Regional cerebral blood flow (rCBF) was studied by single photon emission computerized tomography (SPECT) of inhaled xenon-133 in six normal volunteers during various language, articulatory, and control conditions. Language production increased rCBF in predominantly left-sided cortical and subcortical areas. The involved regions were anatomically related to a left frontal area (Broca's), to both caudate nuclei, to a left thalamic/pallidal area, and bilaterally in retrorolandic areas. The failure to demonstrate lateralized retrorolandic activity is thought to reflect the complexity of the tasks.
