This book discusses the hypothesis that the primate pulvinar
contains an original scaffold which is derived from
cytoarchitectural markers and specific protein distributions.
Thereafter, along primate evolution, different selective
pressures acted in order to shape and fine-tune the connectivity
of the pulvinar with specific regions of the neocortex. This
divergence created, among other things, the different sets of
retinotopic map representations in the pulvinar nucleus depending
on functional and behavioral requirements of each species.

The pulvinar, the largest nucleus of the primate thalamus, has
extensive and reciprocal connections with several areas of the
neocortex. These input-output loops suggest that the pulvinar may
regulate the flow of information within and between cortical
areas in a highly dynamic fashion. Therefore, understanding the
anatomical subdivisions within the pulvinar, and its connectivity
with the cortex, is paramount to understanding pulvinar
physiological function. However, there is a stark contrast
regarding the way that the pulvinar is subdivided depending on
the technique employed. Cytoarchitectural and immunohistochemical
methods reveal a very similar pattern of pulvinar subdivision
across Old- and New-World monkeys. On the other hand,
electrophysiological and connectivity studies expose clear
discrepancies in pulvinar organization across primate evolution.
