Using interoception as a keyword, this manuscript has summarized how changes in the somatic responses, especially internal physical state, are encoded and how the processing of interoceptive information affects the memories of episodes and events. Impact of interoceptive information processing is discussed frequently in the context of affective neuroscience. On the other hand, its influence to episodic memory has not been studied well. Changes in the internal physical state are associated with various memory processing, such as emotional memory and recognition judgement. For understanding the relationship between somatic responses and memory more precisely, we focused on the following issues in this manuscript; i）emotional arousal and bodily responses, ii）effects of bodily responses on memory encoding, iii）judgments related to memories and bodily response and iv）insular cortex and memory consolidation. Through this manuscript, the author presented the possibility that change in the somatic responses itself has a role in latently supporting the encoding and recollection process. By reviewing the newly discovered findings and data accumulated on memories in this light, it can contribute to present the new picture of memory processing.
