Using stereological analysis of NeuN-stained sections, we investigated neuronal density and number of neurons per column throughout the marmoset cortex. Estimates of mean neuronal density encompassed a greater than 3-fold range, from >150 000 neurons/mm3 in the primary visual cortex to ~50 000 neurons/mm3 in the piriform complex. There was a trend for density to decrease from posterior to anterior cortex, but also local gradients, which resulted in a complex pattern; for example, in frontal, auditory, and somatosensory cortex neuronal density tended to increase towards anterior areas.

- 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.
