Bellani M, Brambilla P. The striatum and nucleus accumbens play a critical role in brain reward circuitry implicated in the craving properties of drugs of abuse [ 73 ]. Sign In. Hypotheses : Female adolescents with severe substance and conduct problems will show significantly less gray matter volume in frontal regions critical to inhibition i.
Previous studies on sex differences in neural responses to noxious stimuli yielded mixed results.
Power failure: why small sample size undermines the reliability of neuroscience. An additional hypothesis—one that is not incompatible with the hypothesis that some of the sex differences seen here are a proximate cause of behavioral differences—is that brain structural differences might sometimes be the result of compensatory mechanisms for differences in sex-specific brain sex differences orbitofrontal cortex and depression in Eydzhaks, and might thus act to reduce behavioral sex differences that would otherwise have been present De Vries ; McCarthy and Arnold To illustrate this point, in the most recent meta-analysis of macrostructural sex differences in brain subregions Ruigrok et al.
Erickson began to suspect that her sexual feelings were emanating not from her ovaries but from her head. A set of Bayesian t -tests see Supplemental Materials and Table 1 confirmed that the mean sex differences were very large, with extremely strong evidence in favor of the hypothesis that males differed from females on every overall and subcortical volume.
