Exploration of the brain from its basal aspect
Inferior occipitofrontal fasciculus, limen insulae and arteries of choroid plexus
More tissue of the temporal lobe and hippocampus has been removed. The relation of the inferior occipitofrontal fasciculus to both the insula and the inferior horn of the lateral ventricle is demonstrated. The uncinate bundle is cut off as it courses deep to the limen insulae. The anterior choroidal artery is seen as it penetrates the choroid plexus of the inferior horn of the lateral ventricle. The choroidal branch of the posterior cerebral artery is visible as its passes across the inferior surface of the lateral geniculate body.
