abstract = {The locus coeruleus (LC), the origin of noradrenergic
modulation of cognitive and behavioral function, may play an
important role healthy ageing and in neurodegenerative
conditions. We investigated the functional significance of
age-related differences in mean normalized LC signal
intensity values (LC-CR) in magnetization-transfer (MT)
images from the Cambridge Centre for Ageing and Neuroscience
(Cam-CAN) cohort - an open-access, population-based dataset.
Using structural equation modelling, we tested the
pre-registered hypothesis that putatively noradrenergic
(NA)-dependent functions would be more strongly associated
with LC-CR in older versus younger adults. A unidimensional
model (within which LC-CR related to a single factor
representing all cognitive and behavioral measures) was a
better fit with the data than the a priori two-factor model
(within which LC-CR related to separate NA-dependent and
NA-independent factors). Our findings support the concept
that age-related reduction of LC structural integrity is
associated with impaired cognitive and behavioral function.},
