Age-related declines in behavior and cognition were reported as a dominant picture of the aging mind. Compelling evidence from the burgeoning field of cognitive neuroscience of aging, however, urges a reconsideration of this pessimistic view. In this article, we review the number of reports on the cognitive neuroscience of aging, focusing on a variety of neuroimaging technology, such as structural and functional magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI). In the face of the declines with age in brain structure volume, cortical thickness, and white matter integrity, functional neuroimaging studies have demonstrated increased neural activation in prefrontal and parietal regions across different cognitive domains in older adults. These results suggest that the aging brain retains considerable plasticity of function and is adaptive in response to cognitive challenges posed by structural deterioration. We review the converging evidence that is stimulating new hypotheses regarding the neural mechanisms underlying age-related changes in neurocognitive function. The current trends, unsolved issues and future directions in the cognitive neuroscience of aging are discussed.
