stri·ate bod·y

the caudate and lentiform (lenticular) nuclei; the striate appearance on section is caused by slender fascicles of myelinated fibers. Histologically, the striate body can be subdivided into the generally small-celled striatum, consisting of the caudate nucleus and the outer segment of the lentiform nucleus (the putamen), and a large-celled globus pallidus composed of the two segments.

This dissection, which follows the planes of the fetal and neonatal rat brain, includes the corpus striatum, hippocampal formation, and neo-cortex within the area designated "forebrain." The region designated "midbrain + brainstem" includes the midbrain, colliculi, pons, and medulla oblongata (but not cervical spinal cord), as well as the thalamus.
