Brain Connectivity Related to Working Memory Performance

Investigating the functional connectivity between the PCC and MFG/vACC during a working memory task and at rest by examining temporal correlations in magnetic resonance signal levels found the two regions were functionally connected in both conditions.

Cognitive and Emotional Modulation of Brain Default Operation

The results indicate that task-related decreases may be further modulated by the emotional stimulus connotation, and are consistent with the previously reported effect of task difficulty on task- related brain activation decreases.


The correlation coefficient between the electrical signal at different locations of the EEG and the BOLD signal from fMRI representative of thedefault network did not confirm the presence of EEG patterns associated with the default network in the resting state and the need to improve certain technical aspects of simultaneous record EEG / fMRI is concluded.

Impact of Working Memory Load on fMRI Resting State Pattern in Subsequent Resting Phases

Evidence is presented that a cognitively challenging working-memory task is followed by greater activation of the DMN than a simple letter-matching task, which might be interpreted as a functional correlate of self-evaluation and reflection of the preceding task or as relocation of cerebral resources representing recovery from high cognitive demands.

Functional Imaging of Working Memory after 24 Hr of Total Sleep Deprivation

The neurobehavioral effects of 24 hr of total sleep deprivation on working memory in young healthy adults was studied using functional magnetic resonance imaging and neural correlates provide neural correlates to explain why task performance in relatively more complex tasks is better preserved relative to simpler ones after SD.

Functional connectivity in the resting brain: A network analysis of the default mode hypothesis

This study constitutes, to the knowledge, the first resting-state connectivity analysis of the default mode and provides the most compelling evidence to date for the existence of a cohesive default mode network.

Spontaneous Brain Activity in the Default Mode Network Is Sensitive to Different Resting-State Conditions with Limited Cognitive Load

The findings of the higher DMN connectivity and regional spontaneous activities in the resting state with the eyes open suggest that the participants might have more non-specific or non-goal-directed visual information gathering and evaluation, and mind wandering or daydreaming during the restingState with theeyes open as compared to that with the Eyes closed, thus providing insights into the understanding of unconstrained mental activity within the DMN.



Functional Anatomy of Spatial Mental Imagery Generated from Verbal Instructions

Results provide evidence that the so-called dorsal route known to process visuospatial features can be recruited by auditory verbal stimuli and confirm previous reports indicating that some mental imagery tasks may not involve any significant participation of early visual areas.

Functional mapping of brain areas implicated in auditory--verbal memory function.

Brain regions showing increases in rCBF in these comparisons included the thalamus, left anterior cingulate, right parahippocampal gyrus, cerebellum and the superior temporal gyrus.

Cortical anatomy of mental imagery of concrete nouns based on their dictionary definition

It is demonstrated that a network including part of the bilateral ventral stream and the frontal working memory areas is recruited when mental imagery of concrete words is performed on the basis of continuous spoken language.

Conceptual Processing during the Conscious Resting State: A Functional MRI Study

A model that proposes that perceptual tasks interrupt processes ongoing during rest that involve many of the same brain areas engaged during semantic retrieval may help to explain several unanticipated results from prior studies of semantic processing.

Regional brain activity during tasks devoted to the central executive of working memory.

Human cerebellum plays an important role in memory-timed finger movement: an fMRI study.

The results indicate that the anterior lobe of the cerebellum of both sides, the SMA, and the left prefrontal cortex were probably involved in the generation of accurate timing, functioning as a clock within the CNS, and that the dorsal visual pathway may be involved inThe generation of visually cued movements.

The Mind's Eye—Precuneus Activation in Memory-Related Imagery

Memory-related imagery was associated with significant activation of a medial parietal area, the precuneus, which provides strong evidence that it is a key part of the neural substate of visual imagery occurring in conscious memory recall.

The Large-Scale Neural Network for Spatial Attention Displays Multifunctional Overlap But Differential Asymmetry

Both exogenous (based on spatial priming) and endogenous ( based on expectancy cueing) shifts of attention are subserved by a common network of cortical and subcortical regions, however, the differences between the two tasks, especially in the degree of rightward asymmetry, suggests that the pattern of activation within this network may show variations that reflect the specific attributes of the attentional task.

Visual memory, visual imagery, and visual recognition of large field patterns by the human brain: functional anatomy by positron emission tomography.

The areas of the human brain that changed rCBF during the storage, retrieval from long-term memory, and recognition of complex visual geometrical patterns were mapped to indicate that the ways by which the brain accesses the storage sites are different.

Imaging Cognition II: An Empirical Review of 275 PET and fMRI Studies

Analysis of regional activations across cognitive domains suggested that several brain regions, including the cerebellum, are engaged by a variety of cognitive challenges.
