abstract Motion estimation is an essential ability for sighted animals to survive in their natural
environment. Many anatomical and electrophysiological studies on low visual levels have …

Interaction with the environment requires fast and reliable sensory processing. The visual
system is confronted with a continuous flow of high-dimensional input (eg orientation, color …

Periodically flipping the contrast of a moving pattern causes a reversal of the perceived
direction of motion. This direction reversal, known as reverse-phi motion, has been generally …

Motion perception is an essential ability for animals and artificially intelligent systems
interacting effectively, safely with surrounding objects and environments. Biological visual …

In an attempt to fulfil our first objective in this thesis (“2.1. Objective 1: Effect of spatial
frequency and contrast on the motion interaction mechanism”, in the “2. Objectives” section) …

When an annulus in fast apparent motion reverses its contrast over time, the foveal and
peripheral percepts are strikingly different. In central vision, the annulus appears to follow …

The perception of motion is the consequence of computations in the motion pathway in the
visual cortex. At least some of the areas that constitute this pathway depend on adequate …

Viewing static pictures of running humans evokes neural activity in the dorsal motion-
sensitive cortex. To establish whether this response arises from direction-selective neurons …

In the motion aftereffect (MAE), adapting to a moving stimulus causes a subsequently
presented stationary stimulus to appear to move in the opposite direction. Recently, the …

Classic psychophysical studies have shown that increasing the size of low-contrast moving
stimuli increases their discriminability, indicating spatial summation mechanisms. More …
