Document Summary

Animal species has evolved to adapt to ecological niche in the environment so that the nervous system deals with the experience of the species. A nervous system is born in the jungle but individual species" nervous system may experience different jungles.

The common experience of the species can be built by common neural circuit. This is called genetic programs (can detect the wiring of the general circuit) Individual species have to deal with their niche slide 4. First part of the lecture will show the evidence of the function of the visual system depends on the experience of neural activity. The second part is about the mechanism and how the visual experience determines the target selection. Cut the optical nerve of the frog and turned the eye upside down.
