The anterior division is connected to the eyes and frontal filaments via the optic tracts, and the posterior division is connected to the antennules via the antennular nerves [ILLUSTRATION FOR FIGURE 4A OMITTED].
The presence of RAPD (also known as Marcus Gunn pupil) indicates asymmetrical retinal, optic nerve, chiasm, optic tract or mid-brain pre-tectal area damage.
Lesions in anterior part of optic tract produce incongruous visual field defects.
10) The pretectal nucleus of the optic tract, allied to the accessory optic system, provides the neural substrate for the asymmetry in laterally eyed animals (Figure 2a), in which stimulation of the nucleus of the optic tracts elicits OKN with slow phases to the side of the nucleus.
Afferent input from the retina, optic nerve, and subsequent anterior visual pathways (chiasm, optic tract and midbrain pathways)
The LGN is quite small and it is unusual for a lesion to involve the nucleus alone without encroaching on the optic tract or radiations either side of it.
