Strangely, Wernicke's & Broca's areas tend to only exist unilaterally (on one side of the brain). In most people, they tend to both be found on the right side of the brain.

In terms of the visual pathway, after the optic nerves cross at the optic ( chiasm, nucleus, radiation ) they become optic tracts. These optic tracts move up into the Thalamus where they synapse with optic radiations at the ( lateral geniculate, medial geniculate, lentiform, solitary ) nuclei, which then radiate towards and into the primary visual cortex.
