SNOMED has codes for the corticobulbar and corticospinal tracts and thalamic radiations in specific regions (e.g., internal capsule), but not generic codes independent of their regional location, so they are not used.
(410726006, SCT, "auditory radiation") is also known as the acoustic raditaion, or geniculotemporal tract.
(70105001, SCT, "optic radiation") is also known as the geniculo-calcarine tract, geniculostriate pathway or posterior thalamic radiation.
