Cerebro-cerebellar pathways for verbal working memory

Verbal working memory involves holding verbal information in short-term memory. Two cerebro-cerebellar networks for verbal working memory have been proposed: (1) fronto-superior cerebellar network associated with controlling and updating …

Working memory, age and education: A lifespan fMRI study

Our brain changes in terms of mental functions and its structures as we age. In this study, we examined age-related differences in brain functions while accounting for changes seen in the brain structures in terms of neuronal density and volume. …

Functional connectivity of resting-state, working memory and inhibition networks in perceived stress

In this study, we examined the relationship between perceived stress and brain functioning in women and men. Using functional magnetic resonance imaging (fMRI), brain connectivity of 22 women and 24 men were imaged when they completed two tasks in a …

The role of regional heterogeneity in age-related differences in functional hemispheric asymmetry: an fMRI study

Some cognitive functions, such as language processing, utilize one side of the brain more than the other. This pattern of brain organization is known as brain lateralization. However, studies have suggested that brain lateralization is less prominent …

Modality specificity in the cerebro-cerebellar neurocircuitry during working memory

Previous studies have suggested cerebro-cerebellar circuitry in working memory. The present fMRI study aims to distinguish differential cerebro-cerebellar activation patterns in verbal and visual working memory, and employs a quantitative analysis to …

A comprehensive analysis of connectivity and aging over the adult life span

Aging has been associated with decreased intra- and internetwork connectivity during rest and task. Recent work has shown the influential role of the salience network over the default mode network (DMN) and executive control network (ECN). This study …

Temporal dynamics of visual working memory

The involvement of the human cerebellum in working memory has been well established in the last decade. However, the cerebro-cerebellar network for visual working memory is not as well defined. Our previous fMRI study showed superior and inferior …
