The senses from the point of view of an engineer. This course explores the theoretical foundations of the senses from both a systems and a neurophysiological point of view. Emphasis will be placed on understanding the senses holistically rather than individually (i.e. we study the common features that span the various sensory modalities). The course material will involve the application of ideas drawn from information theory, statistical signal detection theory and probability theory. In particular, we cover the following theories: 1) the signal detection approach to sensory analysis (vis-à-vis Donald Laming's theory of differential coupling), the information encoded by sensory neurons, generalized Fechnerian psychophysics (e.g., the entropy theory of Kenneth Norwich), and finally the probabilistic approach to perception. Along the way, concepts crucial to the study of sensory system are also introduced including: the identification and categorization of sensory stimuli, reaction time, decision-making processes, differentiation of stimuli, the limits of perceptibility, and large-scale integration of sensory information. The course will also consider applications of sensory research to pattern recognition, multimedia and biological computers. Course work will involve surveying the existing literature, doing a research project in small groups and a final examination. No biology background is required although some familiarity with the concept of probability is preferred.
