Each cerebral hemisphere has four lobes namely frontal lobe, parietal lobe, occipital lobe and temporal lobe.

每个大脑半球有四个脑叶，即额叶、顶叶、枕叶和颞叶。

The most obvious is the cerebrum, which is divided into two cerebral hemispheres, each of which has a cortex, or an outer region, divided into four lobes, including the frontal lobe, parietal lobe, temporal lobe, and the occipital lobe.

最明显的就是大脑：大脑分为左右两个半球；左右半球的皮质，即最外面的区域，都可再分为四叶：额叶、顶叶、颞叶和枕叶。
