The Brain
Biology: AQA GCSE Higher, topic 5.2.7
The Brain
The brain is a very complex organ that controls all conscious and unconscious thoughts in order to keep an organism alive.
Brain function
- The brain is made up of millions of interconnecting neurones (nerve cells).
- Different regions of the brain are responsible for coordinating (organising) different functions.
Brain damage
- The brain is delicate, complex, and not well understood.
- Therefore, the treatment of brain damage and brain disease is difficult.
Test yourself on The Brain
Why is it hard to treat brain damage or problems in the brain?
Why does the brain control both conscious and unconscious thoughts?
How do neurones in the brain create its many functions?
Why might damage to one region of the brain affect only certain abilities, rather than all of a person's abilities?
Why is the brain considered a complex organ?
