Functional magnetic resonance imaging (fMRI) _________ cannot detect brain activity when odors are present can reveal differences in the amounts of oxyhemoglobin in a region of the brain detects signals that originate primarily from the electrons in water molecules and are altered by the magnetic properties of hemoglobin is a useful tool for detecting constriction of blood vessels in the more active areas of the brain

In which of the following ways does functional magnetic resonance imaging (fMRI) detect the functioning of the brain? It exploits changes in blood oxygen that occur in association with brain activity. It measures the amount of glucose in various areas of the brain. It places electrodes on the scalp to detect brain-wave activity. It establishes a cause-effect relationship between variables associated with brain activity

fMRI stands for functional magnetic resonance imaging, which is a neuroimaging technique that monitors changes in the brain and is less expensive and less risky than other techniques. It also helps to track oxygen levels and blood flow. An fMRI is "a modified version of MRI based on hemoglobin (the blood protein that binds oxygen) instead of water." fMRI's are noninvasive, and only metal objects need to be removed prior to scanning. BOLD signal stands for blood oxygen level dependent.
