Sentences with phrase «between brain circuitry»

«It is exciting to find a correlation between brain circuitry and gene expression by combining high quality data from these two large - scale projects,» says David Van Essen, Ph.D., professor at Washington University in St. Louis and a leader of the Human Connectome Project.

Not exact matches

It's because the distance between synapses carrying similar messages — positive or negative — shortens to make it easier for information to be shared via brain circuitry.

Her research is part of growing evidence that has yielded an entirely new understanding of molecular differences reflected in the brain between men and women, and how outside forces can permanently imprint neurological circuitry in sex - based ways.

Somehow the rules governing synaptic connections between cells enable such «local» activity to modify the «global» neural circuitry that carries out the brain's many functions.

The researchers studied how active the reward circuitry of their brains was when anticipating and receiving money to learn whether there were differences between the two groups in the key brain regions.

Now, researchers have developed the first diagram of the brain circuitry that enables this complex interplay between the motor system and the auditory system to occur.

Based on previous studies, researchers have hypothesized that recreational noise exposure might damage the circuitry between sensory hair cells in the inner ear and their auditory nerve targets that deliver information to the brain.

Once thought of as mere packing peanuts whose job it was to keep neurons from jiggling when we jog, astrocytes are now understood to provide critical hands - on support and guidance to neurons, enhancing their survival and shaping the shared connections between them that define the brain's labyrinthine circuitry.

Unfortunately, he says, the fMRIs failed to reveal the inhibitory circuitry involved; to try to get to the bottom of that, he plans to repeat the study using electroencephalography (EEG), which involves placing many electrodes on a skintight rubber cap placed over a subject's head that allows researchers to observe communication between different parts of the brain.

While many aspects of brain circuitry are hard - wired, it is also dynamic: the connections between neurons in the brain change with experience to store information, and in this way nature and nurture combine to define our identities.

It may simply be that effects like this aren't the result of direct selection, but are just byproducts of the fact that the brain uses the same circuitry to respond to different stimuli, so there can be unintended cross-talk between inputs.

Larry Young, a professor of psychiatry at Emory University who studies the neurological basis of complex social behaviors, thinks human evolution has harnessed an ancient neural circuit that originally evolved to strengthen the mother - infant bond during breastfeeding, and now uses this brain circuitry to strengthen the bond between couples as well.

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.

This is particularly true during the period of adolescence when the brain undergoes a substantial remodeling of its neural circuitry to increase the linkages between the prefrontal cortex (important in self - control) and the brain's limbic system (important in processing of emotional information).
