The Mouse Brain in Stereotaxic Coordinates (Paxinos and Franklin) and the Rat Brain in Stereotaxic Coordinates (Paxinos and Watson) both have labelled diagrams and plates of sagittal sections.

Interpreting sagittal sections is not always easy but with some practise and using parallel series with appropriate histochemical markers of milestone nuclei you can surely orient yourself.

Only the bravest neuroanatomists dare to use sagittal or horizontal sections, but they are the good ones. Good luck.

The most known brain rats atlas contain also sagittal sections. As said by Fernando, you have to be very familiar with anatomy (neuroanatomy) and spatial disposition of nuclei and aresa (notably those of interest) to worh with them. In general, we use this plans of sections to dectect fastly if we have a labelling in sommes structures before working on coronal sections. Sagittal sections are also useful for tracing methods.

Thank you fernando and fatiha, i was exactly looking for tracing expts

the lesion method that i work involves a great deal of white matter damage

There are also mi based rat atlases from G A Johnson's group at Duke.
