What is the biggest part of the brain?
The largest part of the human brain is the cerebrum.
The cerebrum is responsible for a wide array of functions, including:
- Initiating and coordinating movement
- Regulating temperature
- Higher-level cognitive functions like thinking, learning, and memory
It's composed of two hemispheres connected by a band of tissue. The cerebrum's outer layer, the cerebral cortex, is made up of gray matter, while the inner part contains white matter. Multiple sources confirm the cerebrum's status as the brain's largest component. (Cleveland Clinic, KidsHealth, Mayfield Clinic, Byju's, Byju's, Study.com, Mayo Clinic)
While other brain parts like the cerebellum and brainstem are crucial, their size pales in comparison to the cerebrum. The cerebrum's dominance in size reflects its crucial role in higher-order brain functions.
