An MRI Study: Why Being An Only Child Affects Your Brain
MRI technology is traditionally used for creating images for patients of any areas of concern, but scans can also be used for research. Psychologists and researchers often utilize MRI technology in fMRI’s, which focus primarily on studying the brain. This new study has revealed interesting information about the brains of only children.
Changes In The Brain of Only Children
While only children are often plagued with the stigma of being more annoying and selfish, a Chinese MRI study attributes these perceived traits as being caused by changes in the structure of their brains. The study showed that the brain of an only child was more creative and less agreeable.
Differences In The Brain
MRI scans revealed extra gray matter in the supramarginal gyrus which is the part of the brain attributed to creativity. The extra time alone can also cause only children to think out of the box and more independently. The study also noted less gray matter in the medial prefrontal cortex portion of the brain that is responsible for agreeableness.
The focus group for the study had about 270 college students participate, half with siblings and the other half without any. The MRI study found a significant rise in creativity and a fall in agreeableness in the brains of those that were only children.
The Use Of fMRI Technology
MRI’s are a common tool for imagining for radiology because of the high-resolution images and good contrasts in varying tissues. fMRI’s are commonly used in brain studies because they utilize MRI technology in a way that is sensitive the brain’s anatomy. fMRI’s often focus on changes in the neural activity in certain regions of the brain.
