How does an MRI allow the exploration of "inner space" without the injection of chemicals?
What will be an ideal response?
A good answer will include the following key points:
• Magnetic resonance imaging (MRI) uses powerful magnetic fields and radio frequencies to take highly detailed pictures of the brain.
• The magnets produce vibrations in the nuclei of atoms in the body's organs.
• The vibrations are then detected as signals by special receivers.
• A computer analyzes the signals, taking into account their strength and duration, and converts them into a high-contrast picture of whatever organ the scientist or physician is interested in, such as the brain.
• This is a structural MRI; it gives us a terrific picture of what the brain
• looks like, but not what it does.
