一隻成年獼猴嘅腦嘅橫切面;最外深紫色嗰浸就係大腦皮層。

用高基方法染咗色嘅大腦皮層神經細胞。
大腦皮層(粵拼:daai6 nou5 pei4 cang4;英文:cerebral cortex)係人同埋第啲哺乳類動物嘅大腦(cerebrum)最外面嗰浸神經組織(指由神經細胞同膠質細胞組成嘅組織),喺人當中主要由六層嘅新皮層(neocortex)組成,由中央縱裂(longitudinal fissure)分做左腦同右腦[1]。
喺多數哺乳類動物當中(除咗一啲個腦細嘅細隻哺乳類之外),大腦皮層表面都好皺,令到塊大腦皮層喺容量受(頭殼嘅)限制下能夠有最大嘅表面積,容納最多嘅神經細胞同有最大嘅資訊處理能力[2]。因為佢嘅龐大資訊處理能力,大腦皮層係成個中央神經系統裏面最大嘅神經訊號整合中心,對感知、注意力、思緒、記憶、語言同意識等嘅認知功能嚟講不可或缺[3]。
腦葉[編輯]
按照廿一世紀嘅神經科學,大腦皮層可以分做四大腦葉:
