This refers to how genes can influence behavior by directing the production of proteins that affect various biological systems, including the nervous system.
Think of your genes as a blueprint (gene expression) for building a robot (you). The way this robot acts (behavior) is based on how it was built according to the blueprint.
Epigenetics: The study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself.
Behavioral Genetics: A field of study that examines the role of genetic and environmental influences on behaviors.
Neurotransmitters: Chemicals in our body responsible for transmitting signals across nerve endings. Their production can be influenced by gene expression.
