Neurons do not touch each other, but where one neuron comes close to another neuron, a synapse is formed between the two. According to new research, the human brain contains around 86 billion neurons (Herculano-Houzel, 2009). Brain cells begin to die in minutes. Another type of stroke is a hemorrhagic stroke. It occurs when a blood vessel in the brain leaks or bursts and causes bleeding in the brain. The blood increases pressure on brain cells and damages them. A stroke is a medical emergency. It's crucial to get medical treatment right away.
