10 Questions
What area of the brain processes motion aftereffects?
V5
What is motion aftereffect?
An illusion experienced after viewing a moving stimulus and fixating on a stationary object
Where are cells that respond preferentially to object motion in a particular direction found?
V1
What is interocular transfer related to in visual motion perception?
Transfer of motion aftereffects to the other eye
In induced motion, why does a stationary or moving object appear to move differently?
As a result of other moving objects nearby in the visual field
What is the purpose of cell D in the Reichardt model of motion detection?
To delay input from neuron 1 for a brief time
In the Reichardt model, what is the role of cell X?
Multiplying input from neuron 1 by input from neuron 2
What is the key feature that allows the Reichardt model to respond only to left → right motion?
Cell D delays input from neuron 1
What type of motion does the Reichardt model perceive without observing real motion?
Apparent motion
Where does the global motion information pass through en route to V1?
Magnocellular layers of the LGN
Explore the concepts of visual motion perception, including the processing of colours, shapes, and sizes in our brains. Learn about how motion aftereffects create visual illusions after viewing moving stimuli. Understand the role of cells in V1 that respond to object motion in specific directions.
