How do Scientists Study the Brain?The Scientific Method
Scientists who conduct experiments to learn about the brain are called neuroscientists, and like all scientists, they use the scientific method. A fact sheet for students grades 6-8
What is Addiction?
The brain is a network of cells called neurons and glia. Approximately 86 billion neurons make up the many interconnected parts of the brain. They signal together like a symphony to help us navigate our world. While exercise, eating right, and keeping the mind engaged can help the brain stay healthy.
