Some additional influences shaping the development of behavior

The potent role played by neuroembryological forces in shaping brain development and function is well documented in Nowakowski's article. This discussion outlines several additional mechanisms whereby experience may directly influence brain structure and/or function. One such mechanism is the observation that altered sensory input in older primates may lead to anatomical and functional reorganization of sensory cortex. Another is the experimental evidence indicating that temporary disruption of social attachment bonds in young primates may produce longstanding alterations in behavior, immunological, and possibly other types of physiological functioning. Thus several routes exist whereby postnatal or even adult experiential influences may produce long-term alterations in behavior and physiological functioning, perhaps mediated by both anatomical and functional reorganization within the CNS. It is important to take into account all such potential mechanisms when considering the complex interplay between brain structure and function, experience, and behavior.
