| radiatio | In neuroanatomy, a term applied to any one of the thalamocortical fibre systems that together compose the corona radiata of the cerebral hemisphere's white matter (e.g., optic radiation, acoustic radiation, etc.). Synonym: radiation. Origin: L. (05 Mar 2000) |
| radiatio acustica | The fibres that pass from the medial geniculate body to the transverse temporal gyri of the cerebral cortex by way of the sublentiform part of the internal capsule. Synonym: radiatio acustica. (05 Mar 2000) |
| radiatio corporis callosi | The spreading out of the fibres of the corpus callosum in the centrum semiovale of each cerebral hemisphere. Synonym: radiatio corporis callosi. (05 Mar 2000) |
| radiatio optica | The massive, fanlike fibre system passing from the lateral geniculate body of the thalamus to the visual cortex (striate or calcarine cortex, area 17 of Brodmann); the fibres follow the retrolenticular and sublenticular limbs of the internal capsule into the corona radiata but they curve back along the lateral wall of the temporal and occipital horns of the lateral ventricle to the striate cortex on the medial surface and pole of the occipital lobe.
