A B'omarr monk's brain, preserved in a jar.
The brain functioned as the primary center for both thought and awareness within living beings. Certain species, for instance the Cereans and Siniteen, possessed brains of a larger size than most.

The B'omarr Order practiced the removal of their members' brains, storing them within specialized jars filled with nourishing fluids. These containers could then be connected to spider-like droid walkers, which afforded the monk mobility.
