I would check these out:

Matthew A. Johnson, Nick Turk-Browne, and Adele E. Goldberg. submitted. Neural systems supporting the learning of novel linguistic constructions.

Kachina Allen, Francisco Pereira, Matthew Botvinick, and Adele E. Goldberg. 2012. Distinguishing Grammatical Constructions with fMRI Pattern Analysis. Brain and Language 123: 174-182.

Actually the first paper is not available yet (I had seen this work at a conference last year). But for this kind of issues, Adele Goldberg at Princeton would in general be a good person to follow.

Victor, Thank you a lot.

You are welcome!
