We tested the hypothesis that aging is associated with an impaired contraction-induced rapid vasodilation in healthy adults. We reasoned that employing single contractions of a small muscle mass would allow us to isolate the local rapid vasodilatory responses independent of systemic hemodynamic and sympathetic neural influences on forearm hemodynamics. We ...

It is unclear whether older adults of different race or ethnicity vary in the ways they perceive functional limitations. Variation in such self-reports may be relevant clinically, because many diagnoses (and subsequent care) depend on self-reported disability. To examine this question, self-reported hand function was compared with performance-based assessment of ...

Normal aging is associated with less lateralised task-related activation of the primary motor cortices. It has been hypothesized, but not tested, that this phenomenon is mediated transcallosaly. We have used Transcranial Magnetic Stimulation to look for age-related changes in interhemispheric inhibition (IHI). Thirty healthy individuals (aged 19-78 years) were studied ...
