All Talk and No Action: A Transcranial Magnetic Stimulation Study of Motor Cortex Activation during Action Word Production

@article{Oliveri:2004, abstract = {A number of researchers have proposed that the premotor and motor areas are critical for the representation of words that refer to actions, but not objects.

In the present study, we used single- and paired-pulse transcranial magnetic stimulation to test the hypothesis that left primary motor cortex is activated during the retrieval of words (nouns and verbs) associated with specific actions. We found that activation in the motor cortex increased for action words compared with non-action words, but was not sensitive to the grammatical category of the word being produced. These results complement previous findings and support the notion that producing a word activates some brain regions relevant to the sensorimotor properties associated with that word regardless of its grammatical category.}, address = {Cambridge, MA, USA}, author = {Oliveri, Massimiliano and Finocchiaro, Chiara and Shapiro, Kevin and Gangitano, Massimo and Caramazza, Alfonso and Pascual-Leone, Alvaro }, citeulike-article-id = {1630079}, doi = {http://dx.doi.org/10.1162/089892904322926719}, journal = {Journal of Cognitive Neuroscience}, keywords = {action, language, motor-imagery}, month = {April}, number = {3}, pages = {374--381}, posted-at = {2007-09-07 10:03:19}, priority = {2}, publisher = {MIT Press}, title = {All Talk and No Action: A Transcranial Magnetic Stimulation Study of Motor Cortex Activation during Action Word Production}, url = {http://dx.doi.org/10.1162/089892904322926719}, volume = {16}, year = {2004} }
