Identity is the essence of performance and performance is the essence of identity. Without identity our performance does not assume any cultural significance. Our relative identity allows our performance to be located in the socio-cultural space. Our identity forms the foundation for the discursive significance of our performance. However, our identity is not unique, it is established by performing a pre-existing script. The biological basis of identity can be understood by applying learning theories and by analyzing how these leant behavior is embedded in our neuronal network in the brain and how these behavior patterns are controlled by psychological factors to result in the identity we observe. Recent developments in the fields of neuroscience and functional neuro imaging have enabled us to study objectively the process of neural mechanisms and map areas of brain that are involved in learning various behavior patterns. These neuronal networks and the neuro transmitters play a key role in memory and behavior of animals. Aby studying the particular pattern of behavior and the brain area that mediates that behavior it will be possible to determine neuronal networks that control core identity characteristics and that control other less important characteristics. With the emergence of studies in neuroplasticity the possibility of relearning behaviors through new neuronal pathways may open new avenues to treat conditions that affect identity. Understanding the biological basis of identity will lead to widening of research area and better understanding of the concept.
