Comment on Greenwood (2007): functional plasticity in cognitive aging.

In this commentary on P. M. Greenwood's Functional Plasticity in Cognitive Aging: Review and hypothesis ( 2007), the author raises a number of questions stimulated by the article. Although it may be premature to expect answers to those questions, the author argues that they ultimately need to be addressed and answered before Greenwood's speculations can be considered true hypotheses rather than a conceptual framework.
