Nervous System Physiology

In humans, lesions in the central visual pathways may have different consequences to the visual field (Fig.). A, lesions (1–5) in the central visual pathways (seen from above); B, visual field deficits (a-e, deficits shown in black, as seen by the affected person) caused by lesions in A.

Figure 1. Figure 1.

Using the information and data, determine which of the statements are true or which are false.

A. Lesion 2 corresponds to visual field deficit a
B. Lesion 3 corresponds to visual field deficit d
C. Lesion 4 corresponds to visual field deficit e
D. Lesion 5 corresponds to visual field deficit c
