The MOST Basic Brain Parts

You can think of the brain into 2 general parts for Cerebrum and Cerebellum.

The cerebrum is the largest part of the human brain. It is associated with thinking, perceiving, planning, and understanding language.

This cerebrum is divided into two hemispheres- the left and right. Bridging those two hemispheres is a bundle of fibers called the corpus callosum. The two hemispheres communicate to each other through this bridge.

There is a sheet of tissue called the cerebral cortex that covers the outermost layer of the cerebrum. It is referred to as gray matter. The brain’s wrinkled appearance can be attributed to characterisitcs of the cerebal cortex. The grooves increase surface area, allowing inclusion of many more neurons.

Explain in more detail about these grooves.

Grooves of the brain

As promised earlier, I’ll explain about the grooves of the brain. The grooves are very important because they increase the brain’s surface area, allowing many more neurons to be included.

The top part of the groove is called gyrus and the bottom part is called sulcus. A deep indentation is called “fissure”. The fissure is a deeper indentation than normal wrinkles.
