The Brodmann areas in Conte-69 space are derived from a cortical surface, converted using Caret software to a volume by assuming a uniform cortical thickness. The data is available at SumsDB.
The segmentation uses the T1w/T2w ratio as an indicator for Myelin content. The criteria and the Conte 69 data are described in:
Matthew F. Glasser and David C. Van Essen (2011) "Mapping Human Cortical Areas in vivo Based on Myelin Content as Revealed by T1- and T2-weighted MRI" J Neurosci. 31(32):11597–11616. 10.1523/JNEUROSCI.2180-11.2011.
The Conte-69 space is composed of 69 control subjects (37 males, 32 females, age mean 22 +/− 6) from the Conte Center. Subjects were scanned at Washington University in St. Louis and at Northwestern University on Siemens 3T Tim Trios using a 12-channel head coil. A 3D T1w Magnetization Prepared RApid Gradient Echo (MPRAGE: TR=2400ms, TE=3.16ms, TI=1000ms, 8° flip angle, bandwidth=220 Hz/Pixel, echo spacing=7.5ms, FOV 256mm × 256mm × 176mm, matrix 256 × 256 × 176, 1mm isotropic resolution) sequence was acquired.
