Neuroplasticity is the brain’s ability to heal, grow new connections and reorganize in order to adapt to an environment. In early life, environmental factors are crucial to brain development because the brain is acutely sensitive to the world around it. Rosenzweig’s research supports that the habitat in which a rat lives in affects its neuroplasticity. In Spitz’s research, it is evident that a mother's presence in a child’s life is crucial to brain development. Harlow’s research may suggest that comfort is necessary for development as well. Environmental factors such as habitat, a mother’s presence and contact comfort have proven to be significant in development of the brain. In Rosenzweig's experiment, there were three conditions for
