Minireview: sex differences in adult and developing brains: compensation, compensation, compensation

De Vries, Geert J.·2004·Endocrinology

Abstract

Despite decades of research, we do not know the functional significance of most sex differences in the brain. We are heavily invested in the idea that sex differences in brain structure cause sex differences in behavior. We rarely consider the possibility that sex differences in brain structure may also prevent sex differences in overt functions and behavior, by compensating for sex differences in physiological conditions, e.g. gonadal hormone levels that may generate undesirable sex differences if left unchecked. Such a dual function for sex differences is unlikely to be restricted to adult brains. This review will entertain the possibility that transient sex differences in gene expression in developing brains may cause permanent differences in brain structure but prevent them as well, by compensating for potentially differentiating effects of sex differences in gonadal hormone levels and sex chromosomal gene expression. Consistent application of this dual-function hypothesis will make the search for the functional significance of sex differences more productive.

  • Understanding the underlying mechanisms that direct social development, particularly those that differ between males and females, may explain sex differences in vulnerability to neurodevelopmental disorders.

    “Understanding the underlying mechanisms that direct social development, particularly those mechanisms that differ between males and females, may explain sex differences in vulnerability to neurodevelopmental disorders (De Vries, 2004).”

    From Sexually dimorphic role for vasopressin in the development of social play (2014) · cites this paper as De Vries, 2004

    The Dual-Function Hypothesis for Neural Sex Differences (p. 2) says the mechanisms underlying social behavior may differ between males and females. The discussion of developing brains (pp. 3–4) addresses sex differences in neural development, but our copy does not link those mechanisms to sex differences in vulnerability to neurodevelopmental disorders. (LLM, conf=0.84)

  • The compensation theory postulates that some sex differences in the brain may serve to prevent sex differences in behavior allowing males and females to display similar behaviors despite major sex differences.

    “This theory postulates that some sex differences in the brain may serve to prevent sex differences in behavior allowing males and females to display similar behaviors despite major sex”
  • The finding that making sexes more alike induces a sex difference in social play is in line with the compensation theory of sex differences.

    “Although perhaps a surprising finding, it is in line with the compensation theory of sex differences proposed by De Vries and colleagues (De Vries & Boyle, 1998;De Vries, 2004).”
  • Compensatory mechanisms to reduce overt sex differences in some behaviors have been proposed previously.

    “Compensatory mechanisms to reduce overt sex differences in some behaviors have been proposed previously (40,41), and it is possible that NCoR may be a molecule involved in reducing some sex differences in social play behavior.”
  • Sex differences in VP could have a dual function: contributing to sex differences in some behaviors while preventing sex differences in others.

    “It has been proposed that these consistent sex differences in VP could have a dual function, namely contributing to sex differences in some behaviors while preventing sex differences in other behaviors”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
