Neuroplasticity01:01

Neuroplasticity

2.6K
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Aging01:26

Aging

1.1K
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...

Alzheimer's Disease: Overview

1.7K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Gut-Brain Axis01:22

Gut-Brain Axis

249
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...

Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

1.4K
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Alzheimer Disease l: Introduction01:29

Alzheimer Disease l: Introduction

29
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Area of Science:

  • Neuroscience
  • Network Science
  • Gerontology

Background:

  • Understanding age-related changes in brain function is crucial for cognitive health.
  • Network science offers a novel approach to model brain interactions.

Purpose of the Study:

  • To investigate age differences in functional brain network topology.
  • To explore the relationship between network organization, cognitive abilities, and well-being in older adults.

Main Methods:

  • Applied network science to model functional interactions between brain regions.
  • Analyzed changes in network topology across different age groups.

Main Results:

  • Older adults exhibited increased connectivity of subcortical and cerebellar regions within the Salience network.
  • Fragmentation of large-scale cortical networks (Default, Fronto-Parietal) was observed in older adults.
  • Enhanced Salience network integration correlated with higher life satisfaction, and Default Network coherence with faster processing speed.

Conclusions:

  • Normal aging is associated with significant shifts in large-scale brain network organization.
  • These network alterations provide insights into age-related cognitive and emotional well-being differences.
