1. According to what we know today, which of the following is true about brain development:
a. Neuronal populations and their connections (the basic architecture of the brain are established during the prenatal period
b. Soon after birth, oligodendrocytes proliferate, differentiate, and wrap the connecting axons with insulating, fatty sheaths of myelin
c. Little additional growth of the brain occurs after age 5 or 6.
d. Brain development is dynamic throughout much of childhood, up to age 20
e. None of the above are true
2. Brain morphometry is a way to:
a. quantify certain parameters of neural architecture to see subtle changes over time
b. image brain function and metabolism with great temporal resolution
c. image brain function and metabolism with great spatial resolution
d. measure cortical oscillations from the scalp as they change
e. none of the above
3. The PING study included
a. patients with Alzheimer’s disease
b. nondemented older adults
c. longitudinal data as people aged up to 20 years old
d. cross sectional data across different ages up to 20 years old
e. a mixture of cross sectional and longitudinal data
4. Diffusion tensor imaging shows us:
a. brain function and metabolism with great spatial resolution
b. brain function and metabolism with great temporal resolution
c. directionality of diffusion of water molecules in the brain
d. changes in cortical oscillations as measured from the scalp
e. none of the above
5. In Dr. Jernigan’s study if behavioral individual differences in Danish children, involving a stop signal task, the main finding was that:
a. individual differences in performance on the task were associated with differences in fiber tract maturation in the presupplemental motor area and the inferior frontal gyrus
b. individual differences in performance on the task were associated with differences in fiber tract maturation in the subthalamic nucleus
c. a decrease in performance in older children
d. all of the above
e. none of the above
