Question

What is the definition of hemisphere

Answer 1

Each hemisphere of the cerebrum is responsible for different brain functions, and they are connected by the corpus callosum. While some functions are localized to one hemisphere, the two hemispheres largely share functions.

Step-by-step explanation:

The term 'hemisphere' refers to each of the two halves of the cerebrum in the brain. The cerebrum is the largest part of the brain and is responsible for higher-level processes such as consciousness, thought, emotion, reasoning, language, and memory. Each hemisphere of the cerebrum can be further divided into four lobes: frontal, parietal, temporal, and occipital, which are associated with different brain functions.

The two hemispheres of the cerebrum are connected by a structure called the corpus callosum, which allows for communication and information sharing between the hemispheres.

While there are some brain functions that are localized more to one hemisphere than the other, the functions of the two hemispheres are largely redundant.

Answer 2

In geography, a hemisphere is a half of the earth, usually as divided into northern and southern halves by the equator, or into western and eastern halves by an imaginary line passing through the poles.
