    In recent years, more andmore emphasis has been placed on the investigation of sex differences in the human
    brain. Noninvasive neuroimaging techniques represent an essential tool in the effort to better understand the
    effects of sex on both brain structure and function. In this review, we provide a comprehensive summary of
    the findings that were collected in human neuroimaging studies in vivo thus far: we explore sexual
    dimorphismin the human brain at the level of (1) brain structure, in both gray andwhitematter, observed by
    voxel-based morphometry (VBM) and diffusion tensor imaging (DTI), respectively; (2) baseline neural
    activity, studied using resting-state functional magnetic resonance imaging (rs-fMRI) and positron emission
    tomography (PET); (3) neurochemistry, visualized by means of neuroreceptor ligand PET; and (4) taskrelated
    neural activation, investigated using fMRI. Functional MRI findings from the literature are
    complemented by our own meta-analysis of fMRI studies on sex-specific differences in human emotional
    processing. Specifically, we used activation likelihood estimation (ALE) to provide a quantitative approach to
    mapping the consistency of neural networks involved in emotional processing across studies. The presented
    evidence for sex-specific differences in neural structure and function highlights the importance of modeling
    sex as a contributing factor in the analysis of brain-related data.
