The researchers also administered resting - state functional MRI to assess functional brain connectivity within each study participant.

Not exact matches

She «found greater neural connectivity from front to back and within one hemisphere in males, suggesting their brains are structured to facilitate connectivity between perception and coordinated action.

The latest work paints a picture of LSD and some other hallucinogens as drugs that can decrease modularity and connectivity within brain networks while enhancing the brain's overall connectivity, explains Frederick Barrett, a cognitive neuroscientist at Johns Hopkins University who has studied hallucinogenic drug effects but was not involved in the research released this week.

My main goals are: a) to unravel the functional and anatomical connectivity of the primate prefrontal cortex circuitry within the framework of complex cognitive tasks, b) to generate tools and techniques that allow manipulating prefrontal cortex function and therefore generate symptoms of mental disorders in behaving non-human primates, and c) to produce interventions (e.g., deep brain stimulation or local / systemic drug delivery) that allow rescuing the generated disease phenotypes.

In trance, brain networks displayed notable reconfigurations, including increased connectivity in regions associated with internal thought (the default mode's posterior cingulate cortex) and cognitive control (dorsal anterior cingulate cortex and insula), as well as decreased connectivity within the brainstem and auditory pathway.

Now Keilholz and her colleagues have shown for the first time that dynamic functional connectivity data is â $ œgroundedâ $, because it is linked with changes in electrical signals within the brain.

These 2 modalities were used to investigate connectivity within the default mode network, a set of brain regions — including medial prefrontal cortex (MPFC), medial temporal lobes (MTLs), and posterior cingulate cortex (PCC) / retropslenial cortex (RSC)-- implicated in episodic memory processing.

Boldrini and colleagues think that the deterioration of the brain in old age could be attributed to this smaller pool or neural stem cells, reduced connectivity among cells within the hippocampus and decline in blood vessels.

Decreased functional connectivity (FC) within temporal cortex was... identified for MCIs at baseline, which was partially determined by the GRS; moreover, compensations may occur within the frontal - parietal brain to maintain relatively intact cognition.

Modularity describes specialized processing within dedicated brain regions, whereas connectivity relates to contemporaneous information flow across large - scale distributed networks.

It is also associated with greater connectivity within the brain.

One final example is the prefrontal cortex, which is thought to play an important role in regulating behavior by suppressing impulses and emotions arising from the amygdala and other parts of the limbic system.50 — 52 In animal studies, exposure to chronic stress or glucocorticoids alters the synaptic connectivity within the prefrontal cortex, 52,53 and this may limit the ability of the prefrontal cortex to (1) suppress the impulsivity and aggression of the limbic system, and (2) execute adaptive responses (rather than maladaptive responses) to stress.54 — 56 Stress - induced changes in brain structure parallel the well - described impact of significant childhood adversity on a variety of brain functions, including the modulation of physiologic responses (hyper - responsive or chronically active stress response), learning (impaired memory), and the regulation of behavior (the ability to execute adaptive vs maladaptive responses to stress).3, 39,57

Functional connectivity of the anterior cingulate cortex within the human frontal lobe: A brain - mapping meta - analysis
