Overall, there is considerable shrinkage that occurs in the aging brain.However, the shrinkage is selective.The prefrontal cortex, the _______ , and the __________ all show profound shrinkage.

The effective functioning of the dopaminergic system _________ in normal aging.

The ________________ is the outermost part of the brain.It consists of two hemispheres (the right and the left), which are connected by the corpus callosum.

The two neuroimaging techniques that are most often used provide

Bone fractures, tumors, and other conditions that can cause structural damage in the brain are typically detected by the use of _______________.

The scaffolding networks used by older adults are __________ than the honed, focal ones they used as young adults.

Structural brain changes have been linked to executive function.For example, age-related declines in ___________may affect white matter structures, which underlie all the areas important to executive functioning.

Which of the following is associated with neuroscience?

Aside from dopamine, serotonin and acetylcholine are two other important ______________ related to cognitive aging.

Which approach compares the brain functioning of healthy older adults with adults displaying various pathological disorders of the brain?

SPECT and PET are examples of

Across the research, the typical finding is that older adults have reduced brain activity in the _________ areas when compared with younger adults.

The ___________ are involved in higher-order executive functions such as the ability to make and carry out plans, switch between tasks, and maintain attention and focus.

Which of the following are older adults more motivated to maintain?

The _______________approach allows for real-time investigation of changes in brain function as they affect cognitive performance in older adults.

Can exercise actually improve one's cognitive skills? Cite examples from research to support.

Key structural, or anatomical, features of the neuron include all the following except

For adult development and aging research, the most important elements of the limbic system are the

Erikson and colleagues (2009) were interested in whether aerobic exercise had any effect on the volume of the hippocampus, a key brain structure related to memory.To assess this, they had older adults
