Sustained attention and working memory were improved in young adults after they engaged in a recently developed, closed-loop digital meditation practice. Whether this type of meditation also has a sustained effect on dominant resting state networks is currently unknown. Here, we examined the resting brain states before and after a period of breath-...

Psychometric intelligence is closely related to working memory (WM) and the associated brain activity. We aimed to clarify the associations between psychometric intelligence and WM-induced functional connectivity changes. Here we determined the associations between psychometric intelligence measured by non-verbal reasoning (using the Raven's Advanc...

To determine the optimal number of connectivity states in dynamic functional connectivity analysis. Recent work has focused on the study of dynamic (vs static) brain connectivity in resting fMRI data. In this work, we focus on temporal correlation between time courses extracted from coherent networks called functional network connectivity (FNC). Dy...

The association between regional volumes and resting-state functional networks was tested within the default-mode network (DMN), influenced by Alzheimer's pathology, salience network (SalN), not under similar pathological influence, and sensorimotor network (SMN), usually spared by pathology. One-hundred-and-forty-eight participants, with Alzheimer...

Bilingualism is considered a cognitive reserve (CR) factor, due to the delay in the onset of dementia in bilinguals compared to monolinguals. Two neural mechanisms have been suggested to underlie CR: neural reserve and neural compensation. However, it is still unclear how bilingualism contributes to these mechanisms. In this study, we used cognitiv...

The thalamus as a key relay of neuronal information flow between subcortical structures and cortical networks, has been implicated in focal limbic seizures propagation, awareness maintenance and seizure related cognitive deficits. However, the specific functional alterations between different thalamic nuclei and subcortical-cortical systems in temp...

Working memory (WM) and its BOLD-related parametric modulation under load decrease with age. Functional connectivity (FC) generally increases with WM load; however, how aging impacts connectivity and whether this is load-dependent, region-dependent, or associated with cognitive performance is unclear. This study examines these questions in 170 heal...

It is unknown that alterations in the dynamic networks of the brain and underlying molecular pathological mechanism of Alzheimer's disease (AD) spectrum. Here, we aim to explore the association between alterations in the dynamic brain networks trajectory and cognitive decline in AD spectrum. One hundred and sixty subjects were recruited from ADNI d...

How components of the distributed brain networks that support cognition participate in typical functioning remains a largely unanswered question. An important subgroup of regions in the larger network are connector hubs, which are areas that are highly connected to several other functionally-specialized sets of regions, and are likely important for...

High variability between individuals (i.e. inter-individual variability) in response to transcranial direct current stimulation (tDCS) has become a commonly reported issue in the tDCS literature in recent years. Inherent genetic differences between individuals has been proposed as a contributing factor to observed response variability. This study i...
