Auditory communication often involves sounds that have                          complex frequencies, or spectra, and complex timing relations, or               temporal pattern.  Some analysis of the spectral and temporal                   components is known to occur low in the brainstem, which contains               groups of nerve cells called the auditory nuclei.  These neurons                send projections to higher centers in the brain for further                     analysis.  Frogs have provided particuluarly useful models for                  study, since they are well-studied, their mating calls are                      relatively simple and stereotyped, and the brainstem has somewhat               simpler structure than in mammals.                                                                                                                              This project will use the frog model to examine how                             behaviorally meaningful features of complex sounds are processed                in the brain.  Two particular nuclei in the brain stem will be                  studied by electrophysiological recording of single cell                        responses to a wide range of artificial and natural acoustic                    signals.  Building on past work on recognition in the frequency                 domain, this project will aim primarily to determine the                        selective importance of certain features of amplitude modulation                and temporal pattern, and the neural codes of response patterns                 that may be used to discriminate among different signals.                       Results will be relevant to studies of communication behavior, of               complex sound analysis, and important to the general sensory                    problem of signal processing.
