V2 and V4 contain orthogonal maps of orientation and spatial frequency, which indicates a fundamental principle of functional mapping across the cortical surface that ensures and optimizes the complete representation of all combinations across two coding dimensions.

Primate attention is not limited to a dorsal fronto-parietal network, but includes a ventral temporal node and its dorso-ventral interactions with other attentional areas.

Macaque monkeys temporally compress past experiences and use a forward-replay mechanism during judgment of temporal-order between episodes.

Using novel approach to study real-time social interactions shows that mutual action visibility facilitates static and dynamic coordination in both species, but whereas humans employ dynamic turn-taking to equalize rewards, macaques, after training with a human, compete between themselves.

The macaque monkey intraparietal sulcus encompasses 17 cyto- and receptorarchitectonically distinct areas, which can be grouped into three clusters based on (dis)similarities of their molecular structure.

Whether central vestibular neurons implement faithful stimulus encoding for the vestibulo-occular reflex or optimized coding via temporal whitening for other vestibular functions is determined by neural variability.

Area V2 in macaque monkeys contributes to the perception of the outlines of moving objects and achieves this through a local computation.

A novel naturalistic environment with a touchscreen enables high-quality eye tracking for studying visual cognition in monkeys, and allows naive monkeys to learn complex tasks through a combination of social observation of trained monkeys and trial-and-error learning.

The novel Reach Cage allows neurophysiology studies of structured behavior with unrestrained Rhesus macaques showing that the frontoparietal reach network is selective for reach goals outside the immediately reachable space.

Even when the primary visual cortical area is absent bilaterally from early life, the rest of a primate visual brain can develop and function normally to support day-to-day visual behaviour.
