Answer: Functional magnetic resonance imaging (fMRI)
Explanation: Whether in the right or left hemisphere, increased brain activity associated with increased blood flow is measured by functional magnetic resonance imaging (fMRI) or functional MRI. This technique is based on the fact that the activation of neurons in the brain is related to blood flow also in the brain. When the brain is strained by some perceptual task, that is, the part of the brain responsible for some perceptual function, then the blood flow through that part of the brain increases. This again means a change in the magnetic image being recorded, due to the fact that the blood carries certain charges and with their increase that can be recorded, and due to the activity of the part of the brain, the increased activity of neurons can be measured.
