PSY210H1 Lecture Notes - Lecture 4: Color Vision, Behavioral Enrichment, Amblyopia
Document Summary
Kitten visual cortex shut one eye other eye takes over because input came from one eye, so a specific part of the brain was only responsive. Part of your brain that computes retinal image will not get enough experience.

There is a sensitive period for visual development. Rat environmental enrichment a cage with bare necessities vs. a very exciting cage increase in the number of dendritic spines for rats in the enriched environment, and they also do better at rat-specific tasks. Fetal frog belly cells place them on mouth region, and the cells which were meant to develop a belly develop into a mouth. You can do this to a salamander too nature/nature interaction. Graph of milestone overlays the average of movements over age.
