Does the default mode functional connectivity of the brain correlate with working memory performances?

Does the default mode functional connectivity of the brain correlate with working memory performances?

This approach has revealed the surprising finding that working memory performance is positively related to functional connectivity in the so-called default mode network (as measured both at rest and during task performance). This suggests that these areas may be part of a network that facilitates cognitive performance.

What are the brain mechanisms of working memory?

WM consists of four subcomponents: a central executive system for attentional control, a phonological loop for the storage and manipulation of verbal materials, a visual-spatial sketchpad for object and spatial information, and an episodic buffer for storage of information (Baddeley, 2003).

What does brain connectivity do?

Brain connectivity is operationally defined as the estimation of the relation between brain areas (Regions of interest, ROIs, or Volumes of interest, VOIs); these relations are established when a specific cognitive task is being solved or when resting.

Does brain connectivity change?

The dynamic of the temporal correlations between brain areas, called functional connectivity (FC), undergoes complex transformations through the life span. Studies suggest that these processes are in line with the development of cognitive and sensory functions throughout life as well as their deterioration.

What influences working memory?

Here are 5 factors that can influence the functioning of the memory:

  • The degree of attention, vigilance, awakening and concentration.
  • Interest, motivation, need or necessity.
  • The emotional state and emotional value attributed to the material to be memorized.

What are the three main types of connectivity in the brain that can be measured using MRI FMRI?

The brain connectome can be understood using many measures of connectivity of distinct nature: structural (using imaging techniques such as T1 and diffusion magnetic resonance imaging (MRI)), functional (using functional imaging such as positron emission tomography and functional MRI) as well as neuronal (using scalp …

What is the concept of connectivity?

Definition of connectivity : the quality, state, or capability of being connective or connected connectivity of a surface especially : the ability to connect to or communicate with another computer or computer system.

Which part of the brain is responsible for working memory?

the prefrontal cortex
What is this? The team looked at studies of the prefrontal cortex, an area of the brain that is crucial for working memory. Damage to this area of the brain can affect memory and our ability to perform tasks.

How do you improve working memory?

You can help your child improve working memory by building simple strategies into everyday life.

  1. Work on visualization skills.
  2. Have your child teach you.
  3. Try games that use visual memory.
  4. Play cards.
  5. Encourage active reading.
  6. Chunk information into smaller bites.
  7. Make it multisensory.
  8. Help make connections.

What is structural connectivity?

Structural connectivity is defined as the existence of white matter tracts physically interconnecting brain regions and is typically measured in vivo in humans using diffusion weighted imaging.

Can emotional working memory training alter the EEG microstate in anxiety?

Is functional connectivity for a large part predetermined?

Networks of functional connectivity are highly consistent across participants, suggesting that functional connectivity is for a large part predetermined. However, several studies have shown that functional connectivity may change depending on instructions or previous experience.

What are the task‐relevant neural networks in the brain?

We focused on two task‐relevant networks, the frontoparietal network and the default network, using seed regions in the right middle frontal gyrus (MFG) and the medial prefrontal cortex (PFC), respectively.
