As arboreal primates move through the jungle, they are immersed in visual motion that they
must distinguish from the movement of predators and prey. We recorded dorsal medial …

When a moving object cuts in front of a moving observer at a 90° angle, the observer
correctly perceives that the object is traveling along a perpendicular path just as if viewing …

Human heading perception based on optic flow is not only accurate, it is also remarkably
robust and stable. These qualities are especially apparent when observers move through …

Humans accurately judge their direction of heading when translating in a rigid environment,
unless independently moving objects (IMOs) cross the observer's focus of expansion (FoE) …

Recent findings of vestibular responses in part of the visual cortex—the dorsal medial
superior temporal area (MSTd)—indicate that vestibular signals might contribute to cortical …

When we move around in the environment, we continually change direction. Much work has
examined how the brain extracts instantaneous direction of heading from optic flow but how …

Many forms of locomotion rely on the ability to accurately perceive one's direction of
locomotion (ie, heading) based on optic flow. Although accurate in rigid environments …

Accurate heading perception relies on visual information integrated across a wide field, that
is, optic flow. Numerous computational studies have speculated how local visual information …

Steering demands rapid responses to heading deviations and uses optic flow to redirect self-
movement toward the intended destination. We trained monkeys in a naturalistic steering …

Self-motion, steering, and obstacle avoidance during navigation in the real world require
humans to travel along curved paths. Many perceptual models have been proposed that …
