An early stage of conceptual combination: Superimposition of constituent concepts in left anterolateral temporal lobe

Cogn Neurosci. 2010 Mar;1(1):44-51. doi: 10.1080/17588920903548751.

Abstract

Conceptual combination is an essential cognitive process, yet little is known about its neural correlates. In the present study, a categorization task was used to evoke patterns of neural activation for complex concepts (e.g., young man) as well as their constituents (e.g., young, man). A functional region of interest (fROI) within left anterolateral temporal lobe was identified as a possible site of conceptual combination. In this region, the superimposition of activity for constituent concepts reliably predicted the activation pattern for the complex concept built from those constituents.
