Sentences with phrase «related neural activity»

The fMRI results provided evidence that cognitive training improved speed - related neural activity.

A study by researchers from McGill University in Canada involving neuroimaging, which creates pictures of the brain's structure and neural activity, showed that smelling the body odor of someone closely related activates the dorsomedial prefrontal cortex, a part of the brain responsible for recognizing family.

Again, Nrf2 - related activity was observed only when astrocytes were present in cultures, but significantly, Nrf2 signaling increased in tandem with neuronal firing, suggesting that neurons calibrate Nrf2 activity in astrocytes to keep pace with neural activity.

The researchers were able to zero in on the Broca's area as well as related brain circuitry specifically linked to speech, using regional cerebral blood flow as a measure of brain activity, since blood flow is typically coupled with neural activity.

PET, fMRI and NIRSI can measure localized changes in cerebral blood flow related to neural activity.

Functional MRI produces maps of the brain based on oxygenated blood flow related to neural activity.

But neural activity in regions associated with the self and with social considerations serves as a type of common denominator for various types of social and self - related thinking.

The demonstration in this paper, that the secondary fMRI response (the post-stimulus undershoot) is not simply a passive blood flow response, but is directly related to synchronous neural activity, as measured with EEG, heralds an exciting new chapter in our understanding of the workings of the human mind.»

Furthermore, we asked what kind of sensory information induces the pattern of neural activity observed during defensive bee ball formation and found that it may relate to the processing of thermal information.

Despite decades of work, neuroscientists still struggle to describe how neural activity in the brain relates to the movements being generated.

The rats all developed two separate fears, one for each tone, which showed up in brain scans as increased neural activity in the amygdala, a part of the brain directly related to fear.

It is not known, however, how neural activity relates to eye movement measures during the viewing of naturalistic, dynamic stimuli.

Recent estimates suggest that as many as 1.9 million children younger than 18 years have a sport - or recreation - related concussion each year in the United States.1 This injury is biomechanically induced, with symptoms resulting from neuronal dysfunction due to functional and neurometabolic alterations rather than gross structural abnormalities.2 Compared with boys involved in similar activities, girls experience higher rates of sport - related concussion,3 - 7 report more severe symptoms,8 - 11 demonstrate worse cognitive impairment,8 - 10, 12 and take longer to recover.11 The neural mechanisms behind these postconcussion sex differences are poorly understood but have been attributed to differences in neuroanatomy and physiology, 13 cerebral blood flow, 14 and the female sex hormones estrogen and progesterone.15 - 17

Behavioural studies have demonstrated that viewing patterns differ measurably between static and dynamic images, so it is important to determine how neural activity relates to eye movements in more naturalistic settings.

If true, strangers should have their greatest regulatory impact on neural systems supporting the body's mobilization for acute activity, with minimal impact on processes related to vigilance or self - regulation.

Future research in cultural neuroscience (Chiao in press) may investigate the extent to which cultural values of individualism — collectivism are associated with neural response within brain regions regulated by serotonergic neurotransmission, and if so, the process by which these activity within neural pathways supports the storage and transmission of cultural values and related behaviours.

Although children who have been maltreated show different brain activity in response to facial emotion than nonmaltreated children, 22 we know little about children's neural processing of a wide variety of parenting behaviours, and we know even less about temperament - related differences in such neural processing.
