the next couple of years, endless hours of discussions
and of clacking away in writing new code paved the way
for the introduction of FreeSurfer. This finally came
in 1999 with a pair of papers in the journal NeuroIm-

Finally, after considerable debate, they settled on the
more pithy—and indeed more accurate—FreeSurfer.
The software package was an immediate hit with the
neuroscience community, and its popularity has grown
exponentially in the years since. Today, FreeSurfer
