Left-brain specialization for speech. Ongoing studies are investigating patterns of laterality in normal subjects throughout the life span and in children with learning problems. The Auditory Neuroscience Laboratory is equipped to record and analyze scalp-recorded neurophysiologic responses and to measure behavioral speech perception in humans. The laboratory also includes facilities for direct intracranial recordings in animals. Aging affects hemispheric asymmetry in the neural representation of speech sounds.
Thalamic asymmetry is related to acoustic signal complexity.
