Traditionally, the dorsal lateral geniculate nucleus (LGN) and the inferior pulvinar (IPul) nucleus are considered as anatomically and functionally distinct thalamic nuclei. However, in several primate species it has also been established that the koniocellular (K) layers of LGN and parts of the IPul have a shared pattern of immunoreactivity for the calcium-binding protein calbindin. These calbindin-rich cells constitute a thalamic matrix system which is implicated in thalamocortical synchronisation.

Here we present an integrated neuro-histological pipeline as well as a grid-based tracer injection strategy for systematic mesoscale connectivity mapping in the common marmoset (). Individual brains are sectioned into ~1700 20 µm sections using the tape transfer technique, permitting high quality 3D reconstruction of a series of histochemical stains (Nissl, myelin) interleaved with tracer labeled sections.

- Research until the late 20th century suggested sensory modalities in primates were independently processed, with cross-modal integration being limited to specialized areas.
- Findings in macaques showed that the primary visual cortex (V1) has direct connections from auditory cortex, challenging this model.
- In a study with marmosets, researchers confirmed similar direct projections from auditory areas to V1, highlighting early-stage audiovisual integration as a common trait in primate sensory processing.
