Differences between the cerebellum and the cerebrum

The differences between the cerebellum and the cerebrum are mainly reflected in size, location, function, and other aspects.

1. Size

The most noticeable difference lies in their size. The cerebrum accounts for approximately 85% of the total volume of brain tissue and is the largest region of the brain. It consists of two cerebral hemispheres, each divided into four parts: the temporal lobe, parietal lobe, occipital lobe, and frontal lobe. In contrast, the cerebellum is much smaller, making up only about 10% of the total brain volume. It comprises two cerebellar hemispheres and a central vermis.

2. Location

The cerebellum and cerebrum are separated by the dura mater and located in different areas. The cerebrum occupies the upper portion of the brain, while the cerebellum is situated directly beneath the cerebrum, in the posterior-inferior region of the cranial cavity.

3. Function

The cerebrum is responsible for higher cognitive functions such as attention, judgment, logical thinking, and learning. The cerebellum primarily regulates muscle movement and coordination. Although their functions differ, they complement each other to some extent and cannot operate independently.
