 Quantifying Neuroanatomic Differences

This chapter provides a description of neuroanatomical differences, with an emphasis on quantification. An overview of methods used to measure brain structures along with basic rules for the manual parcellation of brain components is given. Calculations of gray and white matter composition for different brain regions are provided, and differences between hemispheres as well as differences related to gender, aging, and congenital deafness are addressed. Images depicting twenty-three female and twenty-three male brains are paired in descending order of total volume. The lobes are color-coded and volumes for gray and white matter are provided for each brain, as is age at the time of scanning.

Keywords: brain parcellation; gray matter; white matter; brain differences; gender; aging; congenital deafness
