NCIt definition : Either side of the cerebellum separated by the vermis.;
Alternative definition : UBERON: A paired regions of the cerebellum that lie outside and lateral to the central
vermis[MP]. The cerebellum consists of three parts, a median and two lateral, which
are continuous with each other, and are substantially the same in structure. The median
portion is constricted, and is called the vermis, from its annulated appearance which
it owes to the transverse ridges and furrows upon it; the lateral expanded portions
are named the hemispheres. The lateral hemisphere is considered the portion of the
cerebellum to develop most recently. [WP,unvetted].;
