Functional specificity in lateral frontal cortex for the 12-component estimate. A functional specificity value of 2 at a vertex implies that for an activated vertex, the top component would be twice as likely as the second most likely component to be recruited. Therefore, a functional specificity of 2 suggests at least some degree of functional specialization. Only regions with statistically significant (corrected for multiple comparison for entire cerebral cortex, FDR q < 0.05) functional specificity of at least 2 are shown. The somato-motor cortex exhibited higher functional specificity than the lateral frontal cortex. Nevertheless, 7 components exhibited significant specificity, demonstrating functional segregation in lateral frontal cortex. Note that the color scale is logarithmic.
