We describe an atlas of the C57BL/6 mouse brain based on MRI
and conventional Nissl histology. Magnetic resonance microscopy
was performed on a total of 14 specimens that were actively
stained to enhance tissue contrast. Images were acquired with
three different MR protocols yielding contrast dependent on spin
lattice relaxation (T1), spin spin relaxation (T2), and magnetic
susceptibility (T2*). Spatial resolution was 21.5 microns
(isotropic). Conventional histology (Nissl) was performed on a
limited set of these same specimens and the Nissl images were
registered (3D-to-3D) to the MR data. Probabilistic atlases for
37 structures are provided, along with average atlases. The
availability of three different MR protocols, the Nissl data,
and the labels provides a rich set of options for registration
of other atlases to the same coordinate system, thus facilitating
