Abstract

In the marmoset Callithrix jacchus, ocular dominance columns (ODC) have been reported to be present in young animals, but absent in adults (Spatz, 1989). We have studied in juvenile and adult animals the postnatal organization of the retino-geniculo-cortical afferents by means of transneuronal labeling. We show in the present work that ODC are present in the primary visual cortex of Callithrix jacchus, both in the adult and in the juvenile animal. The present work confirms the presence of ODC in the visual cortex of juvenile marmoset before the end of the first postnatal month. In 2-month-oldanimals, ODC are well demarcated in IVc alpha and IVc beta. In the adult marmosets, the present data clearly show that the primary visual cortex is also organized with CDC. In horizontal sections, they form a mosaic through the ventral and dorsal calcarine cortex and through the dorso-lateral occipital part of the striate cortex. In frontal sections, their presence is manifest in IVc beta within the calcarine cortex and they only faintly appear in IVc alpha. These new findings are important since they underline the usefulness of the adult New World Monkeys as a model in visual research.
