Associated disorder?
Visual perception
Partial or total loss of vision of the contralateral visual fields for both eyes, depending upon the extent of the lesion in the visual cortex
What is the general function of the ventricles?
Associated disorder?
Flow of CSF throughout the CNS: a source of electrolytes and conduit for neuroactive and metabolic products
