The following is an edited excerpt.

A new 3D brain map called BigBrain is the most detailed ever constructed. The precise placement of the neurons that make up our brain circuitry has been difficult to map, largely because the human brain’s surface is covered with folds and creases.

To make the new map, scientists embedded a brain in wax, sliced it into more than 7400 sections each 20 micrometres thick and made digital images of the slices at a resolution of 20 micrometres.

Because the images’ resolution was so high, the computer was able to determine the 3D shape of each fold correctly, even if the slice had been cut at an angle.
