Within a few days this lip becomes applied to, and unites with, the outer surface of the main part of the alar lamina, and so covers in the tractus solitarius and also the spinal root of the trigeminal nerve; the nodulus and flocculus of the cerebellum are developed from the rhombic lip.
Neuroblasts accumulate in the mantle layer; those in the basal lamina correspond with the cells in the anterior gray column of the medulla spinalis, and, like them, give origin to motor nerve fibers; in the medulla oblongata they are, however, arranged in groups or nuclei, instead of forming a continuous column.
They bear a definite relationship to certain of the cranial nerves; thus, from before backward the first and second grooves overlie the nucleus of the trigeminal; the third, the nucleus of the facial; the fourth, that of the abducent; the fifth, that of the glossopharyngeal; and the sixth, that of the vagus.

These fibers terminate in the amygdala, hypothalamus, and ventral posterior medial nucleus of the thalamus, which then projects to the somatosensory cortex within the brain.
Thus, a lesion of the rostral nucleus solitarius, tractus solitarius, or solitariothalamic tract results in loss of taste from the ipsilesional, the same side as the lesion, half of the tongue.
As a general rule, taste is a holistic assessment of the interaction of the fundamental taste systems of sweetness, sour, bitter, salty, and umami, or "savouriness".
