Human behavior
Culture and environment

Human brains, as with those of all mammals, are neuroplastic. This means that the structure of the brain changes over time as neural pathways are altered in response to the environment. Many behaviors are learned through interaction with others during early development of the brain. Human behavior is distinct from the behavior of other animals in that it is heavily influenced by culture and language. Social learning allows humans to develop new behaviors by following the example of others. Culture is also the guiding influence that defines social norms.
