Talking Brains Down Under

Greig de Zubicaray's comment on our new survey feature reminded me to highlight the nice body of brain-language fMRI work coming from Down Under. Greig and colleagues at the University of Queensland have been pumping out an impressive number of very cool papers on lexical processing both in perception and production. The work is thoughtful, and psycholinguistically informed. A few sample citations are below. Their work is definitely worth paying attention to.

Thanks very much for the kind words, Greg. Rest assured we spend quite a bit of time discussing your and David's work in the lab and seem to have become addicted to your blog too. I forgot to mention in my last post that we've also investigated whether Iacoboni and colleagues' human mirror neuron system (MNS) for hand/finger movements (Broca's area, IPL, posterior STS) shows preferential activity during perception of hand action words. Results much the same as our somatotopy study. Abstract just submitted to the CNS meeting.
