Course Prerequisites:  

1.  A graduate course in physiological psychology or basic neuroscience.

2.  A graduate intro course in cognitive psychology

3.  Some basic knowledge of gross neuroanatomy.
   


Course Description:  

Deciphering the secret of successful aging depends on understanding the patterns of cognitive and behavioral change throughout adulthood.  In this course, we will examine the extant literature on age-related differences and changes in the neuroanatomy. We will summarize the findings from postmortem studies, and cross-sectional and review longitudinal magnetic resonance imaging studies of whole-brain and regional anatomy, including volumetry, diffusion-tensor imaging, and evaluations of white matter hyperintensities. Further, we will review the literature on metabolic markers of aging. We will discuss the putative links between the pattern of brain aging and the pattern of cognitive decline and stability. We will discuss the examples of activities and conditions (hypertension, hormone deficiency, aerobicfitness) that may influence the course of normal aging in a positive or negative fashion.  Lastly, we will speculate on several proposed mechanisms of differential brain aging and its links to cognitive changes in late-life development.
