Level 5 - mechanism / opinion, no new human data
Narrative review and perspective paper with no new human empirical data.

What was done
The authors reviewed historical and subsequent literature on the mapping of the female somatosensory cortex, evaluating Wilder Penfield's findings from surgical patients with intractable epilepsy and later human mapping studies.
What was found
The abstract reports no numerical data. It notes that while Penfield mapped both sexes, female findings were minimally reported and standard brain maps depict male anatomy. Significant knowledge gaps persist regarding the full representation of the female body and how it may be modulated by hormones, reproductive stages, and physiological experiences.
Why it matters
Highlighting gaps in female cortical mapping helps direct future neuroimaging research and may improve the understanding and treatment of sex-specific pain syndromes, including vulvodynia, fibromyalgia, and post-surgical pain from mastectomy or hysterectomy.
Limits
This is a narrative review presenting no new empirical data, quantitative analysis, or systematic review protocol. Sample sizes and detailed parameters of cited studies are not provided in the abstract.
