The Brains


The brain is responsible for complex behaviours

>Along with the spinal cord, the brain is part of the central nervous system.

>It is made up of billions of cinterconnected neurons. 

>The brain is in charge of all complex behaviours. It controls and coordinates everything you do.

Different regions carry out different tasks

Cerebal Cortex-This is the wrinkley bit. It is responsible for things like consciousness, intelligence, memory and language.

Medulla-Controls unconsciousness activities like breathing and your heartbeat.

Cerebellum-Responsible for muscle coordination

Scientists use many methods to study the brain

Studying patients with brain damage

>If a small part of your brain has been damaged, the effect this has on the patient can tell you alot about what the damaged part of the brain does.

Electrically stimulating the brain

>The brain can be stimulated electrically by pushing tiny electrode into the tissue and giving it a small zap of electricity. By observing what stimualting different parts of the brain does, it's possible to get an idea of what those parts do.

MRI Scan

>A magnetic resonance imaging scanner is a big machine that produces a very detailed photographof the brain's structures. Scientists use it to find out what areas of the brain are active when people are doing things like listening to music or trying to recall a memory.

Messing with the brain can have consequences

>Knowledge of the brain works has led to the development of treatment for disorders of the nervous system.

>For Example-Electricla stimulation of the brain can help reduce muscle tremors caused by nervous system disorders such as Parkinson's disease.

>However, the brain is incredibly complex and delicate-the investigation if brain function and any treatment of the brain damge or disease is difficult. It also carries risks, such as physical damage to the brain or increased problems with brain function
