fMRI Study of Voice Gender Perception in Gender Dysphoria

FMRI data from a study of voice gender perception, involving 32 male-to-female gender dysphoric individuals, 20 non-dysphoric men, and 19 non-dysphoric women. Participants categorized 240 voice stimuli modified in semitone steps. The study investigated neural correlates in brain regions like the medial prefrontal gyrus and insula.

Use Cases

• Analyze fMRI activation patterns in the medial prefrontal gyrus and insula in response to male vs. female voice stimuli across participant groups.
• Correlate behavioral responses to 240 semitone-modified voice stimuli with participant group classification (MtF, men, women).
• Compare neural recruitment in prefrontal areas among men, women, and MtFs as voice morphing increases.
• Investigate the similarity of neural response patterns between MtF individuals and non-dysphoric women during voice gender perception tasks.

Strengths

• Includes data from 71 total participants, providing a multi-group comparison.
• Uses 240 distinct voice stimuli systematically modified in semitone steps, allowing for graded perceptual analysis.
• Focuses on biologically relevant voice gender perception within the context of gender dysphoria research.

Limitations

• Sample sizes per group are modest (32, 20, 19), limiting statistical power for some subgroup analyses.
• The dataset's scope is specific to a controlled fMRI experiment, which may not generalize to everyday perception contexts.
• Specific data structure, column details, and file formats are unknown, complicating immediate usability.
