Seeing biological motion
Article Abstract:
Humans are able to perceive biological motion, as was initially shown using early work from the cinema. An impression of human animation, and details on the sex of walkers can be conveyed using illuminations of walkers' joints. Observers' sensitivity to motion rises quickly according to the number of joints illuminated, and this rise is more rapid than is the case with simple motion. Mechanisms used to analyse biological movements appear to adapt according to the stimulus.

Compression of visual space before saccades
Article Abstract:
Researchers have established changes in apparent visual direction prior to the onset of a saccadic eye movement involves compression of visual space. The compression process reduces numbers of pattern elements. The suppression of the magnocellular pathway is apparent during saccadic eye movements and may be related to visual space compression. Further research is required to discover more about the process of visual compression.

Two stages of visual processing for radial and circular motion
Article Abstract:
Psychophysical evidence provides proof that there are two-stages of visual processing with the first stage limiting the second stage's contrasts. The first stage appears to be a local-translation detector while the second stage involves medial superior temporal cortex neurons that are widely receptive to circular, radial and spiral motion.
