Alexia without agraphia, a callosal disconnection syndrome
		• Patients have a lesion of the left visual cortex and the splenium (most posterior part) of the corpus callosum. • Visual information cannot get to the speech area, so  the patients cannot read. • Visual information can get to the motor area, so they can write. • They can’t read what they have written. • They can’t name colors, although they can match colors.
