Sexual differentiation of motivation: a novel mechanism?

Open access

Abstract

Sex differences in motivation are apparent for the motivation to engage in sexual behavior, the motivation to take drugs of abuse, and the motivation to engage in parental behavior. In both males and females there is an increase in NAcc DA associated with motivated behaviors. Here it proposed that sex differences in the regulation of DA activity in the ascending mesolimbic projections may underlie sex differences in motivation. In particular, sex differences in the neuroendocrine regulation of this brain system play a role in the expression of sex differences in motivated behaviors. Here it is proposed that sexual differentiation of motivation is mediated, at least in part, by a novel mechanism in which ovarian hormones secreted at puberty in the female actively feminize the DA system.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Several rodent studies point to effects of pubertal estradiol and testosterone on dopaminergic function.

    “several rodent studies point to effects of pubertal estradiol and testosterone on dopaminergic function (reviewed in Becker, 2009; Kuhn et al., 2010; Sinclair et al., 2014).”
  • Literature on the effects of pubertal hormones on the development of the dopamine system suggests that some aspects of dopaminergic function respond to pubertal increases in circulating gonadal hormones.

    “Thus, although scant, literature on the effects of pubertal hormones on the development of the dopamine system suggests that some aspects of dopaminergic function respond to pubertal increases in circulating gonadal hormones.”

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.
