title: [Role of the thalamus in auditory lateralization: anatomic studies].
abstract: Study of human thalamus cells architecture failed to demonstrate any significant asymmetry between the two thalami in the pulvinar region. In contrast, asymmetry, more pronounced on the left side, exists in the posterior lateral nucleus. Relations linking this nucleus to the inferior parietal region were confirmed by histologic findings in dyslexic patients. On the other hand, the functional asymmetry for specific vocalizations demonstrated in the macaque does not correspond to asymmetry of the cerebral cortex or inferior corpora quadrigemina but to asymmetry of the median geniculate bodies, a finding correlated with auditory functional dominance.
