Abstract:

The major concern of this years research was modeling the neural systems of the barn owl that determine the elevation of sound sources. Models of the nucleus ventralis lemnisci lateralis pars posterior VLVp and the lateral shell of the central nucleus of the inferior colliculus ICL were developed. Computer simulations demonstrated that these models could account for the most salient experimental phenomena. Future work will test predictions of the models, and hopefully lead to a closed-loop interaction between theory and experiment.
