TL;DR: Different patterns of synaptic contacts made by different terminals can be found on branches of a single axon and correspond to the variations in terminal arbors described in the preceding paper.

TL;DR: The manner in which each retina can be mapped onto a single cross section of the optic tract of the cat has been defined by neuroanatomical methods and it has been found that the contralateral nasal hemi‐retina and both temporal hemi-retinae are represented by multiple, rough maps which partially overlap one another.

TL;DR: The retinal afferents to the medial interlaminar nucleus and to its rostro‐dorsal extension at the edge of the pulvinar have been studied in cats by fiber degeneration and autoradiographic methods.

TL;DR: The distribution of groups of axons suggests that they may correspond to classes of retino-geniculate axons that have been characterized elect rophysiologically, and the larger diameter axons show the same distribution as X- and Y-cell axons, while the finer axons appear to correspond to W- cell axons.

TL;DR: Ther terminal arbors of individual retinogeniculate axons that have been induced to grow into an inappropriate geniculate layer have been revealed for light and electron microscopic study by being filled with horseradish peroxidase.
