Document Summary
Selective adaptation: used to study waterfall illusion; exposing eye to a moving pattern such as a field of stripes. Reichardt detector: neuron tuned for a specific direction and speed of movement. For higher target velocities, the peripheral retina is better able to detect movement, due to the increased proportion of transient response cells. Isoluminant patterns: patterns of lines or forms that are distinguished from their backgrounds only on the basis of the hue dimension of colour; all luminance differences are eliminated. The temporal lobe contains neurons called the medial temporal area and the medial superior temporal areas. V5 is specialized for motion and speed; contains larger receptive fields. Motion coherence: the correlation between the movements of dots in successive frames. Image-retina system: responds to image changes on the retina. Eye-head system: interprets motion from eye and head movements. Subject-relative change: movement of target relative to observer"s position in space. Object-relative change: movement of target relative to other objects.
