Adult Development and Aging. Review Questions: The Neuroscience Approach: (2.1) 1.Describe structural and functional neuroimaging techniques. How do they differ? Allow us to see inside the brain of a living person to examine the various structures of the brain. Neuroimaging is a set of techniques in which pictures of the brain are taken in various ways to provide understanding of both normal and abnormal cognitive aging. Structural neuroimaging provides highly detailed images of anatomical features in the brain. The most commonly used are X-rays, computerized tomography (CT) scans, and magnetic resonance imaging (MRI). Images from structural neuroimaging techniques are like photographs in that they document what a specific brain structure looks like at a specific point in time. Structural neuroimaging is usually effective at identifying such things as bone fractures, tumors, and other conditions that cause structural damage in the brain, such as strokes. Functional neuroimaging provides an indication of brain activity but not high anatomical detail. The most commonly used neuroimaging techniques

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
