Your brain’s a real oxygen hog. It’s a small part of your body weight, but it uses 20% of your oxygen. It can’t store the oxygen, so it needs a steady flow of blood to work well. Brain cells start to die if they go without oxygen for just 3-4 minutes — and that’s exactly what happens during a stroke.

Can brain activity be restored?

The brain can produce new cells Neurogenesis is now accepted to be a process that occurs normally in the healthy adult brain, particularly in the hippocampus, which is important for a learning and spatial memory.

Does your brain age?

As we age our brains shrink in volume, particularly in the frontal cortex. As our vasculature ages and our blood pressure rises the possibility of stroke and ischaemia increases and our white matter develops lesions. Memory decline also occurs with ageing and brain activation becomes more bilateral for memory tasks.

Can half a brain be removed?

Hemispherectomy is a very rare neurosurgical procedure in which a cerebral hemisphere (half of the brain) is removed, disconnected, or disabled.
