Aging

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Area of Science:

Neuroscience
Cognitive Science
Aging Research

Background:

The relationship between brain structure and function is complex and not fully understood.
Healthy aging involves heterogeneous changes in structural integrity affecting functional network dynamics.

Purpose of the Study:

To investigate the association between structural and functional brain connectivity patterns.
To explore how this association relates to cognitive performance in healthy older adults.

Main Methods:

Utilized multilayer brain network analysis.
Employed structural (diffusion-weighted imaging) and functional (magnetoencephalography) data from the Cam-CAN database.

Main Results:

Found a significant association between the similarity of structural and functional connectivity patterns in parietal and temporal regions (alpha frequency band) and cognitive performance.
Highlighted the impact of structural changes on functional connectivity reorganization.

Conclusions:

Structural connectivity changes influence functional network reorganization, contributing to cognitive preservation in aging.
The structure-function link may serve as a marker for individual variability and pathological changes in aging.
