Imaging studies have shown that when autistic children see a familiar face, their pattern of brain activation is different from that of normal children.

The connectivity was measured in 15 patients with visual hallucinations, 40 patients without visual hallucinations, and 15 healthy controls by calculating the level of synchronization between activation patterns of different brain areas.

Obese adolescent girls, Stice found, showed greater activation compared with their lean peers in regions of the brain that encode the sensory experience of eating food — the so - called gustatory cortex and the somatosensory regions, archipelagoes of neurons that reach across different structures in the brain.

But her most important achievement, she thinks, was shedding new light on the physiology of brain activation by using a variety of different contrast agents.

The brain regions they used to make those choices were also different: for individuals with anorexia nervosa, choices about what to eat were associated with activation in the dorsal striatum, a brain region known to be related to habitual control of actions.

Dr. Britt obtained these results using optogenetics, which use light - responsive proteins to study the activation of neural circuits in distinct locations, allowing the researcher to precisely dissect the roles of different neural circuits in the brain.

Children with the lowest scores on the social cognition tests showed atypical responses to the unknown words — no response at all, for example, or activity in a different part of the brain, while those with the higher scores showed a more typical pattern of brain activation in the left hemisphere, the authors report online today in PLOS ONE.

A second finding involved brain synchronization — a measure of how well coordinated the brain activation was across different regions of the brain.

The activation of this signaling pathway progressively increased in different types of gliomas, with the highest activity seen in patients with glioblastoma, a particularly difficult - to - treat form of brain cancer that represents approximately 15 percent of all brain tumors.

By looking at activation of different brain regions while test subjects were exposed to different listening conditions, Dr. Johnsrude's research has revealed that the early processing of sound, which occurs in a brain region called the primary auditory cortex, depends on higher - level linguistic knowledge encoded in other regions of the brain.

In different experiments we will examine the effects of exogenous (intranasal oxytocin) and endogenous (providing social support) oxytocin on fear and reward related brain activation patterns, functional connectivity, stress reactivity and trauma - related psychopathology symptoms.

The stimulation of different acupoints in the same spinal segment could induce different fMRI activation patterns in the brain [142] while acupoints on the same meridian show some similarities in the activation / deactivation pattern [23].

Magnesium is one of the most important mineral because it is needed for over 350 different processes in your body; among these functions are digestion, energy production, bone formation, energy production, muscle function, creation of new cells, activation of B vitamins, relaxation of muscles and the functioning of your brain, heart, kidneys, along with your nervous system.

Assumptions are often made that differences in patterns of brain activation between females and males in a particular task must mean that females and males use different mental processes to complete that task; however, mental processes are highly complex and involve interaction between many different regions of the brain (Fine, 2013).

Different responses exhibit different patterns of brain actDifferent responses exhibit different patterns of brain actdifferent patterns of brain activation.)

Our results are in line with other neuroimaging studies that have found reduced activations to different kinds of affective stimuli within the brain emotional systems in violent adult subjects and in adolescents with conduct disorder.
