畢律民分區（英文：Brodmann area）係一個分區系統，根據細胞結構將大腦皮層劃分為一系列解剖區域。神經解剖學入便嘅所謂細胞架構（英語： ） ，意指啲神經元嘅組織方式、喺染唨色嘅腦組織度觀察到嘅。
The Brodmann area is a partitioning system that divides the cerebral cortex into a series of anatomical regions based on cellular structure. The so-called cellular architecture in neuroanatomy refers to the way neurons are organized, as observed in stained brain tissue.
