It has a close relationship with semantic memory and episodic memory and is also connected with many other psychological cognitive processes, such as the emotional process, self referential process etc. Accordingly, the neural correlates of autobiographical memory consist of many brain areas, including the frontal lobe, temporal lobe, superior parietal lobe and the adjacent occipital area etc. All of the brain areas mentioned above are mainly on the left hemisphere. This article summarizes the previous researches on autobiographical memory and its neural correlates. Given the complexity of autobiographical memory, we divide different cognitive processes of autobiographical memory into 5 operating components from the perspective of memory system. These operating components include semantic component, episodic component, self referential component, emotional component and general cognitive processing component (cognitive process related to general memory retrieval) and each component has its underlying neural correlates. What is more important, these operating components interact with each other coherently within the autobiographical memory system and this article discusses these interactions and connections in depth. These interactions analyzed in this article includes the semantic episodic interaction, the self referential processing general cognitive processing interaction, the emotional episodic interaction, the general cognitive processing episodic interaction and the general cognitive processing emotional interaction. By taking the interactions among the operating components into consideration, different ideas and opinions to integrate the experiment findings are offered, and new ways and solutions to settle some heating debates in the field of autobiographical memory are proposed. Furthermore, this article points out that even though the operating components of autobiographical memory system are closely connected with one another, the previous researches didn't pay enough attention to it. This article analyzes two problems existing in the previous studies. First, most of the previous researches spent much effort in analyzing the different activated brain areas among different experiment tasks, while leaving the common brain activation alone, which might reflect the interaction and connection among the operating components. Second, those studies investigating neural correlates of autobiographical memory using brain imaging techniques tended to overlook the different brain activations at different time points, and these temporal differences may carry important information about the neural mechanism of autobiographical memory. Finally, the article proposes two analytical methods in order to solve the problems mentioned above to some extent. First is using multi voxel analysis instead of the conventional analysis method to reveal the useful information held by the common activated brain areas, second is employing time series analysis to analyze the changes of brain activation pattern in the temporal dimension. In sum, if researchers are going to investigate the neural mechanism of autobiographical memory thoroughly and offered more convincing evidence, they should treat the various cognitive processes of autobiographical memory as a whole, take the interactions among different components into consideration and pay more attention to the neural correlates underlying these interactions.
