the brain

What makes up the central nervous system

The brain and spinal cord

What is the brain in charge of

All our complex behaviours it controls everything you do and makes all the important decisions

What are the different regions of the brain and what are they responsible for

Cerebral cortex- the wrinkly layer of Brain responsible for consciousness, intelligence , memory , language

Cerebellum- back of the brain responsible for controlling our balance and muscle coordination

Medulla- within the brain stem controls our unconscious activities like breathing and heart beating

Why is treating the brain so difficult

1- wide range of things could go wrong e.g. tumours , infection, trauma, mental health illness

2-in cased within skull surrounding brain tissue is fragile so extremely it difficult to physically fix anything

3- the brain is so complex - don’t fully understand difficult to fix anything with drugs and chemicals v cause we don’t understand the underlying processes

What are the 3 ways scientists can study the brain

1-studying people with brain damage

2- electrically stimulate different parts of brain(using electrode )

3- scanning the brain - CT scans using X-rays , Pet scans using radioactive chemicals , MRI scans using magnetic fields

What’s the difference between CT scans and Pet and MRI scans

CT scans are mainly used to see what areas of the brain are damaged

Pet and MRI cans are better at measuring the underlying activity of the brain
