the neurobiology of semantic memory

Article Subject Area(s) Neurobiology Disciplines. 102-115.

This meta-analysis aimed to identify neural activation patterns present during semantic processing in ASD. Table 3: Summary of data showing the role of BDNF in memory and anxiety. (? This chapter reviews evidence that conceptual knowledge about concrete objects is acquired through experience with them, thereby … In contrast, semantic memory is conceptualized as the retrieval of general conceptual knowledge divested of a specific spatiotemporal context.

In essence, our semantic knowledge determines how we understand and interact with the world around us. This study focuses on semantic memory retrieval, which is sensitive to cognitive changes due to aging. Recent neuroimaging studies demonstrate two striking results: the participa Neurobiology of Memory 1. Semantic memory is the component of long-term memory that stores our concepts about the world. Trends in Cognitive Sciences 15 (11):527-536 (2011) Semantic memory includes all acquired knowledge about the world and is the basis for nearly all human activity, yet its neurobiological foundation is only now becoming clear. Human brains acquire and use concepts with such apparent ease that the neurobiology of this complex process seems almost to have been taken for granted. This chapter examines the neural correlates of semantic impairments, leading to an examination of theories of semantic memory motivated by analyses of semantic breakdown in individuals with degenerative and acute neurologic conditions.

The Journal of Neuroscience 16 (1996): 5233-5255. : although authors claimed that anxiety was unaltered in this study, it contradicts the original anxiogenic interpretation of the social defeat model (also see [158]).) Patients with damage to the left prefrontal cortex (LPC) often have difficulty retrieving words in response to specific cues (e.g. Jeffrey R. Binder & Rutvik H. Desai. Each chapter makes the key concepts transparent and accessible to a reader with minimal background in either neurobiology or psychology and is extensively illustrated with full-color photographs and figures depicting important concepts and experimental data. The flexible nature of semantic representations is posited to underlie a host of sophisticated cognitive endeavors, such as This knowledge is essential for recognizing entities and objects, and for making inferences and predictions about the world.

Despite the numerous imaging studies investigating this language domain in ASD, there is a lack of consensus regarding the brain structures showing abnormal pattern of activity. - "Neurobiology of Memory and Anxiety: From Genes to Behavior" This knowledge is essential for recognizing entities and objects, and for making inferences and predictions about the world. The Neurobiology of Semantic Memory. KO: knockout (/), HZ: heterozygous (+/) mice. Memory consolidation and the hippocampus: Further evidence from the study of autobiographical memory in semantic dementia and the frontal variant of frontotemporal dementia. Semantic memory is a form of long-term memory that comprises a person’s knowledge about the world. According to the standard view of semantic memory in cognitive neuroscience, the hippocampus is necessary to first acquire new semantic words beginning with a specific letter, the names of objects belonging to a specific semantic category), even in the absence of a frank aphasia [1]. How is this kind of knowledge acquired or lost? Semantic memory is an individual's store of general conceptual knowledge accumulated and abstracted from previous experiences, without a specific spatial or temporal context. 10.1016/j.tics.2011.1 0.001 The neurobiology of semantic memory.

Brain Regions Related to Semantic Memory . instances of learning – including the context and source of the memory), semantic memory (facts, relations, general knowledge and understanding, not bound to a particular context) and primary or working memory (Tulving, 1995).

Chrysikou 2 , and Sharon L. Thompson-Schill 3 1 Basque Center on Cognition, Brain and Language, San Sebastian, Spain; 2 University of Kansas, Lawrence, KS, USA; Common examples of semantic memory include remembering a friend’s name and identifying famous figures such as presidents. Semantic memory refers to general knowledge about the world, including concepts, facts, and beliefs (e.g., that a lemon is normally yellow and sour or that Paris is in France). Semantic memory includes vocabulary and word meanings, conceptual information, and general facts about the world (Tulving, 1972). The processes and mechanisms implicated in retention and retrieval of memories as they age is an enduring problem in cognitive neuroscience. Second, semantic memory is highly dependent on environmental exposure (e.g., I know that trains in the Netherlands are blue and yellow, but if you haven't been there, you probably don't), and thus creating an appropriate semantic memory task will vary by demographic (much … The neuroscience behind semantic memory has long been a subject of debate.
