New evidence regarding the hub-and-spoke semantic memory network theory

Takeaway

  • The authors identified the left fusiform gyrus as the hub of the semantic memory network, functioning with nine separate regions for semantic processing and the left calcarine for color modality-specific semantic processing.

Why this matters

    This article provides robust evidence supporting the hub-and-spoke semantic representation theory of memory. Increasing our understanding of the neuroanatomical network of semantic processing will provide researchers with the necessary tools required to eventually develop effective treatments for people suffering from semantic dementia.
