Computational Models for Central Auditory Neurons
We have explored a number of computational models for neurons in the ascending auditory pathway, from the brainstem through the midbrain. Our current efforts are focused on modeling the responses of neurons in the auditory midbrain. We are developing a comprehensive model that can explain several of the key response properties of these neurons. Our goal is a single model that is able to accurately describe responses to a number of stimulus paradigms. Such a model will be valuable in understanding the role of this brain region in processing of complex sounds.
