Give me a brief synopsis of Rosenweig's Study (More Experience = Bigger Brain)
What is What is 12 sets of three male rats from same litter were assigned to different living conditions at weaning
Remained in these environments for 4-10 weeks
1) Standard condition (SC)
-3 animals per cage, food and water
2) Impoverished condition (IC)
- 1 animal per cage, food and water
3) Enriched condition (EC)
-10-12 rats in large cage with lots of toys changed daily, food and water
Cerebral cortex in EC much heavier and thicker
