dc.description.abstract
What determines the laterality of activation in motor cortex for words whose
meaning is related to bodily actions? It has been suggested that the neuronal
representation of the meaning of action-words is shaped by individual
experience. However, core language functions are left-lateralized in the
majority of both right- and left-handers. It is still an open question to what
degree connections between left-hemispheric core language areas and right-
hemispheric motor areas can play a role in semantics. We investigated
laterality of brain activation using fMRI in right- and left-handed
participants in response to visually presented hand-related action-words,
namely uni- and bi-manual actions (such as “throw” and “clap”). These stimulus
groups were matched with respect to general (hand-) action-relatedness, but
differed with respect to whether they are usually performed with the dominant
hand or both hands. We may expect generally more left-hemispheric motor cortex
activation for hand-related words in both handedness groups, with possibly
more bilateral activation for left-handers compared to right-handers. In our
study, both participant groups activated motor cortex bilaterally for bi-
manual words. Interestingly, both groups also showed a left-lateralized
activation pattern to uni-manual words. We argue that this reflects the effect
of left-hemispheric language dominance on the formation of semantic brain
circuits on the basis of Hebbian correlation learning.
