The effect of ageing on f MRI: Correction for the confounding effects of vascular reactivity evaluated by joint f MRI and MEG in 335 adults
In functional magnetic resonance imaging (fMRI) research one is typically interested in neural
activity. However, the blood‐oxygenation level‐dependent (BOLD) signal is a composite …

Extrinsic and intrinsic brain network connectivity maintains cognition across the lifespan despite accelerated decay of regional brain activation
The maintenance of wellbeing across the lifespan depends on the preservation of cognitive
function. We propose that successful cognitive aging is determined by interactions both …

Challenges in measuring individual differences in functional connectivity using fMRI: the case of healthy aging
… The details of this procedure, including methods of outlier detection are described in Tsvetanov
et al. [2015]. LF and HF-HRV were log-transformed to obtain more normal distributions. …

[HTML][HTML] Noradrenergic-dependent functions are associated with age-related locus coeruleus signal intensity differences
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. …

[HTML][HTML] Ageing increases reliance on sensorimotor prediction through structural and functional differences in frontostriatal circuits
The control of voluntary movement changes markedly with age. A critical component of motor
control is the integration of sensory information with predictions of the consequences of …

KL Campbell, MA Shafto, P Wright, KA Tsvetanov… - Neurobiology of …, 2015 - Elsevier
Much is known about how age affects the brain during tightly controlled, though largely contrived,
experiments, but do these effects extrapolate to everyday life? Naturalistic stimuli, such …
