TL;DR: The Cam-CAN Stage 2 repository contains multi-modal (MRI, MEG, and cognitive-behavioural) data from a large, cross-sectional adult lifespan (18–87 years old) population-based sample, providing a depth of neurocognitive phenotyping that is currently unparalleled, enabling integrative analyses of age-related changes in brain structure, brain function, and cognition.

TL;DR: Because this project focuses on normal age-related changes, the results may contribute to changing views about the ageing process, lead to targeted interventions, and reveal how normal ageing relates to frail ageing in clinicopathological conditions such as Alzheimer's disease.

TL;DR: A model wherein aging weakens connections among linguistic representations, thereby reducing the transmission of excitation from one representation to another is described, which makes them vulnerable to transmission deficits, impairing retrieval.

TL;DR: For example, Kemper et al. as discussed by the authors found that the aging pattern is characterized by stability and improvement during adulthood in some language functions, unlike other cognitive abilities such as episodic or working memory which are characterized by quite uniform age-related decrements.

TL;DR: It is argued that preserved syntactic processing across the life span is due to the shift from a primarily left hemisphere frontotemporal system to a bilateral functional language network.
