Joy Williamson asked if the corpus callosum was larger in women than in
men. Well yes it is when *adjusted* for forebrain volume and here is the
reference you required.
Steinmetz H; Staiger JF; Schlaug G; Huang Y; Jancke L.
Corpus callosum and brain volume in women and men.
Neuroreport, 1995 May 9, 6(7):1002-4.
Abstract: Using high-resolution in vivo magnetic resonance morphometry we
measured the midsagittal area of the corpus callosum and total
forebrain volume in 120 healthy young adults (mean age (+/- s.d.) 25.7 +/-
4.7 years). The forebrain volume-adjusted size of the corpus callosum was
larger in women than in men (32 mm2 mean difference; p = 0.011).
Handedness had no effect in this measurement. The morphometric data
confirm a gender difference in cerebral structural organization.
