Blindsight is the condition in which someone with damage in the primary visual cortex reports that they cannot see an object, but can usually guess what that object is.  This means that some visual representation must reach the frontal speech area.  What non-thalamic pathway might do that?   Question 8 options:   A)  The pathway through the suprachiasmatic nucleus   B)  The dorsal visual pathway   C)  The pathway through the superior colliculus   D)  The magnocelluar or M pathway
