Semantic memory

  • Daniel Saumier
  • Howard Chertkow


Our concepts about objects, states, and events are stored in a cognitive structure termed semantic memory. There are several types of neurologic disorders that may cause impairments of semantic memory. Clinical evaluations of these impairments are complex, because semantic memory is linked to other cognitive systems that, when damaged, may produce related syndromes or difficulties. In an attempt to gain further understanding of these breakdown patterns, we review data from both neuropsychologic and brain activity research that have been concerned with how object concepts are represented and localized in the brain. Although these data have spawned varying and controversial views regarding the content and organization of semantic knowledge, converging evidence suggests that semantic memory is mainly localized in the posterior region of the left temporal lobe, and that particular categories of knowledge may be represented in different but overlapping regions within this area.

This functional magnetic resonance imaging study shows that artefacts and abstract nouns recruit similar cortical regions of the brain (left prefrontal and left posterolateral temporal regions). These results are inconsistent with the view that artefacts are represented in terms of sensory-motor properties, presumably because such properties would presumably not be involved in interpreting meanings of abstract nouns. These neural networks would differ from those involving animal concepts, which were found to be preferentially associated with visually based processing regions of the left ventromedical occipital cortex.PubMedCrossRefGoogle Scholar
