TLDR
Visual receptive-field characteristics were determined for 154 cells in the ventral lateral geniculate nucleus (VLG) of cats anesthetized with nitrous oxide and found no consistent relationship between receptive- field size and visual-field eccentricity for VLG cells, in contrast to the DLG.Abstract:

Hierarchical and parallel mechanisms in the organization of visual cortex
TL;DR: It is argued that it seems fruitful to regard the retino-geniculate-cortical pathway, and perhaps the visual pathways in general, as comprising distinct neuronal channels which begin with the major groupings of ganglion cells, and subserve distinct functions within the overall operation of the visual system.

The Ventral Lateral Geniculate Nucleus and the Intergeniculate Leaflet: Interrelated Structures in the Visual and Circadian Systems
TL;DR: A comprehensive summary of research on these thalamic areas, drawing on anatomical, electrophysiological, and behavioral studies suggests that the vLGN and IGL play a major role in mediating non-photic phase shifts of circadian rhythms, largely via neuropeptide Y, but may also play a role in photic phase shifts and in photoperiodic responses.

Fine structural morphology of identified X- and Y-cells in the cat's lateral geniculate nucleus.
TL;DR: Four physiologically identified neurons in the A laminae of the cat’s dorsal lateral geniculate nucleus were filled with horseradish peroxidase and studied using the electron microscope, and major fine structural differences observed between X- and Y-cells were almost entirely related to the retinal afferents.

The Intergeniculate Leaflet Partially Mediates Effects of Light on Circadian Rhythms
TL;DR: The data support the interpretation that the IGL plays a significant role in relaying information regarding illu mination intensity to the SCN, and modify the change in period of the free-running activity rhythm produced by changing the level of constant light.
