Which functions is the left hemisphere mainly responsible for?

The left hemisphere controls language, including speech and reading, in most people. The left hemisphere also handles logical and analytical thinking.

Which functions is the right hemisphere mainly responsible for?

The right hemisphere is mainly responsible for spatial skills and recognising faces. The right hemisphere also processes emotion and music.

Which side of the body does each hemisphere control?

Each hemisphere controls the opposite side of the body. The left hemisphere controls movement of the right hand.

What is the corpus callosum and what is its role?

The corpus callosum is a thick bundle of nerve fibres joining the two hemispheres. The corpus callosum passes information between the left and right hemispheres.

Questions from this subtopic

Each one with the model answer underneath.

1
What is lateralisation of function?
Model answer
Lateralisation is the idea that the two hemispheres of the brain specialise in different functions.
2
What is meant by asymmetrical function in the brain?
Model answer
Asymmetrical function means the left and right hemispheres do not do exactly the same jobs.
3
