    Jon Kaas

    Distinguished Centennial Professor of Psychology
    Associate Professor of Cell and Developmental Biology
    Professor of Radiology and Radiological Sciences

    Kaas's major research interests are in the evolution and functional organization of sensory-perceptual, cognitive, and motor systems, especially in primates, in the development of these systems, and in how these systems are plastic in response to injury and use in developing and adult brains. Special research emphasis is placed on studying visual, auditory and somatosensory systems, but current studies are also concerned with multimodal and sensorimotor integration in parietal and frontal cortex. Research questions are addressed with a range of electrophysiological, neuroanatomical, biochemical, and behavioral techniques. Teaching interests are in neuroscience, biological psychology, and animal behavior.

    Current Research

    • Single and multielectrode recordings of neurons in primary somatosensory cortex of monkeys.
    • Optical imaging of functional subdivisions of visual cortex in monkeys.
    • Studies of anatomical connections of neural networks in brain systems devoted to somatosensory, visual, auditory, motor, and gustatory functions in monkeys.
    • Studies of brain architecture.
