Describe the physical state of the genome when genes are active and inactive. Often, the physical characteristics of genetically identical twins become increasingly different as they age, even at the molecular level.

Explain why this is so (use the terms “environment” and “epigenome”). Name 3-4 environmental factors that influence the epigenome and describe their effects.

The rat nurturing example shows us how parental behavior can shape the behavior of offspring on a biochemical level. Discuss how this relates to humans and include the personal and social implications.

Explain how the food we eat affects gene expression. Can the diets of parents affect their offspring’s epigenome? Why is converging evidence the best kind of evidence in the study of brain function?

If you were interested in whether a particular brain area was involved in a specific behavior, what neuroscience methods could you use?

If you were interested in the precise time in which a particular brain process occurred, which neuroscience methods could you use
