Childhood to adulthood: changes in brain volume and gray mass density.

For years, common narratives in human developmental neuroimaging have been grayscale in the brain, the tissue found in the areas of the brain responsible for muscle control.
sensory perception (e.g. hearing and memory, memory, emotion, speech, decision-making and self-control) declines during puberty, mainly as a result of studies of gray mass volume and cortoria thickness (the thickness of the outer layer of the brain containing grayscale).
now that larger brain volumes have been identified as associated with better cognitive ability, it is confusing to note that cognitive performance shows dramatic improvements from childhood to adulthood, while brain volume and cortical thickness decrease. A new study published this month by
medical researchers, published in the journal Neuroscience, may help solve the problem, revealing that while volume does decrease from childhood to adulthood, gray density actually increases.
their findings also show that although women's brains are smaller and proportional to smaller volumes, they have higher gray density than men, which may explain why they perform better cognitively, albeit with lower brain volumes.
, although adolescents lose brain capacity and women lose less brain volume than men, they are compensated for by increased grayscale density.
"s single study to solve a paradox that has lingered in this field for decades is a very rare thing, let alone two paradoxes, as Gennatas is analyzing for this large amount of research data on the entire youth population.
we now have a richer, more comprehensive concept of what happens during brain development, and now we have a better understanding of complementary processes in the brain that describe what happens," he said.
study was led by Dr. Ruben Gur, professor of psychiatry, neurology and radiology at the Perelman School of Medicine at the University of Pennsylvania.
Gur, the findings may better explain the extent and intensity of changes in mental life and behavior that occur from childhood to anth form.
If we are confused about the behavior of adolescents, it may help us to know that they need to adapt to a brain that is changing its size and composition, while the demands on performance and acceptable behavior continue to grow," Gur added. In the
study, researchers evaluated 1,189 adolescents between the ages of 8 and 23 who completed magnetic resonance imaging as part of a community-based brain development study that included rich neuroimaging and cognitive data on a variety of measures of gray matter, gray matter density, and cortical thickness.
neuroimerics has led researchers to introduce several measurements of the structure of the human brain in a non-invasive manner.
these measures over the course of development could allow researchers to study brains of different ages to show the differences between children's brains and adults.
new features of brain development may help us better understand the relationship between brain structure and cognitive performance," said Geneatas, another.
" our findings also highlight several measures that need to examine brain structure at the same time, but gray mass density may be associated with understanding the importance of improving performance in brain development.
" requires further research to fully map the biological basis of different MRI-derived measurements by combining neuroimerics and brain histology.
the study's findings in healthy populations could also help researchers understand the effects of brain disease in men and women during puberty.
