Document Summary

Lecture 4 the visual sense of motion. Cerebral cortex has several regions that specialize in analyzing visual motion: most prominent = middle temporal area (mt) Important in motion: this region was first identified at the posterior end of the middle temporal gyrus in the owl monkey. In humans the equivalent area is located around the ascending limb of the inferior temporal sulcus (its: anything below it is the inferior temporal lobe. That is where the fusiform face area is, and other areas important in memorizing faces and places. Mt is part of a larger motion complex, called mt+ (figure 4. 1), which contains multiple regions, each specialized in different aspects of motion perception. direction not. With only mt+: without this region our automatic perception of motion is lost. Instead the visual motion becomes a series of stills. With mt+; can see where the cars are moving (direction) and their speeds.
