The JFRC2013
reference brain is a single female brain. It
is a spatially calibrated version of the brain used in Aso et al. 2014,
"The neuronal architecture of the mushroom body provides a logic for
associative learning".
JFRC2013.surf
was generated in Amira from a 2 micron
downsampled and median filtered version of the JFRC2013 template brain.
Further cleaning was then carried out in MeshLab to remove non-manifold
edges and fill holes.
JFRC2013DS
is a downsampled version of the
JFRC2013
reference brain, designed for use with images taken on a
microscope with 20 x magnification. The downsampling has shrunk the z
direction, such that the brain appears flattened when compared with the
original.

The isotropic calibration of 0.38 microns is based on a personal communication from Yoshi Aso on 21st May 2014, where he noted:
It is 0.38um isotropic. Due to dehydration steps with EtOH, tissues are about 20% smaller than when mounted in Vectashield or other glycerol based mounting medium.
No attempt was made to correct for this shrinkage artefact.
