ELEN E6906: Information Representation in Sensory Systems
In the last 20 years, patch-clamp recording and gene cloning techniques have made it possible to uncover how sensory stimuli are detected. Detailed studies have been made about the electrical responses of the key sensory receptor cells of the vertebrate body and from many cells of invertebrates. A large number of important molecules from sensory receptors have now been identified, cloned, and sequenced, making possible a detailed understanding of even complex signaling cascades of vision and olfaction.
This interdisciplinary course focuses on the cellular mechanism of sensory transduction. Whenever possible, the course will introduce computational models of sensory subsystems. Topics covered include: Introduction to Sensory Systems, Mechanisms of Sensation, Channels and Transduction, Modeling and Analysis of Stochastic Channels, Chemoreception and the Olfactory System, Information Representation in the Olfactory System, Mechanoreceptors and Touch, Detection of Movement and Sound, Photoreception and Vision, Time Encoding and Machine Learning.
