Three directional planes exist in the brain:
rostral/caudal, dorsal/ventral, and
medial/lateral. When sectioning (cutting) the brain, which planes are visible is determined by the type of section. In the sagittal section (which is made parallel to the midline, dorsal to ventral) the rostral/caudal and dorsal/ventral planes can be seen. In the coronal or cross section (made perpendicular to the midline, dorsal to ventral) the medial/lateral and dorsal/ventral planes can be seen.
There are numerous specific parts of the brain that we could name and explore. The following is a list of structures within the four basic subdivisions of the brain:
Forebrain
Telencephalon: cerebral cortex, corpora striata (caudate nucleus, internal capsule, putamen), and rhinencephalon (olfactory brain, e.g., olfactory bulb, hippocampus,
amygdala, septal region, and cingulate cortex)
Diencephalon: thalamus, hypothalamus, pineal gland, and posterior lobe of the
pituitary (a migrated portion of the hypothalamus)
Midbrain
Mesencephalon: corpora quadrigemia (tectum--inferior and superior colliculi),
tegmentum
Hindbrain
Metencephalon: cerebellum, pons
Myelencephalon: medulla oblongata
Brain Stem: pons, medulla, spinal cord.
