiological indicator, which also includes the development of the brain.
