The neural basis for simulated drawing and the semantic implications Export

Simulated drawing recruited a large, distributed network of frontal, parietal, and temporal structures.

The activation within the inferior temporal cortex was associated with visual semantic processing and semantic mediated naming. We suggest that the anterior inferior frontal activation is linked to the inferior temporal cortex and is involved in the selection of specific semantic features of the object as well as retrieval of information regarding the perceptual aspects of the object. {\copyright} 2008.}, address = {Department of Physical Medicine and Rehabilitation, University of California at Davis, Sacramento, CA, United States}, author = {Harrington, G.
