Beschreibung / Abstract
The perception of motion is probably one of the major challenges to our sensory system.
Motion perception is crucial during the tracking of moving objects (prey, predator etc.)
and to maintain spatial orientation during locomotion. Moreover, it is typically a
multisensory event. In everyday situations, the visual sense is supposed to provide the
most accurate information since its spatial resolution is the most accurate among the
senses. However, auditory and somatosensory supplements are aligned to vision and help
to generate a more accurate percept of a given situation. Visual motion has been
investigated intensively for many years. Compared to vision, auditory and tactile motion
perceptions are far less understood. Today, it is still not understood if motion perception
is a common feature, following the same principles among the senses and maybe
processed within the same brain regions.
