Hemispheric Asymmetries and Right Hemisphere Activations
|
generic
|
In both tasks, the activations engage large neural networks throughout the left hemisphere but also homologous regions in the right hemisphere. This seems to be less true for the sentence judgment task, in which a clear preference for the left language dominant hemisphere can be observed, whereas the sequence judgment task seems to engage regions in both hemispheres almost equally. This could be related of course to the existence of a functional specialization in the left hemisphere for the processing of meaningful linguistic stimuli, as revealed by the network activated specifically for the judgment of sentences alone as.
