+\description{
+The \code{JRC2018F} reference brains is an average template
+  brain constructed from brains labelled with brp-SNAP, dehydrated, and
+  mounted in DPX and imaged at 0.19 x 0.19 x 0.38 microns. The image was
+  downsampled in XY to result in a 0.38 micron isotropic voxel size, which we
+  take to be the standard JRC2018F space.
+
+The \code{JRC2018U} reference brain was constructed as for
+  \code{JRC2018F} brain but pooling both male and female brains.
+
+\code{JRC2018F.surf} and \code{JRC2018U.surf} were generated in
+  Amira from a 2 micron downsampled and Lanczos filtered version of the
+  JRC2018F template brain. A surface was then generated with a threshold
+  level of 20; this was then smoothed and downsampled. See
+  \code{data-raw/JFRC2018_FEMALE_surface.hx} or
+  \code{data-raw/JRC2018_UNISEX_surface.hx} for details.
+}
+\details{
+For the central brain, Bogovic and Saalfeld used 36 female
+  individuals (72 images including left-right flips) for the female template,
+  26 male individuals (52 image with left-right flips) for the male template,
+  and the union of both for the unisex brain template: 62 individuals (124
+  images with left-right flips).

-\description{
-The \code{JRC2018F} reference brain is a an average template
-  brain constructed from brains labelled with brp-SNAP, dehydrated, and
-  mounted in DPX and imaged at 0.19 x 0.19 x 0.38 microns. The image was
-  downsampled in XY to result in a 0.38 micron isotropic voxel size, which we
-  take to be the standard JRC2018F space.
