The brain is the command center of the nervous system and supports all the body systems and functions.
The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It receives and sends signals all over the body to keep you safe and healthy.
The brain supports learning and cognition and stores memories.
Just like all our other organs, the brain can become diseased either because of trauma, an excess of damaging molecules (toxins and excess of sugar) or organisms (chronic infection and dysbiosis/imbalance in the normal flora). A lack of what it needs to function and repair leaves the brain vulnerable.
The brain does have the ability to heal (regenerate) and form new brain cells. This means that you can keep your brain healthy and all its functions optimal.
Repair occurs as a result of neuroplasticity and with the support of brain-derived neurotrophic factor (BDNF).
