Motor cortex and hand motor skills: Structural compliance in the human brain

Katrin Amunts, Gottfried Schlaug, Lutz Jäncke, Helmuth Steinmetz, Axel Schleicher, Andreas Dabringhaus, Karl Zilles
1997 Human Brain Mapping  
Lacking a direct in vivo measurement of the primary motor cortex in humans, we assumed that the ILPG is a measure of the size of the primary motor cortex.  ...  Recent studies in humans and nonhuman primates have shown that the functional organization of the human sensorimotor cortex changes following sensory stimulation or following the acquisition of motor skills  ...  There is also previous evidence that the primary motor cortex might show a structural correlate of handedness.  ...
