Researchers specifically analyzed how different areas of the brain activate in sync with each other — a property called functional connectivity — during a period of rest.

Using two data sets of functional MRI brain scans from more than 350 adult and child siblings during resting state, Fair and colleagues applied an innovative technique to characterize functional connectivity and machine learning to successfully identify siblings based on their connectotype.

The researchers were attempting to look at the brain's so - called «functional connectivity,» that is, interactions between brain regions during the course of a particular task, or at rest, Laird said.

In this study, the researchers aimed to investigate task related brain activity and functional connectivity patterns following onset of a regional anesthetic nerve block during continuous noxious dental stimulation.

«Once we unravel the different working patterns and circuits in the brain during memory formation and decision - making, we can begin to look for differences in connectivity patterns that underlie abnormalities,» Harvey said.

They also found that the disruption of the connectivity of these cells during brain development causes alterations in brain oscillatory activity and disturbs the function of place cells, a type of pyramidal neuron that becomes active when an animal is located in a particular place in its environment.

Our data reflects the level of efficient organization of the functional brain network during a resting state and not the efficiency of functional connectivity between brain regions during the performance of specific cognitive tasks that enter into the IQ score.

Dr. Elias and the OCAR primarily focus on understanding why ERP works (e.g., fear tolerance versus fear habituation; the roles of guilt, willingness, and acceptance; patterns of brain activation during exposure; functional connectivity among brain regions), tailoring treatment to the individual (e.g., elucidation of predictors of response and their underlying processes / mechanisms and neural correlates; rigorous diagnostic characterization of obsessive compulsive related disorders), and evaluating innovative treatments and augmentation strategies (e.g., acceptance and commitment therapy; optimization of inhibitory learning; pharmacological augmentation).

Task - based functional connectivity measures the synchronization of activation levels between brain regions during the performance of a given cognitive task.

Previous studies of resting state functional connectivity have demonstrated that the default - mode network (DMN) is negatively correlated with a set of brain regions commonly activated during goal - directed tasks.

Resting - state functional magnetic resonance imaging allows investigating whole - brain connectivity changes during pharmacological modulation of the level of consciousness.Low - frequency spontaneous blood oxygen level - dependent fluctuations were measured in 19 healthy volunteers during wakefulness, mild sedation, deep sedation with clinical unconsciousness, and subsequent recovery of consciousness.Propofol - induced decrease in consciousness linearly correlates with decreased corticocortical and thalamocortical connectivity in frontoparietal networks (i.e., default - and executive - control networks).

«In general, the additional brain size and connectivity of the human brain compared to the chimpanzee or macaque, along with the protracted period of time during which human neurodevelopment occurs, means that there are many more problems than can arise and a greater period of time during which those problems can occur,» Sestan explained.

â $ œOur findings fit into an emerging theme in neuroscience research: that during childhood, there is a switch in amygdala function and connectivity with other brain regions, particularly the prefrontal cortex, â $ says Mar Sanchez, PhD, neuroscience researcher at Yerkes and associate professor of psychiatry and behavioral sciences at Emory University School of Medicine.

During the resting brain scan, the treatment group also showed greater connectivity between a region known as the «periaqueductal grey» and areas of the prefrontal cortex associated with cognition.

And studies using functional MRI measures have shown that the amount of cortical brain area used is greater during eccentric contractions than in concentric contractions (Yao et al. 2014), while functional connectivity between the primary motor cortex and other parts of the brain is reduced (Yao et al. 2016).

This week, I'm covering «Associations Between SSRI Exposure During Pregnancy and MRI - Assessed Brain Structure and Connectivity in Infants»:

Childhood Maltreatment Is Associated With Altered Fear Circuitry and Increased Internalizing Symptoms by Late Adolescence (PDF - 686 KB) Herringa, Birn, Ruttle, Burghy, Stodola, Davidson, & Essex (2013) Proceedings of the National Academy of Sciences of the United States of America, 110 (47) Examines the associations between experiences of maltreatment during childhood and functional brain connectivity in 64 adolescents participating in a longitudinal community study.
