Magnetic resonance imaging (MRI) is a common physiological measure used to compare brain images between individuals with and without Alzheimer's disease. MRI can detect changes in brain structure and can pinpoint areas of atrophy or damage associated with Alzheimer's. Electroencephalogram (EEG) and electromyogram (EMG) are measures of brain and muscle activity, respectively, and are less likely to be used to compare brain images in Alzheimer's research. Galvanic skin response measures changes in sweat gland activity in response to emotional or cognitive stimuli and is also unlikely to be used to compare brain images in Alzheimer's research.
