Current Research
Dr. Teich's research interests center on information transmission and processing in biological sensory systems. He is studying how acoustical and optical stimuli are encoded into sequences of action potentials at various locations in the auditory and visual systems. He has observed that sensory neural-spike patterns behave as fractal sequences of events, with rates that wax and wane over a broad range of time scales. He is investigating possible synaptic origins of this behavior and developing fractal stochastic point-process models to describe it. He is also studying a new class of neural-based psychophysical models that view the ascending pathways of the auditory and visual systems as amplifying neural networks. These models suggest that detection noise likely originates in the central neural network, rather than at the periphery. He is also interested in how the fractal behavior of the electrocardiogram is modified by heart disease.
