Cerebral hemispheric blood flow velocity differences in left- and right- handers: functional trans-cranial Doppler ultrasonography

It is a well known fact that language functions are primarily related to the left hemisphere in right handed individuals, there is still no agreement about hemispheric language dominance in left handers. The aim of this study is to evaluate the possibility of using functional Transcranial Doppler ultra sonography (TCD), as a non-invasive method for investigation of hemispheric language dominance and also to explore possible gender influence on hemispheric language representation. We performed functional TCD during a word generation task, in 62 healthy volunteers
