We investigated an interaction between plasticity
processes, brain connectivity and healthy aging by
measuring levels of serum BDNF and resting-state fMRI
using eigenvector centrality (EC) mapping. The analysis
revealed a positive correlation between serum BDNF and
EC in premotor and motor regions in elderly subjects in
contrast to young subjects, where we did not detect any
association. This positive relationship between serum
BDNF and EC appears to be specific for elderly subjects.
Our results might indicate that the amount of physical
activity, leading to higher BDNF levels, increases brain
connectivity in (pre)motor areas in healthy aging in
agreement with rodent animal studies.
