Scholarcy highlights

  • We studied the effect of auditory stimulation upon cerebral glucose metabolism in young normals
  • The stimulus consisted of a non-English discourse which was presented monaurally to 10 normal blindfolded subjects; the opposite ear was plugged
  • Significant asymmetries in metabolism were found at the temporoparietal junction, inferior parietal region, insula and corpus collosum
  • The left frontal speech areas remained unaffected. These findings demonstrate that in man the primary auditory pathways retain a contralateral organization
  • Cerebral activation induced by non-meaningful verbal stimulation is widespread within the left temporal and parietal regions but does not impact upon the frontal speech cortices
