This film gives a overview of the structure and function of the brain.

TRANSCRIPT
"The human brain is incredibly complex. It controls everything our body does, from coordinating our movements and our speech, to keeping our heart beating, to storing our memories. Despite all this there is still a lot we don't know and much of the brain's inner workings are still a mystery.

The average human brain weighs around 1.5 kg.

It is fed by a network of blood vessels that provide the brain cells with oxygen and nutrients.

The brain can be divided into four main sections - the cerebral cortex, which is split into two symmetrical cerebral hemispheres, the limbic system, the cerebellum and the brain stem.

The bulk of the brain is the symmetrical cerebral cortex. Each cerebral hemisphere is separated into four main lobes, which have different functions. The frontal lobe is responsible for decision-making, problem solving and planning. The parietal lobe receives and processes all the sensory information from the body. The temporal lobe is responsible for memory, emotion, hearing and language. The occipital lobe controls vision.

At the centre of the brain is the limbic system. This area controls a number of functions, but importantly controls learning and memory, particularly in the hippocampus.

The cerebellum or little brain, controls movement, posture and balance.

The brain stem, which is thought to be the oldest part of the brain, controls basic life functions like heart beat, breathing and blood pressure."


Please watch our other videos to see how brain cells function, hear what dementia is, and to hear more about Alzheimer's disease, Posterior Cortical Atrophy, vascular dementia, dementia with Lewy bodies, fronto-temporal dementia and other rarer causes of dementia.

Alzheimer's Society is dedicated to defeating dementia through research. Our unique research programme funds research into the cause, cure, care and prevention of dementia to improve treatment for people today and to search for a cure for tomorrow.

We are the only organisation to work with leading scientists and people affected by dementia to ensure our research influences practice and transforms lives. With the right investment, dementia can be defeated.
