Acoustic Properties of Central Auditory Pathway Neurons during Phonation in the Squirrel Monkey

  • P. Müller-Preuss


The present work is based on the assumption that the complex nature of acoustic communication within certain vertebrates, such as primates, requires control circuits between structures involved in phonation and audition. This means that interactions between those structures exist, and that acoustic communication is not only carried out through genetically preprogrammed processes. Control of an individual s own vocal output can take place via the ear (auditory feedback), via somatosensory structures for example in the larynx (proprioceptive or tactile feedback), or via neuronal circuits in the brain itself (central control). An example for the importance of auditory feedback is the dramatic consequence of deafness in humans when learning to speak (Seeman, 1969). As far as central control circuits are concerned, several studies have shown that vocal activity can influence peripheral structures of the auditory pathway, such as the middle ear (Suga and Jen, 1975) , and also central stations, such as the lateral lemniscus (Suga and Shimozawa, 1974) and the inferior colliculus (Schuller, 1979).
