The human brain contains approximately 86 billion neurons
The brain accounts for around 2% of body weight, yet uses 20% of the body’s energy
During early childhood the brain uses around 50% of the body’s energy
For the brain to maintain optimal function, three main cell types - neurons, astrocytes and microglia - must all work correctly. While astrocytes and microglia are important in supporting the function of neurons, it is the neurons themselves that are directly associated with memory, learning, and cognitive function.
These neurons transmit information from the body’s senses (such as vision, smell, touch) via sensory neurons, and then process this information by sharing it across different areas of the brain. The brain then sends signals to the body via motor neurons (to muscles, and organs such as the heart and liver) where physical responses, such as muscle movement, take place.
These processes are potentially modifiable, and can be supported through different lifestyle factors. At Brain Health Network, we want to help people make sustainable lifestyle change to maintain a healthy brain. Find out more on our Simple Steps page.
