Brain Regions Related to Semantic Memory . The neuroscience behind semantic memory has long been a subject of debate. The disruption of semantic memory as a result of brain damage may have profound negative consequences on an individual's ability to name objects and process concepts. Since Tulving proposed a distinction in memory between semantic and episodic memory, considerable effort has been directed towards understanding their similar and unique features. Though studied for decades, much about it is still unknown, such as the specific brain parts used in its processing. Semantic memory is likely the most important type of memory that facilitates verbal and nonverbal communication and allows humans to share their unique experiences. In essence, our semantic knowledge determines how we understand and interact with the world around us. Semantic memory is a form of long-term memory that comprises a person’s knowledge about the world. 10.1016/j.tics.2011.1 0.001 Title: The neurobiology of semantic memory Author: Jeffrey R.
