Brain development sex differences in africa in Grafton

A surprise that is emerging is that it may not be specific genes per se but the number of X chromosomes that is key. Sign In. One possible corollary of this finding is that these middling-length edges could preferentially connect regions that show significant moderating effects of SES.

Hommer D.

Specifically, we predicted that i network controllability differs by sex, ii network controllability changes with age differently in males and females, iii sex differences in network controllability predict false positives on the CPT [ 37 ], and iv network controllability predicts the activation of brain regions during a working memory task demanding executive function.

Limitations Several limitations regarding the sample size of the meta-analyses and individual study parameters should be acknowledged. Shepherd A. R: a language and environment for statistical computing. First, we use a time-invariant, linear model of brain dynamics because its network control brain development sex differences in africa in Grafton have been well characterized mathematically.

Conclusion In summary, new advances in elucidating the biological foundations of sex differences in the brain shed light on the potential source of male vulnerability to neuropsychiatric and neurological disorders with origins in development. Specifically, we predicted that i network controllability differs by sex, ii network controllability changes with age differently in males and females, iii sex differences in network controllability predict false positives on the CPT [ 37 ], and iv network controllability predicts the activation of brain regions during a working memory task demanding executive function.

Age and sex effects on brain morphology. There are two means by which the number of X chromosomes can matter.

  • Michael D. De Bellis, Matcheri S.
  • Sex differences in the human brain are of interest for many reasons: for example, there are sex differences in the observed prevalence of psychiatric disorders and in some psychological traits that brain differences might help to explain.
  • Research investigating the development of these two structures has shown that differences in age, sex, and pubertal status affect the bulk volume of these brain structures. However, researchers have yet to understand the dynamics of volume and shape change that occur between childhood and early adulthood.
  • Study record managers: refer to the Data Element Definitions if submitting registration or results information.
  • Sexual differentiation of the brain is a function of various processes that prepare the organism for successful reproduction in adulthood.

Van Laere. However, when the studies were broken down into different age categories, some categories were more represented than others, depending on the compartmental volume. Bora E. It remains unknown whether and to what extent the pathophysiology of executive deficits is sex-specific.

Historical overview What seems inherently obvious today—that neuroanatomical substrates contribute to, and at times direct, sex differences in brain and behavior—was not always the case.
